Description

Thread-reinforced tubular or tubular materials and processes and device for their manufacture. Summary A device for manufacture of thread-reinforced tubular or tubular products in a continuous manner.

This device comprises a series of thread spools. The thread material The coils are passed through a resin container and a fixed mandrel to form the longitudinal strands of the hose or pipe. The thorn points ir. essentially the same inside size and shape of the hose guide to be produced Pipe material. The mandrel extends through a plurality of spirals winding thread winding devices with such training to opposite spirally wound Strands of thread attached to the in between Apply layers of the longitudinal strands. The mandrel also extends through a Pair of circumferential thread winding devices for laying circumferential strands on the on the first surface in opposite directions to each other and in superposition on the spiral-shaped, immediately continuing E: ndstrnge.

The multiple layers of such strands resting on the solid mandrel are wrapped in the R.F. hardening zone (radiofrequency heating zone) on the mandrel, which also extends into the hardening zone. After the resin matrix or resin compound has been hardened, what is ultimately formed and hardened tubular or tubular material is pulled from the mandrel by a pulling unit.

A number of embodiments for direct manufacture of wound tubular or tubular materials is described. At a Another embodiment is the device on a moving support, for example a boat, attached, with the continuous hose or tubing of is laid down on the moving carrier. In another embodiment. According to the invention, a rectangular mandrel is used for winding hose or pipe sections with an approximately rectangular cross-section used for the construction of Ladder rails and similar components are used can.

Description The invention relates to certain new and useful ones Improvements in an apparatus and method for making a filament reinforced Hose or pipe rate as and particularly to an improved device and an improved process for the formation of thread-reinforced pipe or hose materials in a continuous manner, this hose or pipe material as pipelines can be used for fluid media with high performance properties.

This hose or pipe material is also very useful and Useful when creating building elements or when using them on any one place where tubular members are normally used.

The application, the acceptability and reliability or operational safety of hose or pipe products formed from materials other than metal are are increasing rapidly. Injection molded thermoplastic pipes or conduits are largely used for service water systems, sprinkling or spray systems or the like. used. If that used in the manufacture of these non-metallic pipes thermoplastic resin has the appropriate properties, can moreover the pipes are used to transport chemical and waste liquids, metals being subjected to severe chemical attack and severe corrosion sin. However, extruded or injection molded thermoplastic pipes are regarding limited their pressure holding capacity. Pipelines for long distances (long-run pipe lines) have to work at a relatively high pressure. In a similar way Way also need utility pipelines for household purposes, those for supply from locations on hills and mountains are required to work at high pressure. In the chemical industry in particular flowable media in pipes at increased Pushing transported.

Until recently, only metal pipes or pipes could handle the fluid working pressure above about 7> 05 kg / cm2 (10Q psi) at / a pipe diameter of about 2.54 withstand cm (1 inch).

Normally tap water is of the kind given to criminals compared to metal pipes depending on the chemical components of the water corrosive. In addition, most chemicals attack metal pipes> and sometimes these reactions can be very strong and destructive. To avoid this corrosion problem were pipes of a diameter that were used to conduct flowable media at proportionately low pressure were used, made of copper. Larger diameter pipes were made of steel and stainless steel, but of all types required regular renewal. Also, many of the steel pipes were using protective inner linings made of ceramic materials and thermoplastic materials Materialvien, rubber or the like. Equipped.

However, the pipe joints were vulnerable to the pipe lining only the inner round wall of the pipe from corrosion and not the connecting one Joint protected. The measures to bridge these joints or joints are generally expensive and often dangerous.

The advent of glass fiber reinforced pipes was a major one Progress in solving the problem related to recording and maintaining corrosive media at elevated pressures. The glass threads were in the cylindrical wall of the tube inlaid in a way to withstand tension as well as withstanding the normal stresses and strains of a pressurized cylinder. In addition, the thermosetting resin binder materials are capable of being corrosive to withstand a wide variety of chemicals. Also owns the Glass reinforced resin bonded pipe has an additional advantage over a Metail pipe by having a higher specific strength, much higher corrosion resistance and has a lower relative cost. It also has a higher degree of Reliability and operational safety not only in the high itself, but also in the same way in the connection points.

There are a number of technically available manufacturing approaches of filament-wound tubing, however, any of the methods currently available are and each of the available apparatuses is only capable of being relatively separate to form short sections of pipe. These modes of operation are necessarily costly and include a large proportion of laboratory costs as well as a considerable amount Production time for the manufacture of pipe sections of fixed length. There is a few currently available devices and procedures for making continuous lines, but all of these working methods under very suffer serious disadvantages. In one of these ways of working, one becomes continuous moving mandrel is used, successive mandrel sections so attached are that end to end, and continuously fed through a machine in which a thread is wound over it. However, the different Mandrel sections are separated so that the cured laminate into individual sections can be slid and removed from the mandrel sections. With another Working method for the production of continuous tubes forms an endless metal belt a mandrel by rotating it in a spiral configuration so that it resembles the shape of a hardened pipe. Then the thread is on wound this makeshift spiral mandrel. However, this device proved itself not particularly successful. moreover, she is very good at work expensive and quite ineffective.

A widespread inclusion of tubular members made from Reinforced plastics are manufactured, also entered other branches of industry on. It had recently been found to be # fiber reinforced compositions or masses also effective in the manufacture of structural elements or Components, such as ladder rails or the like. be used can, however, have structural elements or components in contrast to gaseous ones or pipes carrying or conducting liquid media are not necessarily symmetrical Cross-sections. This applies in particular to conductor rails or the like. to. In the preparation of of ladder rails, it is necessary to have two relatively thick opposite end walls connected by two relatively thin side walls are. Other structural elements or components such as T @ ag or support posts that consist of Reinforced compositions can be formed are in their cross-sections also variable. However, there is no effective technically available device or mode of operation for the formation of rchrode tubular structural elements or Parts made from thread-reinforced compositions.

It is therefore a main object of the invention s an apparatus and a process for the continuous production of shaped or thread-reinforced hose To create pipe materials. Another object of the invention is to provide a method and a device of the specified type, wherein a permanently attached metal mandrel is used for taking up twisted strands of thread and this is really good hardened and removed from the mandrel in a continuous process. Farther The invention aims to provide an apparatus and a method of specified type, each effortlessly and conveniently for the production of pipes or Hoses with a great variety of sizes and shapes can be. Another specific purpose of the invention is to provide a Apparatus and a method of the specified type, wherein the costly need for a large stock of thorns is avoided. The invention also aims that Manufacture of thread-reinforced pipes or hoses of high performance, ' those for guiding corrosive liquids at high flow rates are able to withstand the high internal pressures. Another purpose of the Invention is to provide an apparatus and a method of the aforesaid Kind, being the Device on a moving support for the continuous deposition of pipelines from the carrier as it moves is appropriate. Yet another purpose of the invention is to provide a method and a preparation of the kind specified, necessary for the manufacture of reinforced articles with non-uniform cross-sectional shapes, these items at the manufacture of structural elements or components can be used.

Many of the terms used in the thread winding technique, such as e.g., spiral "and" helical "have become used to describe a manifold used by locations or states and therefore have no specific or certain meaning as such. Therefore, the following definitions are made below given to these expressions for the purposes according to the invention a certain Ascribing importance.

Lengthways: A layer of one or more strands that are essentially axially with a mandrel and generally parallel to the center axis of the mandrel are. A lengthwise layer should not be more than one Angle of loO deviate from the axiiilan center line of the spine. The main criterion is that this strand meets the requirement of axial tension or expansion.

Helical or helical: a layer of one or more Strands wrapped around a mandrel so that they are the axial center line of the Surrounds the mandrel, the angle of the screw line formed by the strand (helix angle) with respect to the axial M + ttelline of the mandrel is in the range of about 10 ° to 850.

Perimeter: A layer of one or more strands running around the perimeter of the mandrel and with respect to the axial centerline of the mandrel has an angle of about 850 to 950; the main criterion is that this Strands. meet some type of burst load requirement.

Spiral: A layer of one or more helicals Strands that are applied in a form in which the bandwidth is a fixed Relationship to the screw angle and the mandrel diameter in such a way that a continuous solid pattern is obtained, each of the strands in one adjacent relationship are arranged side by side (Most of the helical or helical turns or windings according to the invention are in the form of spiral turns; however, the term 11screw as used here includes or helical "also" spiral) The angles for the above four types of wraps are not necessarily critical as such and are merely listed to define the type of winding that will be applied. If the Winding or the layer is designed in such a way as to provide a high burst strength, however, the winding is generally a circumferential winding. If the winding or Location for creating component forces for high axial and tensile or elongation loads is formed, the winding or layer is generally helical or helical Winding. When the winding or layer is used to create high axial loads is formed, the winding is generally a longitudinal winding.

The expressions below have also been somewhat inaccurate Meanings are used and therefore the following definitions are given below: Thread: A single thread generally used for reinforcement purposes, for example made of glass, boron or graphite or the like.

Plied threads or ends: A group of threads that are in the shape of a Strand are collected, with each of the threads essentially in a parallel arrangement is present and forms a substantially flat band, the number of threads depends on the material used (in a normal Easer glass, in a End or plied maggot material 204 threads used).

Vorarn (roving): One or more thread ends or plied threads strands are usually arranged in a relatively thin, flat band normal E-glass fiber material, the roving has oo den or strands of thread, e.g. a 60-end roving.

After that, a plurality of worm or helical rigidity in reverse spiral to that of the first Winding point around the hose that at the second winding point is formed, wrapped.

This trinity of longitudinal strand feeders and the helical ones Windings result in spots that can be repeated around a hose with a to form the desired wall thickness.

Reversely attached circumferential cords can be applied to the formed tube to be wound at the last two winding points. Any desired Provide number of winding points and the desired type of windings for each Apply these winding points. You can also use longitudinal strands in places apply that lie between one or more of these winding points.

The hose or tube formed on the fixed mandrel, extends into an R-F curing unit in which the matrix is cured. The tube then extends out of and into the curing unit a pulling unit in. The pulling unit is provided to pull the hose from the continuous pulling off the solid mandrel as it is formed. In some areas of application for the hose or pipe material, with the hose or pipe material at is carried out at a regulated rate (paid out), it may be desired be to use a braking unit that regulates the speed of the dispensing of the continuously formed hose is provided. This hose or raw material, which can be manufactured with a desired wall thickness, is generally for use as conduits for transporting liquids or gaseous media. By adjusting the position and type of winding points, which are used in the device according to the invention, it is possible to use high pressure lines or low pressure lines or, in particular, lines with desired performance properties highlight.

According to the invention there is also provided some type of hose or pipe winding device created in which a force working impregnation unit in contrast is used to a resin container. For the resin impregnation unit that works with force the hose formed is passed through a sleeve or sleeve (Laufbuchse0, the contains a number of sound drivers. The resin gets into the inside of the liner introduced and into the windings forming the hose by means of the sound driver pressed; in another embodiment according to the invention a hard contact impregnation unit is used used.

In this case the resin is only applied to the surface of the windings guided on the hose wall and into the windings let soak in. Inflatable air seals can be used qn the ends of each of the liners will.

According to the invention there is provided an apparatus in which one of these impregnation units is used in place of the resin container. These impregnation units can be made according to any of the winding locations or selectively be arranged in a desired manner after a number of parking spots.

According to the invention, a continuous hose - or Rohrmaterilaien forming machine created which an extrusion press or injection molding machine including. The extruder is designed to produce hose or pipe materials to squeeze out, which serve as house clothing, around which thread-reinforced strands are wound can be. moreover, there is no need for this type of device for a solid mandrel, since the extruder is a fairly stiff or rigid tube which essentially serves as an in situ mandrel.

Another embodiment of the invention comprises an apparatus which has a liner made of a synthetic resinous material and a fetus Thorn forms. Then the desired number of winding points can be used, around the strands of thread-reinforced material around the lining to wrap. In another embodiment, the lining can be impregnated with resin and hardened to serve essentially as an in situ mandrel.

According to a further modification, the liner need not necessarily be hardened, but can be sealed or sealed along their tngsr) inder will. If the liner is not sealed or welded and hardened, it is necessary to use a solid mandrel that extends at least into the hardening unit extends.

The invention also provides an embodiment in which any of the hose or pipe production devices described above on one moving carrier, for example a ship can be attached.

Since the hose or pipe is formed on the ship, that can formed material are laid out continuously while the ship is moving. In the case of a land vehicle, the vehicle can be moved at the speed which corresponds to the extent of froduction of the pipe, so that the pipe or hose which can serve as a tube, can be carried out continuously. With a ship or boat is the hose or pipe material continuously and underwater during of movement: given up by the ship.

In a further preferred embodiment of the invention will a solid mandrel is used, the cross-section of which is rectangular. With this kind of Mandrel it is necessary to form ladders rails that are used in the construction of ladders be used. When manufacturing rectangular conductor rails, it is desirable to relatively thick opposite end or end walls, which by relatively thinner side walls are connected to form. The device according to the invention is readily suitable for the production of other structural members or components.

Apparatus for making reinforced pipelines The invention is explained in more detail below with reference to the drawing, in which practical embodiments to be shown. A1 denotes an apparatus for producing continuously wound filament-reinforced high-performance pipelines, the device A1 can be erected on a vehicle so that it is substantially movable and can be used to operate from the wheeled vehicle chassis to a floating one Ship, sled or other movable vehicle. In addition, the device A1 can be erected in a fixed position or in a fixed place and moreover in a vertical or horizontal arrangement or in any Position are operated.

The device A1 generally comprises a base plate 1 one end of which is a spool holder or frame 2 with a series of transversely extending Spindles 3 4 for the reception of the usual bobbins of thread materials or the like "Roving" is appropriate. Each of the coils 4 has its own @se 5 provided and the strands of thread 9 from each of the bobbins 4 are through the with each single coil connected @se 5 out.

Any endless thread material that can be bent to fit the to match the cylindrical surface of a geometrically cylindrical rotating body, can be used in the procedure according to the Fund. According to the invention The most popular thread materials are those made of glass. It should be noted, however, that threads made of carbon, quartz, graphite, asbestos Aluminum or the like can be effectively used. Threads formed from lithium and other hair-like crystals, can also be used. A metal wire can also be used with the glass threads in the event that it is desired to mix the fiberglass-reinforced tubing a certain type of Netallkö @ per admit, the pipe material, for example is produced with an electrical conductivity.

The various strands 6 of each of the thread bobbins 4 are over passed a roller 7 attached to a resin container 8, the latter on the base or bottom plate 1 in the manner as shown in FIG. The various strand 6 are spaced apart in the transverse direction from one another the roll 7 passed into a trough 9 forming part of the Bhäiters 8, which is a liquid Contains resin. In addition, the ends are in the liquid resin bath with the help of a niedenbalter @@@@ 10 withheld. Be at the opposite end of the @ Elderly the strands are held in the fluid resin bath by means of a hold-down roller 11. Then the strands are moved upwards from the liquid resin bath and over one another transversely extending roller 12, which is similar to the roller 7, guided.

A pair of squeegee rollers can be used if desired. The resin container 8 has a conventional structure, and therefore more details will be given covered structure of this container not explained in detail.

Any material that is at a certain stage in the process Can be liquefied and softened for a period of time, can be used as a resin binder or so-called "matrix" can be used. The matrix should be sufficient to enter the Feddnmaterial to flow and the spaces between adjacent threads and their Layers before obtaining one rigid state by cooling or completion of the polymerization to form a rigid solid to fill. In addition, the matrix should have the ability to adhere to the stiffener or have reinforcement. Some examples of suitable binders or matrix materials, which can be used in accordance with the invention are various thermoplastic Resins} such as polyamide, polyethylene, folypropylene, numerous folycarbenates, polyester or similar. In addition, thermosetting resins such as polyester can be various Resins of the ihenol and bpoxy type or the like can be used. In general should the thermosetting resins melt to an insoluble, not hot (non heat), softening cup when using heat or a similar working method a mode of operation that triggers the catalytic system (by means of a signal).

Other binders or matrix materials are hard waxes, eutectic ceramic mixtures, eutectic metals, synthetic rubber materials or like that.

On the base plate 1 is an upright stand 13 at a longitudinal distance fixedly attached to the resin container 8, which has a bearing 13 'for carrying one itself has vorwirts extending Donns 14 in a boom position, as shown in Fig. 1 is shown. On the base plate 1 there are also four reversed U-shaped adentraxing brackets or supports 15 for supporting the longitudinal strands of the thread material after leaving the resin container 8 arranged at a longitudinal distance from one another. the U-shaped supports or brackets 15 are with four in substantially on the circumference Spaced eyelets 16 provided, of which the longitudinal strands of the roving for a purpose which will be explained in more detail below.

In addition, four coil carrier frames 17, 18, 19 and 20 Mounted at a distance from each other in the longitudinal direction. Each of the bobbins. en 17-20 comprises a round bobbin support plate 21, which by means of a conventional Electron motor 21 'can be rotated by a Zah @@ adantriebssystems (not shown) can. Essentially, the spool carrying wheels can be equipped with a peripheral drive wheel (pinion gear), which is usually provided with a on the drive shaft of the motor 21 'attached track or spur gear works together.

It can also be a sprocket and chain type drive mechanism come into use. As this type of drive mechanism is in use, which is not explained in detail here.

On each of the bobbin support plates 21 are spindles 22 for support of conventional roving bobbins 22 'rotatably arranged, which are planar from both Surfaces outward extend. The roving bobbins 22 'are in essentially identical to the roving bobbins 4. In addition, each of the plates 21 is designed to have 4 to 10 coils spaced from one another on the circumference on each of the flat surfaces or a total of 8 to 20 coils on each ratte to wear. The terminal ends of the Vorrarns are through eyelets or so-called "redirects" led to a binding adjustment eye (not shown), which can be supported by any conventional structure.

It should be noted that # it is not necessary to use the mandrel 14 with any Equip coating. According to the invention it was found that a mandrel with a Bolted chrome finish is also very effective. It is fiberhaunted with many speeds not necessary to roll the mandrel smooth. In addition to that, it is desirable and expedient the thorn with a. to form a very weak cone or with a weak taper, so that # the free end of the mandrel is slightly diametrically smaller than its undercut Find is. The cone or the taper should be at the point where the mandrel enters the hardening zone described below. This rejuvenation at the. The aim of the mandrel is to alleviate or induce any shrinkage of the Strands wound on it.

From Fig. 1 it can be seen that the upstanding frames 17 and 18 a first right-hand or left-hand, helically or helically winding one Represent winding point W1 or W2. The support frames 19 and 20 represent with the Winding coils each represent circumferential winding points W3 and W4.

The mandrel 14 delimits the inner surface and constitutes the main support element for the production of the endless hose or pipe material according to the invention It may be formed of any suitable material that is opposite to a axial tension that occurs during operation, and against friction that as a result of the abrasion, the uncoated glass fiber reinforcement elements, that move along the length of the spine, occurs, is resistant. Of the The mandrel or a special section of the same must also be used with the hardening media will be discussed below, as well as the mode of curing that may be used for any particular product is used. In addition, the mandrel can with a covering of a suitable outer lining with a smooth surface, for example T @@ rafluoroethylene polymer sold under the trade name "Teflon" is available, or so-called "Cerman" (Cermets) ceramic KetallenX such as high aluminum oxide / silicon dioxide forfeit It should be noted that #, although the mandrel 14 is perpendicular to a circular @ Has cross-section, it is also made with any desired cross-section can be used to produce pipelines with a special cross-sectional shape.

The pipes created according to the invention are produced by that a number of longitudinal strands on the mandrel 14 directly from the roll 11 brings up.

These strands can have an upright guide 23 attached to the support 13? in the in'ig. 1 attached iFt. moreover be the strands through a filing plate or a so-called "carding plate" 23 'a suitable Arrangement and orientation drawn on the mandrel 14. The carding plate 23 'has preferably the shape of one arranged around the mandrel 14 in its circumferential direction Ring and has an opening for each longitudinal strand applied to the mandrel. The plate 23 'can be supported by any conventional support structure (not shown will. The very purpose of these first longitudinal strands is to pull them together and binding or adhering to the mandrel of any spiral or circumferential strands, which are then applied to prevent.

In addition, the longitudinal cords serve as tension elements that lead to recording of the axial band as the tubular member being formed is pulled along the Dorns are capable of. These initial longitudinal strands can be applied in such a way that the later or latter windings are of the circumferential type or helical or spiniform Kind of the outer surface of the mandrel 14 is not based. Similarly, you can Longitudinal strands are so arranged to extend circumferentially around the mandrel 14 to a sufficient extent become so that they essentially envelop the latter.

Then a number of spiral-shaped Windings wound on the outer surface of the first longitudinal strands. It can be seen that the thread material from each of the bobbins through suitable eyelets or so-called. Returns or redirects can be drawn. There is a special eyelet for each spool provided by roving. At the second winding point W one is opposite Coiled snail-2-shaped wrapping or shell on the outer surface of the first helical winding applied. At the third winding point W3 becomes a first circumferential wrap or shell around the outer surface of the helical Winding sinuous. After that, another layer of circumferential strands is applied to the hose formed in this way is applied to the last winding point W4. This last one Layer of Strands will be in the opposite direction to that of the Direction of application of the circumferential strands applied at point W3. on the other hand can add another layer of longitudinal strands to the surface of the first helical Winding before the second helical winding is applied to the winding point T2 can be applied.

It should be noted that each of the strands from the spools 22 'on each Side of the plate 21 is applied to the mandrel 14 at the same point.

Although the device A1 described with four winding points W1 to @r it can be seen that # any desired number of winding positions can be used can get. For example, in the case where the production of High pressure lines are desirable, expedient, G to 8 or more winding positions apply.

It can also be seen that although the winding locations W1 and W2 described as helical or helical winding points surder, and the winding points W3 and W4 were explained as peripheral winding points, too other types of windings can be obtained at these points. For example it may be desirable, one place with a receiving winding, another place with a helical winding and a third place with a circumferential winding or any combination of these 3 in different forms to use. Accordingly, the invention is not to any specific number from winding points and not to any required form of windings limited. In addition, it should be noted that longitudinal strands in the formed pipe material can be inserted between any one or more of the winding locations. For purposes of illustration, according to the invention, as can be seen, longitudinal strands before the first wrap; location and also at each of the subsequent winding locations, namely the points W2 to W4 introduced. In the particularly preferred embodiment when winding, it is desirable to first apply a series of longitudinal strands, which essentially envelop the mandrel at the periphery. After that, the first becomes helical Winding in one direction at a first winding point and a second Helical winding in the opposite direction at a second winding point upset. This three-way combination of longitudinal strands, first and second helical Strands can be repeated in any number of repeats desired obtain the wall thickness of the pipe to be formed. The circumferential development centers will be generally applied fairly at the end of the device. However, it may be desirable be more circumferential wraps at any stage during the Apply the winding process to give the pipe wall a bursting strength.

In the manufacture of thread-reinforced high-performance pipelines it is sometimes only necessary to have two winding points in addition to the cover to use from tgsstrangen. In the case of high-performance pipes, the inner layer must consist of longitudinal strands which essentially envelop the circular mandrel. In general, the longitudinal strands lie directly on the mandrel surface first building layer. The first longitudinal layer of strands must be parallel to the axis of the And must be evenly distributed around the circumference of the mandrel. These strands serve as tension elements in operation (in-process tension elements) in order to produce the To pull pipe wall structure along the dome. They remain in the structure, around theirs proportional share to the necessary component of longitudinal strength that is necessary for the pressure absorption in a cylinder is necessary to contribute. At the first winding point a first helical coil is used with strands around the mandrel underneath at an angle of about 45 °. At the second turning point, a second helical winding is applied to the surface of the first winding and this winding becomes at an angle of 450 but in the opposite direction Direction applied to the first helical winding. Besides, it is sometimes in the case of hanging tubes, a further lengthwise winding at a point between use each of the two helical winding points. The one after this The type of pipe produced by winding patterns was found to be suitable for use in high pressure operations as particularly suitable. In the case of high pressure pipes, additional layers of circumferential strands can be used may be added to meet the requirement for additional burst strength.

With reference to Figures 1 and 3 it can be seen that the mandrel 14 extends into a suitable curing device 24 which is operable on a Stand 25 is attached, the latter being rigidly attached to the upper surface of the base plate 1 is attached. It is possible to use a radio frequency hardening or sonic hardening for to apply the purposes according to the invention. A special radio frequency unit or so-called "R-F" heating unit which can be used according to the invention explained in more detail in FIG. 3.

It can be seen that the mandrel extends into this heating unit the total effective amount thereof. A short section of an aluminum pipe 26 is around the circumference of the mandrel 14 in the manner shown in FIG arranged and creates an annular space 27 between them. In practice, the metallic one is used The mandrel as one electrode and the aluminum tube as the other electrode. By Using a suitable R-F generator (not shown) it is possible to generate the desired radio frequency to obtain in the annular space 27, and thereby the applied to the mandrel 24 winding or to harden the sheath of strands of thread. The outer surface of the mandrel 14 and the Inner surface of the aluminum tube 26 can each with Teflon layers 28 and 29 may be provided, as shown in FIG. 3. The invention is not based on that here described special R-F hardener limited, rather can according to the invention any of the -F or sonic curing units can be used.

The hardening unit 24 is provided for softening or melting and to activate the catalysis system in the thermosetting resin. in the In general, the heating method is chosen to get the right energy Heating a special material to give. You can also use heating Use infrared or heated air or heated gas in some systems. bs however, it has been found that radiofrequency heating is suitable for the purposes of of the invention is much more advantageous, since these units form the resin in the tubular Can harden limb in a very short period of time. Hence the problem is demeanor of the tube has been substantially eliminated from the mandrel. Although it is possible is heated air or gas or infrared heating for some compositions many of the compositions are essentially heat insulating and cure only effectively using R-F or sonic curing procedures. The radio frequency generator usually works in the VHR or UHF range. This latter Dielectric heating method is similar to that in U.S. Patent 2871911 described, method, whereby frequencies such as 1 g megahertz, 27.1 megahertz and 40.6 megahertz can be used. However, 74 and loo megahertz or 194o and 2450 megahertz can be used.

There can also be an alternative type of radiofrequency hardening (not shown, for example, such a type in which a series of electrically charged bars or rods with alternating earth potentials and positive ones Potential is present. In addition, a sound hardening system (not shown) be applied.

In this case, a license maker is used to provide a reasonable Generate amount of energy necessary to harden the resin matrix necessary is. This latter type of system is common in its construction and therefore will not explained here. The term "sound" used here is not based on the energy source is limited, which is within the normal listening range namely approximately 16 cycles to 16 kilocycles per second. The term "sound" also includes the subsonic speed range with about o to IG cycles per second, the Ultrasonic range with around 17 kilocycles per second to 780 kilocycles per second and the supersonic speed range with about 1 to 15 megacycles per second as well as the sound range.

The hardened tube is continuously from the mandrel 14 through a Pulling unit 31, which in iig. 1 is shown schematically, deducted. The pulling unit S1 is in the usual way on a stand 32, which is on the 1 base plate (one) is attached, attached. The pulling unit 31 comprises a pair of endless belts 32 ', which are applied to drive rollers 33 during operation and to the opposite ones Sides of the tube formed in this way are arranged. The pulling unit 31 must necessarily have sufficient tensile force to prevent the friction of the pipe on the mandrel 14 to overcome. However, since the amount of space that is due to the uniqueness of heating and that obtained at the various winding points Unity or crowding comparatively small, eats, the length of the thorn is not excessive great. In addition, the resin itself provides a kind of lubricating activity so that the Tube formed in this way on the mandrel 14 and in the hardening unit 24 is cured can be easily removed from the mandrel 14 by means of the pulling unit 31 can.

Resin impregnation units It is possible1 to omit the resin container 8 and resin impregnation units of those shown in Figs. 4 and 6 instead Type to use. With reference to Yig. 4, R1 represents a powered resin impregnation unit which is generally an open-ended, tubular housing or a so-called. Canister 35 comprises, which has a vertical round cross-section and a relative has thick ring wall 36 with a central hole 37. The rings wall 36 is with a number of axially ii spacing including the circumference angeotduaton round plates 38 provided, which serve as power transmission units or so-called "Schallt @@ ber".

Each of the plates 38 is in turn with a suitable acoustic energy generating unit for generating the notin the manoeuvrable energy to put the resin in the housing 35 forward moving tubular member connected.

At each transverse end of the inner surface of the annular wall 36 is a neoprene rubber gasket 39 is provided with an inner diameter sufficient to accommodate the passage to enable a thread-wrapped pipe. From Fig. 4 it is evident that the Seals 39 have such a shape around the pipe. at its passage through the housing 35 to adapt. In addition, the seals 39 are sufficiently flexible to to give way and thereby non-linearities in the circular dimension of the through the housing 35 to receive continuous tube. The seals 39 are also sufficient stiff, around an engagement that is essentially tight against gaseous or liquid media between the surface of the tube and the interior of the housing 35. Although that between the outer surface of the pipe and the inner surface of the Ring wall 36 existing spacing was shown as quite large, this is used Illustration of the explanation of the invention. It should be noted, however, that this annulus has a considerably small thickness and that the outer surface of the pipe only at a very small distance from the inner surface of the wall 36 is.

The housing 35 is also with a pipe joint or with a built-in 40 and a hose 4o 'connected to a suitable source of liquid resin (not shown) connected is equipped. In this case it is possible to continuously supply a resin matrix to the housing 35. In the same way is the housing 35 is also provided with an upwardly extending hollow standpipe 41, that serves as an air collector. The standpipe 41 is with a removable cap or a removable lid 41 'and a sight glass 42 that extends over the greater part of the vertical length of the standpipe 41 extends. Air that has been introduced into the various fadeas branches is from the fluid Resin is displaced into the housing 35 when the strands come in. This air will normally pressed into the standpipe 41, where it displaces the liquid resin therein and after presses down.

The amount of displaced air that has accumulated in the standpipe 41 can be observed through the sight glass 42 from time to time. After yourself has accumulated a sufficient amount of air, the lid 41 'can be used for draining the accumulated air. When this is done, the standpipe becomes usually filled with the resin under pressure. It can be observed that within of the housing 35 always the same pressure conditions regardless of the amount of air, which has accumulated in the standpipe 41 can be maintained.

A touch resin impregnation unit R2 is in the vertical Sectional view of Fig. 6 explained in more detail.

The resin impregnation unit R2 generally comprises an open-ended, tubular housing 43 with a round vertical cross section and an annular Side wall 44 with a central bore 45. The housing 43 is with an annular Inner side wall 46, which is at a small distance from the outer surface of the tube passing through the bore 45 and thereby an annular space 47 forms in between. The housing 43 is also with a pipe connection or with a fitting 48 and a flexible tube 49 equipped with a suitable Resin matrix supply source (not shown). In the same way it is Housing 43 also with an upright standpipe 50 with a removable cap or Equipped with a removable lid 50 'for the collection of entrained air. The standpipe 5c is also with an @ichtgas 51 to observe the amount of Air that you have collected in it equipped.

At each of the transverse ends is the housing 43 with inflatable seals 5 and 53 provided. The construction of the seals 52, 53 is customary and can be designed with a Diise or similar valve structure for the creation be provided with a fine airtight seal.

The seals can be blown to match the hole through the hole 45 through tube engaged at a desired amount of pressure on the tube to get.

The rear seals 52 are generally with a low air pressure source inflated to an adequate pressure in the housing 43 to maintain and thereby a leakage of liquid resin to the outside by the seals 52 to prevent. The front seals 53 are pressure regulated, to get adequate resin deposition on the outside surface of the pipe.

When the seals 53 are inflated only with a small amount of pressure a rather thick coating of resin appears on the surface of the pipe. When the seals 53 were inflated to a fairly high pressure, get there they in the same way with the side wall of the housing 43 passing through The pipe engages with a fairly high degree of pressure and prevents its presence a resin-rich coating on the surface of the pipe as it passes through the housing 43. In addition, the seal 3 is used when it is on a very considerable Pressure is blown out as a kind of wiper and essentially supports the removal of part of the resin matrix that is on the outer surface of the pipe may be present.

It should also be noted that the seals 52 and 53 are also at the housing 35er with the resin impregnation force working unit R1 can be used can.

Apparatus in which resin applicators for manufacture be used by reinforced pipes.

A2 denotes an apparatus for the production of continuously wound thread reinforcement tubes for high performance purposes and is detailed in Fig. 5 explained.

The device A2 is essentially the device A1 with the Modification similar that the device A2 a number of resin application devices R1 is used in place of the resin container 8.

The device A2 generally comprises a base plate Go on one end of which is a bobbin frame or rack 61 with a row of them across extending spindles G2 for receiving common thread or roving bobbins 63 is attached. An eyelet 64 is provided for each of the bobbins 63 and the strands of thread 65 are passed through the eyelet 64 attached to each spool. These strands withdrawn from the spools 63 serve as longitudinal strands in formation of the endless hose. On the base plate 60 is an upright A-frame 66 attached, on the upper end of which a support 67 is attached. With the support is a mandrel 68 firmly connected, which is in the cantilever position extends and is substantially similar to the mandrel 14-66 Lich. Immediately after The frame in the advance direction is an upright support frame on the base plate 60 69 attached to support the resin application unit R1. From Fig. 5 it can be seen that many of the strands drawn from the spools 63 around the mandrel 68 out and passed through the resin application unit R1.

Furthermore, on the base plate 60 are two helical winding Winding points W1 and W2 attached, essentially with the winding points W1 and W2 of the device A1 are identical. From Fig. 5 it can be seen that each the winding points W1 and W2 upright coil support frame 70 for the reception of circular bobbin support plates 71 includes. Rotatable on each of the coil support plates 71 and extending outwardly therefrom from both of the planar surfaces Common roving bobbins 72 attached. The rest of the build of each these winding points W1 and W2 are in turn those in connection with above the device A1 described Widklungsstellen identical. It should be noted that the final ends of the process by eyelets or so-called "redirectd" to an end assembly, with the eyelets on any conventional Support structure are attached.

It can be seen that the application of the longitudinal strands and the two helical winding points) V1, W2 s the three-way combination of Forming winding elements as described above. The longitudinal strands are arranged around the mandrel 68 so that they envelop substantially the circumference of the mandrel 68. Moreover, it can be seen that these strands 65 passing through the resin application unit R can be saturated with the resin matrix contained in the housing 35. After that, the additional helical strands are attached to the winding points W1, W2 wound onto the longitudinal strands.

These helical strands tend to absorb a large one Amount of the resin-rich layer on the outer surface of the longitudinal strands. At this Connection point it is possible to attach another resin application unit R1, dS atf is attached to an upright support 73 which extends in the forward direction from the Winding point W2 is attached. If the type of tube to be formed or Rohres no further layers of longitudinal strands or spirals or strings requires a pair of circumferential winding locations similar to the winding locations W3, W4 of the device A1 for adding this final Circumferential winding to be provided on the continuously formed hose. It however, it can also be seen that an additional number of three component winding elements can be provided. For example, it is behind the resin application unit R1 possible, further longitudinal windings and then helical winding points to be attached similar to the points W1 W2. In addition, it should be noted that the resin application unit R2 is used in place of any or all of the resin application units R1 can be. In general, it is only necessary to have a touch resin impregnation unit Use R2 at the beginning of the Faddn application. However, if a number of three Component winding points is used, it is obvious that the to use power resin impregnation unit R1 to make a complete Ensure contact of all of the thread strands with the resin matrix.

The remainder of the device A2 is essentially the same as the rest Part of the device A1 is identical. Moreover, the operation of these devices identical in all other respects.

A device using an extruder or an extruder for the production of reinforced pipelines.

It can also be a modified form of tube or hose generating device A3 can be created, which is illustrated essentially in FIGS and is similar to device A1 described above. Device A3 is similar to device A1 except that device A3 has a Extruder or an extrusion press for the production of an essentially kiln or rigid tubular member used and therefore the need for a fixed mandrel carried on a support is avoided.

From Fig. 7 it can be seen that the device A3 in general comprises a base plate 80, on one end of which a bobbin support or a bobbin frame 81 with a series of transversely extending spindles 82 for the reception of conventional Roving bobbins 83 is attached.

A special eyelet 84 is provided for each of the bobbins 83 and thread bar 85 are passed through the eyelets 84 connected to each of the coils. The roving 85 used can be any of the endless shops as in context with the device A1 or A2 described. The different strands 85 are drawn through a carding plate 86, which is expediently provided with openings is to locate each of the strands 85 ..

The strands 85 are then passed over a roller 87 which is attached to a Resin container 88 is attached, this being attached to the bottom plate 80 in the manner shown in FIG. 7 is attached in the manner shown. The various strands 85 are spaced apart from each other in the transverse direction B over the roller 87 in a trough 89, which is a suitable contains liquid resin, passed. The resin contained in the tub 89 can be any of the liquid resins used in conjunction with the device A1 or A2 became. The strands are passed through a pair of pinch rollers 9o attached to attached to the opposite end of the tube 89 is the remaining part; of Resin container 88 is essentially similar to that described above in connection with the apparatus A1 described container the same.

A conventional extruder or is also on the base plate 80 a conventional extruder 91 attached, which is used for the extrusion of plastic hoses or lines is formed with the desired cross-sectional shape. In the The production of transport pipes or lines for liquids or gases is that Extruder equipped with a head 92, which is used for the extrusion from Plastic pipelines formed with a circular cross-sectional shape is. In the event that an extruder of a considerably large amount is used, can the extruder can also be placed after the resin tank 88. With this type of training the resin container 88 may differ slightly from the location of the extruder or opposite the extruder assembly may be offset slightly, with the various strands 85 across Pulleys (not shown) are guided if desired. Any suitable Plastic material can be used. The kind of materials that according to According to the invention, polyvinyl chloride, styrene and styrdi-butadiene copolymers can be used It should be noted that these molded or extruded pipes have a should have sufficient heat resistance to safely pass through the hardening zone, wherein the wall structure of the pipe is melted or polymerized will. At relatively high curing temperatures, various materials, such as fluorine films, i.e., tetrafluoroethylene films, polyphenylene oxide films, numerous of the modified Po19 carbonate films and the like, can be extruded Note that this extruded pipe or hose material does the job the formation of a in situ mandrel serves, the need for one completely excluded. Although at the device A3 does not use a solid mandrel carried by a support Nevertheless, it can be seen that a solid mandrel (which is connected to the tubular Link not moved) is used. This solid mandrel is actually in the extrusion form present and actually serves as a solid mandrel. Also the extruded unit serves as a thermoplastic, seamless lining. It should also be noted that when the working speed of the winding components as described below, and the extrusion unit vary enough Bt8 to operate properly (in-line oparation) to prevent the thermoplastic or extruded tubing Tubing from the extruder 91 into the filament winding part of the machine in individual Lengths can be guided. In this case the ends of each length are from the extruded tubes in the adjacent layer, and the continuous in-situ mandrel to surrender.

With a view to reducing the overall length of the device AD a conventional right angle extruder can be used.

The remaining part of the device A) can essentially the Device A1 or device A2 may be the same or similar. On the baseplate 80 is in the advance direction from the extruder or extruder 91 Pair of helical winding winding points W1, W2 attached, which essentially the winding points T1 and W2 described above, as in the Yorrichtung A1 used are the same. It can be seen that when the plastic tube is removed from the Extruder 91 is pressed out, the longitudinal strands 85 through a carding plate 93 drawn and arranged around the liner so that it is essentially the Wrap around the circumference of the lining. After that, the lining is placed with the ones placed on it Longitudinal Cträngdn passed through the two winding points W1, W2, with the reverse mutually arranged helical or spiral strands around the lining to be wrapped. At this point, a pair of circumferential winding points W3 and W4 are provided, which essentially correspond to the winding points W3, W4 in the Device A1 are similar. When creating another combination of three of winding points is desired, d. H. the longitudinal strands and the two spiral winding points W1, W2, is the application of a R1 power unit or resin application unit the contact resin application unit R2 is expedient. In any case, it is to be expected that the Longitudinal strands 85 are sufficiently saturated with a liquid matrix are so that subsequently applied windings are also a sufficient amount absorb on liquid matrix. A hardening zone is also used in the same way. The remainder of the device A3 is essentially the device from then on A2 or A1 is the same.

The application of this relatively thick film made of plastic, which serves as a lining is particularly useful in the manufacture of thick-walled pipes or lines usable. In the production of thick-walled pipelines can the use of a number of consecutive winding points and / ò the resin application units cause a considerable extension of the device. When applying one through one Supported solid mandrel, this mandrel remains a structural support for everyone and all of these subsequently applied layers and would become apparent the mandrel have a considerable length.

This could also lead to high frictional loads during pulling guide the uncured product along and off the mandrel. About these high frictional loads release, and the same amount of energy in the order of magnitude of PS used to pull the pipe along a well with full Length is required to keep, the application of the extrusion proved structural lining as a very useful aid.

Device for the production of reinforced hose or pipe materials with a welded lining. A device A4 for the production can also be used created by thread-reinforced pipe or hose materials with an inner lining which is essentially indicated in FIGS. 9 to 11. The pre-alignment A4, which is similar to device A1, generally includes a base plate 95. On one end of the base plate 95 is a reel stand or reel rack 96 a series of transversely extending spindles 97 for receiving common ones Roving bobbins 98 attached. A special eyelet 99 is provided for each of the coils 98 and the strands of filament loo from each of the bobbins 98 are passed through the with each bobbin associated Osea 99 led. The various loo strands are put in a resin container 101, which is essentially identical to the resin container 8. lus Fig. 9 it can be seen that the resin container lol is also on the base plate 95 in Forward direction from the spool rack 96 is attached. In addition, the resin container includes lol all of the Roles that are present in the resin container 8 are. The strands of thread used in any of the devices A1 to A3 can also be used in the device A4. In the same way can be any of the resin matrix materials used in devices up to A3 will also be used here.

In the direction of projection of the Hars container 101 is on the grand plate 95 an upright A-frame 102 is attached, on the upper end of which a support 103 now carrying a forwardly extending mandrel 104 in a boom position is attached. The mandrel 104 can have and is the desired cross-sectional shape substantially the same as mandrel 14 in device A1.

Also on the base plate 95 in the projection direction of the A-frame 102 achnecke-shaped winding points W1, W2 are present, which are essentially the helical winding points are the same in device A1 There can also be additional winding points, for example the circumferential winding points W3, 14 of the device Ii are applied. It can be used in any combination Winding points are used to create the desired wall structure and the to obtain the desired wall thickness. If more than a combination of three of one Pair of helical winding points and Longitudinal strands can be applied, the use of the resin coating units R1 or R2 be desirable.

On the base plate 95 is any conventional support structure a Um @ icklungsrohr 106 or a so-called. "Forming chute" (forming chute), often as "Forming shoe" means appropriately attached like this is illustrated in more detail in FIG. The wrap-around tube 106 is about its longitudinal axis curved and is initially formed from a flat sheet of metal. The grain radius not progressing in the direction of the longitudinal axis of the tube 106 down to an outlet opening 107 to form. Like from Fi. 9 as can be seen, the right end of the tube is only slightly curved and essentially forms a receiving trough 108, which is also is curved in the downward direction. With advancing. Distance along from the pipe 106 at its left end the longitudinal edges are curved upwards and inwards in such a way that because # the pipe forms a surface of revolution or revolution, its circumference and radius with further progress along the L. narrow axis decreases. The two long edges of the tube 106 are curved upwards until they only pass through a small distance are separated and are then in the stop upwards in the form of a pair of spaced apart opposing, upright extending flanges 1o9, which are separated by a longitudinal slot I1o.

It can be seen that at the point bpi wecher the tube with the upwardly extending flanges 109 is the diameter of the tube is slightly larger than the diameter of the mandrel 1o4. The tube 106 can also be formed ground by molding the same from a sheet of metal or it can be made of plastic be formed in any conventional molding process. A pair of nip rollers or so. "Hemming rollers" (not shown) can also be provided and can be attached at an angle to a sheet-like plastic material (described below) to wrap the mandrel 105 tightly.

The top half of the left end of the tube is for the inclusion a pair of metal plates 112 forming a bracket 113 which in turn is operable is connected to a sound sealing or sound welding device 114, removed. The device 114 is in use in its construction and it is therefore not explained in detail.

However, the plates 112 are the same size and shape as the part of the tube 106 that has been removed and moreover they are arcuate with Walls provided in a similar stand-up fashion. upright flanges.

It can also be seen that sealing or welding devices, For example a heat welding unit or a bonding iron can be used to seal the longitudinal edges of a plastic film or to weld.

Also on the A-frame 102 is a spindle 115 for rotatable support a spool of oriented plastic film or sheet-like plastic material 116 attached in the usual width. The film 116 is through the tube 106 of the right end in the manner shown in Figures 9 and 10. Thereafter becomes the film 116 for wrapping the mandrel 104 as it passes through the tube 106 brought. It can be seen that when the plastic sheet loG is drawn, the longitudinal edges W of the film in T + in accordance with the cross-sectional shape of the tube 106 are bent. In addition, the longitudinal edges of the plastic sheet extend into the longitudinal slot where between the pair of upright flanges 109.

When the welding or sealing is operated, it is heated the upper longitudinal edges of the plastic web are welded or sealed around the mandrel 104, thereby forming a plastic liner around the mandrel. on the other hand can overlap the longitudinal edges Arrangement brought and in be welded in this way.

Some of the plastic films that are related to use for are suitable for this embodiment according to the invention, are some of the mini-copolymers, for example vinylidene fluoride. The films used in this context are different plastic materials, for example polyphenylene oxide, Polysulfones and some of the modified polycarbonates, chlorinated polyethers and some of the fluorine-containing polymers (f-luorics), zlB. Polyvinylidene fluoride. These The latter materials must of course have sufficient heat resistance, to be safely guided through the hardening zone in which the tubular structure wall melted or polymerized. With regard to the relatively high curing temperatures, for example from about 1770 C (35o0F) and above are the various halogen-containing Films (fluoric film), for example Tetrafluoräthy len (tetrachlo @ ethylene) and the polyphenylene oxides, the polysulfones or the like are very effective.

It has been found that the lining material can be chosen in this way can, because # it has the effect of corrosive liquid or gaseous media or abrasives, which are to be applied in the finished lines, resist very effectively can. In addition, these linings serve also as a kind of heat-insulating partition. The lining wrapped around the mandrel is then through the various winding points, for example, the points W1, W2 directed. The longitudinal strands are passed through a carding plate 117 and Applied to the clothing in such a way that it covers the circumference of the lining in front of the leg insertion wrap the insulation in the first winding point W1. This structure is in Fig. 9 explained in detail. It can thus be seen that the final formed The pipe material essentially corresponds to the pipe material formed on the device A1 with the modification that there is a liner on the inner surface of the pipe was formed. The remainder of the work flow is essentially related to that with the device A1 described part the same.

Device for the production of reinforced pipe or hose materials by forming an in situ mandrel on a solid mandrel.

It can be a device A5 for the production of thread-reinforced Pipes are created which is similar to the device An with the modification that an in-situ mandrel is formed around the fixed mandrel and then wound on the in situ mandrel is carried out. the Device A5, which is in Illustrated in detail in Figures 12 and 15 generally comprises one Base plate 120. In addition, the device A5 comprises a reel stand or a Spool rack (not shown) similar to the spool rack used in the device A1 2. Ditser stand naturally has the facilities for accommodating the usual ones Roving bobbins in order to extend thread strands 121 from each of the bobbins. The different Strands 121 are fed into a resin container 122 which is located on the base plate 120 is attached in the manner shown in FIG. The resin container 122 is again the resin container 8 used in the device A1 is essentially the same the container 122 is of the same type of roller structure or arrangement equipped as it was used in the container 8.

In addition, 1Bo is on the base plate at a distance in the projection direction An upright A-frame 123 is attached from the resin container 122. On the top The end of the A-frame 123 is a support 124 for supporting one in the forward direction erecting mandrel 125 attached in a cantilever position.

In addition, is on the base plate 12o at a distance in the projection direction to the A-frame 123, a wrapping tube or a forming shoe 126 attached, the substantially the above-described molding shoe 1o6 the Device A is similar. Wrap tube 126 is also 4 in its longitudinal axis curved, around a receiving trough 127 at its right end and an ejection opening 128 at its left end to form. As shown in Fig.

12 can be seen, the longitudinal edges with increasing distance of the pipe 126 to its left end up and inward of curved that the tube a Orbital or rotating surface forms the circumference and radius of which as it progresses along decreases from its longitudinal axis. The two long edges of the tube are upward in Shape of a pair of upright stop flanges 129 curved through a Longitudinal slot are separated. moreover is part of the upwardly extending Remove flanges at the left end to create a color of metal plates 130 form a bracket 151 to receive. The bracket 131 is in turn operationally with connected to a sound sealing or sound welding device, or he can also be done with another common sealing or welding mechanism (not shown) connected.

However, this device is common in its construction and is therefore not explained in more detail. A pair of pinch rollers 131 '(not shown) can also be provided. The rest of the structure of the Formunesrxhres 126 and the The sealing or welding device is essentially that of the device A4 used the same.

Also on the A-frame 123 is a spindle 152 for rotatable support a spool of plastic film or sheet 153 is attached. The railway material 133 is inserted into the wrapping tube 126 in the manner as shown in Fit. 12 shown guided. It can be seen that as the web is passed through tube 126, the longitudinal edges of the path 133 curve in accordance with the cross-sectional shape of the tube 126. In addition, the longitudinal edges of the plastic sheet extend into the longitudinal slots, which are present between the flanges 129. When actuating the sealing or sonic welding unit and the plates 130 become the upper longitudinal edges The sheet of plastic is welded or sealed, making the sheet of the mandrel 125 practical redesigned.

In the forward direction is spaced from the wrapping tube 126 the base plate 120 also an upright support frame 134 attached to his upper end of a hardening in @@ it 135 holds. From Fig. 12 it can be seen that the hardening unit openings are suitably provided to both the mandrel 133 and the Plastic ban read wrapped around it. Of the Film 133 is preferably made of a film or material such that in one rigid state in the hardening unit 135 can be polymerized or solidified. In addition, the unit 135 is designed to match the type of plastic sheet 133, which comes into effect, is contractually the ilm 133 can be made up of a reinforced Plastic mat are made with crushed glass and can be impregnated with resin be that the latter is in the A or B stage. When inserting into the hardening unit 135, however, the resin can be fully cured or up to its C-level advanced. Some other materials than plastic material 133 are had or frames made of "C-glass", long asbestos staple fibers, synthetic fibers of polyamide, polyester or the like. The resin binder disclosed in this material can be included, can stick out of such resins, which are used to Use in ddr resin application devices and resin containers, as described above, were chosen. However, this can also be the case with this particular turn H2ize, such as bisphenol A / fumerate, bisphenol A / acrylate or the like, can be used.

Also is on. of the base plate 120 at a distance in the forward direction attached to the hardening unit 135 a pair of winding points W1, 2, which in essential the in any of the apparatus described above A1 - A4 used winding points W1, W2 are the same.

These winding points W1, W2 can in turn be helical or helical winding places or spiral winding places in desired To be wise. It can also be seen that the longitudinal strands 121 are passed through a carding plate 136 and introduced at points in front of each of the winding points W1, W2. Accordingly, the first triple combination of longitudinal strands became helical strands and a second layer of helical strands in reverse described in connection with the device A4. It is to be bemen that additional Combinations of three development points can be used. aside from that note that any number of circumferential winding locations if desired Can be applied to the desired wall structure and thickness to obtain. In connection with the device A5, however, it can be seen that only a relatively short one at the front 125 is used. Before the first combination of three of winding points, the film 123 is hardened to form an in situ mandrel, around which the further wrapping is carried out. The film 133 does more than just serve as an in situ mandrel, but also as a liner in the finished tubular Product.

It should be noted that any of the resin application units R1 or R2 also instead of the resin container 122 or in addition to the resin container 122 can be applied if a number of three-combination winding locations should be applied. When the length of the entire device is increased to A5 it may be appropriate to place some of the fiber strands in front of a final hardening unit to impregnate again. In the same way, the device A5 also includes a hardening unit, which is similar to unit 24. In addition, the device also includes a pulling unit, which is similar to unit 31. Essentially the remaining part of the building or the structure of the device A5 practically that in connection with the device A1 structure is the same. Moreover, the method of application is different from everyone these devices then do the same.

Device for the production of reinforced pipe or hose materials with an inner lining in the dough. 14 and 15 is another embodiment the device and the method according to the invention for the formation of tubular Products with an inner lining explained. The ones in jig. 14 shown device A6 is essentially the device A1 and the device with the deviation similar in that the longitudinal edges of the Film cannot be welded and the i'ilm is neither polymerized nor hardened. The device A6 comprises generally a base plate 140. Device A6 also includes a reel stand or a bobbin rack (not shown, which is attached to the bobbin rack 2 in the apparatus A1 and normally includes the bobbins of roving on the bobbin. Individual strands 141 from each of these coils on the rack are passed through a Resin container 142 drawn, essentially the resin container described above 8 is the same for the device A1. moreover, the resin container 142 normally comprises all of the various roles that exist in the resin container 8. Besides can see the different types of roving that can be used with the device A1 and the various liquid matrix materials which can be used in the container 8 are also used in device A6.

On the base plate 140 is also at a distance in the foreword direction An A-frame 143 is attached to the container 142.

A support l44 is to protrude on the upper end of the A-frame 143 a mandrel 145 extending in the forward direction in the manner as shown in FIG. 14 shown attached.

The mandrel 145 can have a round or non-round cross-sectional shape have the desired manner.

On the base plate 140 is also by means of any suitable A wrap-around tube 146 is attached to the support structure, which also extends around the mandrel 145 and is similar to the wrapping tube 126. Essentially it does Wrap tube 146 is the same as wrap tube 126 except there it uses the sound mechanism or another welding device for welding 3rd longitudinal edges of a plastic sheet does not have. On the A-frame 143 is also etne Q2indel 147 for the appropriate collar of a roll of plastic film or a plastic sheet 148 attached. The plastic sheet used in device A6 148 is the same as the plastic web 116, which is used in the A4 device. In many cases it is not necessary to weld the longitudinal edges of the plastic sheet, as it was carried out for the plastic sheet 116 in @orrichtunbg A4. These Kind of device like A4 leaves a light seam along part of the side wall the lining.

In the device A6, the tube 146 is curved in such a way that a longitudinal edge of the plastic web 148 over its longitudinal edge lying opposite one another in FIG Overlap of the arrangement is folded. It is also within the scope of the invention a common application device for glue or binding agent for fastening of the upper edge of the plastic gauze on the edge of the plastic sheet, the one underneath is to be used in direct edge alignment by means of adhesive force.

There is also a pair of helical winding points on the base plate 140 W1, W2 attached, which essentially correspond to the helical winding points W1, W2 in the establishment A1 are the same. It can also be seen that the longitudinal strands 141 through suitable eyelets 149 and suitable deflectors 150 are passed around the strands 141 on the liner thus formed in a suitable position before the liner passes through the first winding point W1, becomes a series of longitudinal strands 141 applied to the lining so that the longitudinal strands 141 substantially envelop the circumference of the liner. When the lining with the longitudinal strands thereafter passes through the first winding point W1, becomes a first layer applied to them by snail-shaped austerities. Then a the second layer of the helical strands in the opposite direction Liner and the windings so formed are applied. moreover, as in Hig. 14 ', it is also possible to have an additional layer of longitudinal strands in front of the second winding point W2 to apply.

It can thus be seen that the triple combination of windings in turn is provided. The embodiments described in each of the above According to the invention, it is possible to have additional three-way combinations of winding points or any spiral winding points circular winding points to end in the desired manner. In turn, the type of development points used and the number of winding points used by the desired wall construction and determine the desired wall thickness of the final pipe.

Device for the production of reinforced hose or pipe materials by forming a thread-wound in situ orne. Another modified form can be used a thread winding device A7 illustrated in FIG and is similar to device A1. they device A7 differs from of the device A1 in that a relatively short mandrel is used and this mandrel is only used to pull a pipe wound with thread material to form, which is finally cured there in order to then serve as an in-situ mandrel.

The device A generally comprises a base plate 7155 one of which is a bobbin rack or a bobbin rack 156 with a number of spindles 154 extending in the transverse direction for accommodating common Roving bobbins 158 is attached. There is a special eyelet for each of the coils 157 159 is provided, and the strands of filament 160 are connected through that to each spool Eyelet 159 guided. The roving that can be used with device A7 is the same as the çorga used in any of the devices described above was used.

Each of the thread carriers 160 is through a carding plate 161 and in a resin container 162 is passed, which is placed on the base plate 155 in the manner as in FIG Fig. 16 is shown attached. Resin container 162 is, in turn, essentially the resin container 8 described above and includes all roles, which were connected to the resin container 8. Moreover, the one that can be used here is liquid Matrix the same as any of the liquid matrix materials included in any of the devices described above was used.

On the death plate 155 is longitudinally spaced from the resin container 162 an upright A-frame 163 rigidly attached to the A-Rafimen 163 is a support 164 for carrying a forwardly extending mandrel 165 in a Boom position attached0 The mandrel 165 is the mandrel 14 in the device A1 similar and may or may not have a round cut. Furthermore is on the bottom plate 155 a carding plate 166 is attached, with by spacings separate openings for the alignment of the longitudinal strands 160 on the front 165 are provided is. In essence, the openings are located so that the strands 160 be deposited on the mandrel 165 in such a way that they essentially envelop the circumference of the Xorn 165.

On the bottom plate 155 is also spaced in the forward direction a pair of helical winding points W1, W2 are attached to the A-frame 163, essentially the winding points W1 described above in the device A1 are the same. The first winding point W1 is designed to be first Apply a layer of helical windings to the longitudinal strands, and the second winding point W2 is designed in such a way as to have a second layer of helical windings in the opposite direction to that of the Place W1 to apply. Off able. 16 it can be seen that the mandrel 165 is snch in a suitable curing device 167 extends substantially in the direction of curing 24 is the same in device A1. The hardening device 167 is expedient attached to a frame 168, which in turn is attached to the base plate 155. The curing unit 167 is preferably an "R-F" heating unit and operates in the same way as the hardening unit 24.

It can thus be seen that the three-way combination of winding points, the application or application of longitudinal strands and of two types of helical Strands at the points W1, W2, forms a sufficient wall thickness. moreover if these strands received a sufficient amount of resin from the longitudinal strands l6O, by the resin container 162 were guided. Because this combination of door yarn passes through the curing unit 167, it is cured and forms a substantially rigid tube. This pipe then serves as a in situ mandrel.

It can be seen that the mandrel 165 ends at the curing unit 167.

It is now possible to have a number of additional three-way combinations of winding points, if desired. The location shown in FIG Wg illustrates the first helical winding point of a second combination of three. It can also be seen that longitudinal linings directly on the pipe thus formed in front of the winding point W3. So these become snail-shaped Strands applied to the tube so that they essentially envelop the tube. After that, at the first winding point, this new three-way combination will be new Helical windings applied.

It should be noted that every type of winding point and every combination can be applied from these locations after the formation of the initial tube. The type of winding points and their respective local definition wiid of course from iem g @ wänschten wall structure of the finished pipe and the desired thickness certainly. This type of in-situ thorn formation was found to be most effective in the case when a number of three combinations or winding positions are found proved necessary to a relatively thick pipe wall too form.

The remainder of the device A7 is essentially the device A1 is the same and usually includes a pulling unit, etc. Moreover, the method is the operation of the remaining part of the construction of the A7 in the main of those the device A1 is the same.

Device for laying out pipes or lines from one itself moving vehicle or vehicle Each device A1 to A7 was found to be special effective in the continuous laying of lines or pipes from one itself moving carrier or vehicle.

For example, these devices can be used in the continuous Formation and continuous laying of pipes under water from one disembarking or continuously shaping and laying pipes or lines above ground or underground by a motor vehicle or the like. A device A8, which essentially Each of the devices A1 to A7 is the same, conveniently placed on a ship B. be like this in sig. 17 with parts removed. The ship B is generally with a relatively deep cargo space 170 for the reception the device A8 in the in sig.

17 provided in the manner shown. The ship is at his Bow end provided with a trap door or a flap 171, lim the removal of the line from ship B. At its stern end the ship is with a common Structure or wheelhouse 172 (helm) essentially the same as that of the present Type of ship used for laying undersea cables. It is note that the ship B is moving astern so that the tube is continuous is withdrawn and laid down by its bow.

According to the invention it has been found that it is possible to use pipelines from ship B at a rate of about 1.2 to 2.1 (4 to 7 feet) per minute in Depending on the pipe diameter and the desired wall thickness to form and to interpret. The hold of the ship B is preferably covered with a cover 173 covered to a disruption of the working conditions of the device A8 by a salt spray to prevent. In addition, it is desirable in many cases to use conventional dehumidifiers to use in the storage room of ship B to ensure the appropriate working conditions to obtain.

The device A8 similar to the device A1 generally comprises a creel or a bobbin rack 174 with common roving bobbins for kneading out individual strands of roving 175. These strands are passed through a resin tank 176, which is similar to the resin tank 8. As in Fig. 17 shown can have four winding points W1, W2, W3 and W4 for Application. These winding points are essentially the respective winding points W. to W. in the device A. the same. In addition, one of the hardening units 24 becomes similar hardening unit 177 is used. After this, a pulling unit 178 is also used which is similar to the pulling unit 51 is used.

It can be seen, however, that in connection with the device A8 it is necessary to have a braking unit 179 dwell. The braking unit is also attached to the hold of ship B in alignment with the other components of device A8 $. The braking unit can be of any conventional construction and, if desired, is to ensure that the tubing is not pulled from the mandrel due to the forward movement of the ship B or the hanging weight of the completed tube at too high a speed. The ship B is preferably equipped with a device for adjusting the Center 180 of the type commonly found on ships used for cable laying operations. These centering or position setting devices generally comprise three or more meters, which should be arranged with a deviation of 1200 and mounted on a frame so that they can be moved. The raw material or conduit material formed in the ship B is pulled by each of the three rollers at the point of discharge from the ship B. Moreover, this structure is movable in order to overcome any uncontrolled vibration or displacement of the ship B. Thread-reinforced pipelines that are laid underwater have several distinct advantages that adhere to the construction materials. Pipelines of this type are corrosion-resistant and light in weight. Moreover, since the apparatus A8 can make pipelines on a continuous basis, the usual problem of connecting pipes is eliminated. In addition, the pipe or line material has a weakly negative buoyancy factor, expressed in minimum resting load, when it is filled with liquid and placed on the bed of a body of water. Thread-reinforced pipelines, which are produced by means of the device A8, also have greater flexibility than the usual steel and metal pipes, this being due to the relatively low modulus of elasticity of the thread-reinforced pipelines. In general, the modulus of elasticity is approximately 15 × 10 6 to approximately 2. As a result of this low modulus of elasticity, the filament-reinforced pipelines according to the invention carry almost continuous cyclic bending reversals within approximately 8 to 10 ° amplitudes without fatigue.

In the manufacture of high-performance underwater pipelines it is expedient to have at least four ticketing points, as shown in FIG. 17 use.

After this networked untoroinanor vcrmisohto Layers of longitudinal filaments and a pair of opposing helical turns are deposited on the mandrel, a pair of opposing circumferential wraps are subsequently deposited onto the outer surface of the layered material thus constructed.

A second longitudinal winding is made between the pair of opposite ones helical windings and a third longitudinal winding is between the pair applied by opposite circumferential windings. Hence it finally owns tubing produced a first layer of longitudinal strands, a second and a third layer of opposing helical windings, a fourth layer of longitudinal strands and a fifth or sixth layer or even more layers of opposing helical windings. In addition, the pipe material an additional layer of longitudinal strands and additional layers of outer circumferential windings exhibit.

This type of tubing has been found to give superior results when used in underwater operations.

Device for the production of structural or structural shapes.

The device according to the invention is readily suitable from made for the manufacture of tubular sections with non-circular ones Cross-sections. For example, mandrels can be rectangular or trapezoidal Cross-section can be used, wbei tubular sections are formed, which in the essentially have a shape similar to the shape of the mandrel. The uniqueness and flexibility or versatility of the device according to the invention is impossible an economical and effective production, for example of thread sales markets Conductor rails on a continuous basis.

At the moment the majority of the ladders are made of wood or Solder metals, such as aluminum. Wood quickly loses much of its attraction and becomes an undesirable material for building ladders in so far as wood is a tendency to deteriorate rapidly upon exposure to weather conditions has, even if wood with a protective coating against the effects of the weather is overdrawn in advance. In addition, after-aging can occur while has started a certain period of time, the user of the device, if necessary Be subject to injuries from slate or splinters. Aluminum and others Similar building materials are due to their electrical conductivity properties disadvantageous. In general, most nonprofit companies make fiberglass or fiberglass Wooden ladders or scaffolding. This is particularly the case with non-profit operations in the electrical or telephone sector, with people using the ladder come into contact with high voltage sources.

This led to the emergence of fiberglass reinforced conductors, however there is currently no economically feasible process for production of the elements that form part of conductors, using fiberglass as the building material is used. As a result, conductors are currently made of fiberglass quite expensive and their use is limited to various non-profit establishments, whose staff can come into contact with electrical energy sources.

A device A9 for the production of structural shapes on continuous The basis is illustrated in detail in FIG. The device A9 comprises im generally a base plate 190, on one end of which a slip-on gate or a Coil rack 1? I with a number of them transversely extending spindles 192 for the support of common roving bobbins 193 is attached. A separate one Eyelet 194 is provided for the bobbins 193 and thread strands 195 are from each of the coils 193 passed through the eyelets 194 connected to each of the coils.

A resin container 196 is also mounted on the base 19o and is substantially similar to the urine container @ of the device A1. Also includes the, resin container 196 the entire roller assembly contained in the resin container 8 is. The same thread material and resins used in device A1 are applicable, can also be used in the device A9.

On the base plate 19o is also in the forward direction vdtn the resin container 196 an upright A-frame 197 is arranged. On the top of the A-frame 197 is a support 198 for supporting a forwardly extending mandrel 199 attached in a boom position. The mandrel 199 can be attached to the bearing 198 attached in any conventional manner. moreover, the thorn can do any have desired cross-sectional shape.

When manufacturing structural or structural elements, the mandrel has generally a non-circular cross-sectional shape. For conductor rails possesses the thorn im generally a rectangular shape of the in Fig. 19 shown type.

Moreover, 19o is spaced in the forward direction on the base plate attached to the A-frame 197 a pair of circumferential winding locations W3, 74, the essentially the winding points W3, W4, as used in the device A1, are the same. It should be noted that the mandrel 199 passes through each of these winding locations W3, W4 he stretches. The mandrel 199 also serves as the one that delimits the inner surface Cement for the endless pipe material that is produced from it. In addition, the The mandrel can be coated with tetrafluoroethylene polymer (Teflon) to reduce friction to reduce while pulling the endless pipe or hose material on it.

A carding plate 200 is also attached to the A-frame 197, around the longitudinal strands 195 on the mandrel 199 in place of the application of the round ones or to steer circumferential strands at the first winding point W3. It can be seen da # the three-way combination of winding positions used in this type of device used the longitudinal strands followed by the first set of circumferential strands at point s and the second set of circumferential strands at point W4. The circumferential strands at the site are applied in a direction corresponding to that at the point W3 is opposite. It should be noted that this type of winding combination is preferred in the manufacture of conductor rails. In the manufacture of others Structural or building elements with non-circular cross-sectional shapes can be as however, it may be desirable to have helical windings instead of or in addition to apply to the circumferential windings. Moreover, it may be useful to have any Use combination of these windings.

In the production of the conductor rails, as they are for example the As shown in Figures 18-22, it is convenient to use a series of longitudinal strands to apply to each of the mandrel's four corners / so on the mandrel that substantially in these strands overhang or overhang the corners in the manner shown in FIG. Circumferential strands are applied to the winding point W3 until a structure is similar that shown in Fig. 2o is obtained.

Subsequently, additional longitudinal layers are applied to both the upper one as well as the lower surface of the mandrel and each of the side walls. However, a much larger number of strands will be applied to both the upper and the upper also applied to the lower wall than to the side walls, to the extent shown in FIG structure shown.

Finally, circumferential strands are added at r additional circumferential winding point W4 upset. In the manufacture of conductor rails it is necessary to be proportionate thick front or end walls connected by relatively thin side walls are to be had, since the end walls bear the much larger part of the load. Accordingly, the end walls are covered with a fairly thick layer of oil strands educated. If desired, one or more additional layers of circumferential strands can be used can be applied by means of further winding points (not shown).

The conductor rails are through a unit 201 for smoothing or Adjusting the size pressed into dough. 22 is explained. This unit is mounted on the support frame 202, which is mounted on the base plate 190 in the manner shown in FIG. 18 is attached in the manner shown. The sizing unit 201 generally comprises 4 stripping shoes 203, which are attached to the inner surfaces of the rectangular unit 201 forming four walls, are fixed in the manner shown in FIG. The four Rectangularly attached scraper shoes 205 have flat inner surfaces 204, the one with the outer surface of the tubular member formed on the mandrel 199 will, engage and smooth the surfaces of the outer walls of the tubular Link and to remove irregularities in the rare to serve, so that the walls are essentially flat and level. However, it should be noted that the corners of the tubular member are still rounded.

The conductor rails are hardened in a hardening unit 205, which are also mounted on the support frame 202 in the manner shown in FIG is. The hardening unit 205 is essentially the hardening unit 24 in the device Similar to A1, except that the electrode through which the tube passes is non-circular is as described below. It can also be seen that the The mandrel extends through the hardening unit 205 and at the opposite end thereof ends.

On the support frame 202 is spaced in the forward direction from the curing unit 205 also brought a pulling unit 206, which is also essentially the pulling unit ; 51 in device A1 is similar. The pulling unit 206 necessarily has a sufficient pulling force to reduce the friction of the tubular formed on the mandrel 199 To overcome limb. A common grinding edge disc saw or so-called "circular saw" 207 is attached to a mobile ion trestle or a sliding Trsnsrortwagen 208, which in turn is slidably mounted on the support frame 202 to the formed Cut the pipeline to the required length. These lengths are obvious to the Formation of conductor rails suitable. It is also possible on the support frame 202 a common drill or drill mechanism 209 for the selective drilling of openings in the side walls of the ladder rails for the introduction of ladder rungs (not drawn). It should be noted since the drilling mechanism 209 is also mounted on a sliding assembly stand 210 is, which is displaceable on the support frame 202 in the longitudinal direction. The drilling mechanism 209 is preferably equipped with an indexing probe, which engages previously drilled holes in the conductor rail for adjustment or classification of the appropriate location arrives to the drilling of the next 'neighboring Set of holes.

209 Both the saw 207 and the drilling unit are standard accessories and are therefore not explained in more detail.

207 It should be noted that the saw and the drilling unit 209 are mutually exclusive for selected lengths according to the extent of movement of the formed-20hr material In essence, each of these components moves forward, i.e. in Fig. 18 to the left for a selected distance until the operation is completed and then moves back to its current initial position on the right Page for the beginning of a new work cycle. These components include even positive, successive automatic, adjustable to the corresponding speed Switch-off points and common circuits for limited switch actuation. It is also possible to use a run-out table (not shown) that has a larger one Can accommodate length of separately cut sections of piping. This The table is inclined slightly perpendicular to the axis of the pipe or hose material, around a natural stratification or stacking and accumulation of separate lengths to bring about. This practically sets the process in motion made possible without monitoring for long periods of time.

The hardening unit 205 also consists of a radio frequency hardening unit or sound hardening unit.

However, instead of the aluminum pipe section 26 in the hardening unit 24 uses a rectangular shaped tubular member 211 and serves as the one electrode while mandrel 199 serves as the other electrode. It also smooths the element whose inner surfaces are flat, the surface of the tubular Member during its hardening.

The electrode 211 can also serve as a squeegee 203, thereby avoiding the need for the smoothing unit 201.

In addition, a support table 212 is attached to the base plate 190, on its upper end an application device 213 for applying adhesive labels or labels attached. The application device 213 includes a roll of with Resin-impregnable paper stickers or labels and a roll that is continuous the strips of sticky notes or labels on the side wall of the formed The pipe. The application device 213 for applying adhesive labels or labels can also be applied to a mobile assembly stand in order to achieve a Get movement with the conductor rail for certain distances. This kind of Device usually includes a pair of pneumatically controlled arms (not shown) taking a label or a stick-on sticky note from a stack of each separate sticky notes or labels and attach them to the side wall of the Ro @ res that is formed moves.

This mobile Nontagebock ve pushes in tact-wise ratio z the movement of the pipe material on the mandrel 199. From Fig. 18 it is replaceable da # the application device 21 @ for applying labels or sticky notes iot attached between the winding points W3 and W4, so that the label or the glue-on time is applied before the final circumferential winding is wrapped will. In this case, the stick-on note or label is always surrounded by an external one Resin impregnated glass cover protected. Moreover, the label is or the sticky label is always clearly visible, as the thread material wetted with resin, that is used can be transparent.

In some cases it may be desirable to have a jacketed heating zone (not shown) in which the conditioned heat is applied to the tubular Limb is held at approximately 93, -3 ° C (200 ° F). This other type of unit can be in some cases it may be useful and desirable to prevent thermal shock and eliminate any latent exothermic overheating. Besides, you can Allow hardened tubing to traverse an open area to another To facilitate cooling prior to entering the pulling unit 206.

The finally completed structure of the conductor rail is the im Similar to the structure shown in FIG. 21.

It should be noted that in order to obtain the relatively thick end - or End walls or so-called end caps "(" caps "), adjustment or bearing rings for use can get to lay the longitudinal strands on the mandrel in the desired position. It should be noted that the strands overhang the end walls up to the side walls or cantilever to make relatively short edges of thickened areas on the Sidewalls to accomplish. The circumferential windings make up most of the inner surface the conductor rails and are, as described above, through the winding points W3, W4 formed. Only the fiber materials extending in the longitudinal direction are impregnated with resin and the circumferential strands are in the dry state Applied. Experience has shown that with resins of suitable viscosity alternating Layers of resin wetted and dry strands uniform and complete can be thoroughly impregnated almost instantly. Through this arrangement -will the need to carry more resin baths with the winding points or eliminated the need for the creation of resin impregnation units.

It should be noted that conductor rails are only one type of structure or Represent components formed on the device according to the invention can.

Obviously, almost any type of structural part can be on the device by adjusting the size and cross-sectional shape of the mandrel and by the Creation of the desired winding points are formed.

Device for the production of reinforced pipe or line materials with roving points arranged at the top.

According to the invention, a modified form of a thread winding device can also be used A10 is created which is illustrated in Figure 24 and is similar to device A1 is. The device A10 differs from the device A1 in that headfirst or ceiling thread sources are used, eliminating the need switched off for a slip-on gate arranged on the floor and a resin container will.

The device A10 generally includes a base plate 220 the upright A-frame 221 with a support 222 for supporting a fixed one Mandrel 223 is attached in a boom position. The mandrel 223 is each of the The mandrels described above are similar and can be either round or non-round Have cross-section. At a perpendicular distance from the base plate 220 and to be viewed the components described below and those on the floor panel 220 are arranged, is a hanging support plate 224 with upright slip-on gates 225 arranged, each having a supply of roving bobbins 226.

Roving strands 227 are drawn off from each of the bobbins 226 and unwound and to the solid mandrel 223 to form longitudinal strands thereon applied in the ice described in detail below.

On the base plate 220 is spaced in the forward direction A-frame 221 also has a pair of upright guide posts 228 with guide openings 229 for receiving the roving strands 227 @ The strands are then by a carding plate 230 for applying the strands to the mandrel 227 in one Longitudinal pattern so that they essentially envelop the mandrel. The carding plate 230 can be mounted on any suitable support structure. It can be seen that the upright posts 228 and carding plate 230 are the first string application point form.

On the base plate 220 are spaced from that described above Longitudinal application point in the forward direction helical winding points W1, 72 attached, substantially any of the helical shapes described above development points are the same. These places usually carry bobbins of roving 231 and the strands coming from these reels 231 are passed through eyelets 232 and then around the longitudinal strands as they pass through the winding points @ 1, W2 wrapped around.

On the base plate 220 is at a distance from the winding point W2 an upright frame 233 in the forward direction to wear a Resin impregnation unit R1 attached, which is arranged to the mandrel and take up the strands wound around it (cf. Fig. 24). Bs can thus be seen that the location for the application of longitudinal strands and the winding locations TJ W1 and W2 form a i) reierkombination of winding points and that in this Three combination of spots applied strands immediately afterwards impregnated will. It can be seen that the resin impregnation unit R2 as well as the Haraimprängierungseinheit R1 can be used.

On the base plate 220 is in the forward direction at a distance from the Resin impregnation unit R1 a pair of upright guide posts 234 are arranged, which are equipped with openings 235 and furthermore a carding plate is 236 µm arranged around the circumference of the mandrel. Place the posts 234 and the carding plate 23Ç represents a second application point for the application of longitudinal strands. Roving strands are obtained from an overhead feeder 237 which is a hanging support plate 238 with upright Aufsteckgattern 239 and roving bobbins 240 includes. The roving strands 241 are unwound from each of the reels 240, through the openings 235 and through the carding plate 236 and to the severity previously wound on the mandrel 223 directed.
