Abstract

Laying fiber bands of filaments to form fiber arrangements includes individually spreading fiber bands guided by guide elements of weft layer or diagonal layer crosswise over two transport chains, depositing the fiber bands onto the transport chains, and forming a direction change fold having lower strand, upper strand, and apex into each fiber band. A start of lower strands and an end of upper strands are fixed in gaps between guide hooks. Laying fiber bands of filaments to form fiber arrangements includes individually spreading fiber bands (F) which are guided by guide elements (22) of weft layer or diagonal layer crosswise over two transport chains (1) equipped with guide hooks (13) and retainer needles (14); depositing the fiber bands onto the transport chains; and forming a direction change fold having lower strand, upper strand, and apex into each fiber band. A start of the lower strands and an end of the upper strands are fixed in gaps between the guide hooks. Formation of direction change fold includes executing racking for the fiber bands in a direction change phase of the weft layer or diagonal layer, and spreading out and hanging next to one another the apexes of the change direction folds into a row of retainer needles arranged close together and directed horizontally outwards. The retainer needles are wrapped through lowering and raising of the guide elements to fix the apexes of the change direction folds. Formation of upper strands of the direction change folds of a group includes inwardly moving a spreading edge (31) of a stitch spreader (3) which is aligned parallel to a movement direction of the transport chains from an outside position to directly above the retainer needles, so that the inward movement is crosswise to the movement direction of transport chains and fixes the apexes in the gaps between the retainer needles; and moving the guide elements of the weft or diagonal layers, so that the upper strands are formed between the retainer needles and the guide elements of weft or diagonal layers. During the execution of racking, a width of the fiber bands is reduced, and during the formation of upper strand, the reduced width of the fiber bands is enlarged. Cross-sections of the upper strands of direction change folds are guided parallel to a plane of retainer needles while keeping the sections of fiber bands between the spreader edge and the guide elements pinned. An independent claim is also included for an apparatus for laying fiber bands of filaments to form fiber arrangements, comprising a pair of endless movable transport chains equipped with a double row of vertically oriented needle-shaped guide hooks and with a row of retainer needles horizontally oriented and arranged so that the mountings of retainer needles are lower than foot sections of the guide hooks, guide elements for weft layer and/or diagonal layer aligned perpendicularly to a laying direction of the fiber bands between the transport chains, creel(s) with bobbins arranged to unwind tangentially to supply groups of fiber bands per weft layer and/or diagonal layer, and stitch spreader(s) structured and arranged to be guided and controlled outside the transport chains and being assigned to each transport chain for each weft layer and/or diagonal layer. The retainer needles are oriented outward for guiding and fixing direction change folds. The guide elements are structured and arranged to guide endless fiber bands. Each stitch spreader is structured and arranged to be guided in a displaceable manner within a customary movement area of guide elements of the weft layer and/or diagonal layer and crosswise to a movement direction of transport chains. Each stitch spreader has a spreader edge aligned parallel to the transport chains and movable from outside the assigned transport chain and over the retainer needles up to an area of mountings. Each stitch spreader is structured to extend over an area of the direction change folds of the fiber bands.

Description

The invention relates to a method and an apparatus for laying slivers made of filaments by means of iridescent weft or diagonals to fibrous areas between two with guide hooks and retention pins equipped transport in different directions and strained fed to such a pre-consolidation station, wherein the endless, flat Sliver individually spread, by means perpendicular to the specified direction of laying aligned guide elements of the weft or diagonal layer across guided over both transport chains and wherein each of the slivers, its guide element the series of guide hooks of the transport chain crosses arriving, is formed in each case a turning fold, the lower one Trum, an upper strand and a vertex and in retaining elements is mounted.

A method of the type mentioned was proposed by DE 101 49 161 C2. The band of slivers becomes diagonal across the transport chains with the help of a shot or Diagonallegers out. The guide elements for the slivers are aligned perpendicular to the direction of movement of the gun and shotgun arranged in a line next to each other parallel to the transport chains. The Transport chains have two spaced rows of hooks. Adjacent to the scrim are the guide hooks. They have closely spaced vertical needles with pointed top. Outside this row of guide hooks is another row with after up and out directed return needles. These are also in high density arranged.

The guide elements on the weft or Diagonalleger are vertically immovable. In the turning phase, a so-called behind the guide element of the shotgun. Crease tensioner introduced, the upper and lower strands of the turning fold on The vertex of the same leads separately from each other, until both dreams after completed Offset of the upper Trumes by means of the above-beveled offset rake the Row of guide hooks are handed back. During the execution of the The fibers of the turning fold are offset by a so-called sling tensioner tense and collected and the series of retaining hooks in the form of a strand to hand over.

This procedure requires because of the large number of involved in the process Tools a very high control effort. The desired effect, namely to arrive at a really gap-free design of the scrim, is achieved only with restrictions. The working speed remains limited and is unsatisfactory. When changing the width of the slivers or at the change in the orientation of the sliver between the transport chains The work elements must always be adapted constructively to the new conditions become. The effort is high.

DE 197 42 721 C1 discloses a method and a device for laying and setting up weft threads known, in which the transport chains also equipped with guide hooks and needle-shaped retaining hooks. The weft threader lowers in conjunction with a pusher rail outside the retaining hook under the tips of the same after having a first Has performed offset. After completing another final Offset below the tips of the retaining hooks raises the weft yarn guide again and places the weft crowd, now between the retaining hooks and the Schussfadenfüh rer is tense, at a predetermined location in the Row of guide hooks of transport chains.

However, with this procedure and this device, it is only possible Weft threads whose weft threads are not connected to one another laterally, Reliably hang in the transport chains. For slivers from z. Eg carbon or glass filaments in which the filaments are in a predetermined, defined situation - namely forming a band - by means of adhesive substances together be held, this procedure is not suitable. During the offset the cross sections of the sliver uncontrolled, so that a uniform hanging, especially the upper Trumes, in the series of Guide hook can not be guaranteed. In addition, during the offset a sliver within a guide element on the weft the band transformed into a strand. There is no way to preform this strand the handover to the leadership hook spread again. In the edge area of the Occasionally, irregular lanes would result, which are considered to be significant quality defects be considered. This procedure is therefore for the laying of Filament fiber slivers not suitable.

DE 100 21 341 A1 describes a similar device. The gunner Here are instead of the pusher rails additional Bandffixierungen, their execution and mode of operation remain unclear, assigned. Avoid these band fixations obviously during the offset behind the retaining hooks a pushing together the group of threads. It is not possible with this arrangement, slivers made of filaments. The pivoting of the guide elements bearing Last would lead again and again to strand formation. This can not be Produce gassenfreien slips of fiber ribbons.

From DE 102 07 317 C1, a further device has been known. The parallel weft yarn guides aligned with the row of guide hooks Diagonallegers has guide elements whose guide surfaces parallel to Row of guide hooks are aligned. The weft yarn leader does not lead Movement in offset direction off. The offset is due to a standard offset rake made in a known manner the outward and upward directed return pins is assigned.

By the movement of the offset rake - regardless of the weft - is a led strip during offset within the guide elements in the Gunner transformed into a rope. This strand is finally in the Row of guide hooks inlaid, forming the dreaded alleys.

By the unpublished DE 103 12 534 was in training the first DE 101 49 161 C2 proposed a modified device proposed in the u. a. the transfer of the rope-shaped vertex of the turning fold of the Fold the tensioner to the retention hooks should be improved by that instead of the series of retaining hooks a kind of clothing (distributed on a surface Return needles) is provided.

That too did not bring the desired success. The device and its control are similarly elaborate as shown in relation to DE 101 49 161 C2 has been. Loose fibers from the sliver of the turning fold become partly too led into the nest and so it comes there to unwanted faults.

In a further variant of this aforementioned non-prepublished document are nachlaufend activatable the gunner with its guiding elements Associated with the position of the slivers of the upper strand of the guide Fix the turn-fold laterally and vertically in a plane parallel to the tips of the Align guide hook. The function of the loop holder takes over here Folding clamp, which is pivotable about an axis. This hands over his turn fold each a single retaining hook per sliver. This way of working is also unsatisfactory, especially in the transfer of the turning fold From the folding clamp on the individual retaining hooks the turning fold uncontrolled to be led. The release of this fold by the folding clamp leads to Relaxing of fibers and slivers in the scrim.

In view of these seemingly unsolvable difficulties in hanging endless Filament slivers in the hooks of the transport chains have been tried previously cut fiber slivers in stretched form over the two transport chains to align and hook into the rows of guide hooks of the transport chains. The free ends of the sliver sections were spent - down directed - in another clamp on the transport chain, attached to each laying arrangement was opened again before new end sections are introduced. This way of working was also very difficult to control. Not directly with the clamping surfaces of the terminals coming into connection filaments The slivers could not be held securely and taut. The Interaction of the terminals with different function is under industrial Conditions at sufficiently high speed unmanageable.

The object of the present invention is to provide a method and an apparatus for laying endless filaments of filaments to be proposed with simple technical means the distortions of the sliver in the turn fold so control that both dreams under defined conditions in the Hooks of transport chains can be inserted and the location and the voltage the inserted fiber ribbons are maintained between the transport chains.

This object is achieved by the method according to claim 1 to surprising solved in a simple way.

The first significant advantage of this solution is that the sliver sections the Fadengeleges between the transport chains and the sliver sections in the area of the turn fold by the reliable fixation of the fibers the slivers in guide hooks with narrow streets in terms of their voltage behavior be separated from each other. A temporary loosening of individual Fibers in the area of the turn fold does not automatically lead to a loosening of the Fibers in the scrim.

The second major advantage of the new method is that, in particular the upper strand of the turn fold after the crests into the retaining hooks were inserted directly through the weft or Diagonalleger, by means of simple stretcher can be so taut and guided that a straightening up avoided this upper Trumes before hanging in the guide hook becomes. Possibly. excess fiber lengths are near the apex area of the Turned fold held. At the same time, they become one-sided during offsetting shifted band cross sections in the area of the guide elements by the effect the applicator again distributed over the entire management area, so that the upper run of the turn fold completely spread out and stretched the guide hook can be presented.

The number of tools required for this process is significantly reduced Service. There are neither individually controllable folding clamps nor guide combs or loop holder required. The scrims produced by this method are, as far as necessary, also targeted and reliable off-road produced.

With the modification of the method according to claim 2 is achieved that a single stretcher for several side by side supplied slivers with a continuous insertion edge can be used. The training and Control of the feeders is simplified considerably.

The design of the method according to claim 3 leads to a higher security in that the excess fiber sections in the area of the turn fold kept away from the area of the upper dream, the guide hook is presented for hanging.

The design of the guide hook according to claim 4 allows the reliable Separation between the tape sections in the scrim and the tape sections of the Turning fold. A high uniformity of the eggs is achieved in particular in that one - in the thread run in front of the guide elements - the individual Slivers independently clamps and guides and that the guide surfaces this tension and guide pins on the direction of the guide elements are coordinated.

The device defined in claim 6 for carrying out said method is simple and straightforward and brings in relation to known devices significant simplifications in terms of tools and necessary Precision of the control movements.

The design of the double row of guide hooks and the series of retaining hooks according to claim 7 ensures particularly good clamping properties at the same time trouble-free insertion and removal of the slivers.

The embodiment of the weft and Diagonalleger according to claim 8 is used in particular The modification of the method according to claim 5.

The design of the gate according to claim 9 reduces the probability that randomly twisting the bands in the threadline between the spool and the Shot or Diagonalleger arise. Such distortions would become arbitrary Irregularities in the clutch in the form of limited in length Lanes lead.

The use of conveyor or guide rollers or tension rollers in Inlet of the slivers according to claim 10 prevents the winding of individual filaments on these rollers and supports the spreading guiding the slivers.

The laying device, as used in particular for multiaxial Fadengelege is, consists of two laterally of the laying arrangement movable transport chains. 1 These transport chains 1 move i. d. R. uniform in the direction of a Processing site, which is usually the site of action of a stitchbonding machine. For every Thread layer of Geleges a separate laying arrangement is provided, the Shot or Diagonalleger 2 in different directions over the Movement path of the two transport chains 1 to move back and forth. On a Presentation of this overall arrangement is waived. It belongs to the general known prior art.

The arrangement of the guide 13 and retaining elements 14 on the transport chain 1 is apparent from FIG. 1. On a support plate 11, each with a Chain link is connected, there is a two-part version 12. Im vertical part of this version 12 are upwardly directed guide hook 13th arranged in the form of a double row. The guide hooks 13 are relatively narrow and have narrow lanes in the direction of the two rows of needles. It is advantageous to arrange about 15 to 25 needles per inch. Well proven has the arrangement of 20 needles per inch.

The shank cross section of the needles of the guide hooks is flattened vorteihafter way. The larger cross sections extend transversely to the direction of movement of the Transport chains 1.

In the horizontal portion of the socket 12, the return needles 14 are attached. The return needles 14 are similarly densely arranged and shaped as the needles the guide hooks 13. However, these retaining hooks 14 are preferably aligned horizontally. It would also be possible to use the same at an angle to Horizontal tilted up or down. The horizontal orientation However, it has become particularly with regard to the production of the versions proved to be useful.

In the area of a laying arrangement is a on the shot or Diagonalleger 2 arranged weft guide provided. The weft guide exists here from a guide rail 21, in which the guide elements 22 are arranged. At least these guide elements 22 are movable in three directions. Namely once across or diagonally to the transport chains for the laying motion, then in the longitudinal direction of the transport chains for the execution of an offset and finally in the vertical direction for the defined hooking in the guide hook 13 and in the return needles 14.

Between the level of the return needles 14 and a partially raised again Guide element 22 is a filler 3 horizontally from the outside to arranged inside movable. This inserter 3 is shown in FIGS. 1 and 2 its Einreichkante 31 drawn approximately in its foremost position.

The example of FIG. 2, the operation of the device in the individual Phases described with reference to a guide element 22 / A to 22 / E. From Coming down on the left, the guide element 22 first crosses the row of the Guide hooks 13 of the transport chain 1. Behind this row of guide hooks 13, the guide elements 22 lower, so that the sliver F in the Row of guide hooks 13 is fixed by clamping. If this process is completed, begins during the delay of the shotgun 2 already the Offset V1 in the longitudinal direction of the transport chain 1. The guide elements 22 / A are still above the level of the retention needles 1. Is part of the Total offset - offset V1 - covered, the guide bar 21 of Schusslegers 2 lowered with their guide elements 22 down.

The pusher edge 211 and 212 of the guide bar 21 moves the sliver F downward. It is spliced by the tips of the return needles 14 and in the lanes between the return needles 14 fixed (position 22 / B). After Execution of another offset V2 in this lowest position is the Guide bar 21 with its guide elements 22 / C raised again. The Sliver is spliced again and into the lanes between the return needles 14 spent. The movement of the shotgun 2 in the direction of the other Transport chain 1 starts in this phase, so that the sections of the crest of the Turning fold FW finally fixed between the lanes of the return needles 14 become.

Once a sufficient vertical space between the return needles 14 and the guide elements 22 is present, the inserter 3 with his Forming edge ahead, preferably by means of a control piston, not shown moved in the direction of the guide pin row 13. In this movement of Envelope 3 also supports the insertion of the vertex section FWS the turning fold in the streets of the retaining hooks 14. At the same time holds the Einreichkante 31 the fibers of the upper strand FWO on the socket 12 of the retention needles 14. This creates a pull on the outer fibers of the sliver FWO exercised, with the help of which during the displacement in the guide elements 22 unilaterally displaced sliver F is compensated again.

This can be clearly seen in the position of the guide element 22 / D. simultaneously secures the Einstreichkante 31 in this position, that the parts of the sliver stay tensioned between the guide member 22 and this clamping edge and Free fiber parts accumulate outside the nip line. The upper strand FWO the turning fold FW is thereby spread and evenly stretched over the Row of guide hooks 13 in the direction of the other transport chain 1 moves. This tensioned section FWO of the sliver F is aligned exactly horizontally and is thereby presented to the guide hook 13 in a uniform height. A special lifting movement of the guide elements 22 is for insertion into the Row of guide hooks 13 initially not provided. The need becomes depending on the nature of the fiber slivers F presented from case to case the expert determined.

In Fig. 3, the position of the working elements is shown again. This illustrated Position corresponds approximately to the position 22 / B of the guide element in FIG. 2. The first part of the offset V1 is completed and the guide elements 22 / B of Shot or Diagonallegers 2 lower with the pusher edge 211 below the Row of retention pins 14. The liner 3 is still in the resting position.

The position 22 / C of FIG. 2 is shown in FIG. 4. The guide rail 21 of the Shot or Diagonallegers 2 is already with its guide element 22 / C again has been raised and is in the first phase of its movement to Row of guide hooks 13. The inserter 3 has almost reached its end position. He clamps sections of the upper run of the turning fold FW to the socket 12 of the return needles 14 and directs the sliver of the upper run FWO horizontally.

Fig. 5 shows a following position. The guide bar 21 of the shot or Diagonallegers 2 has moved up the series after further lifting Guide hook 13 of the transport chain 1 moves and tensions that of the inserter 3 flat upper run of the folding fold FW so that the parts of the Split sliver F through the tips of the guide hooks 13 and join the individual fiber strands in the streets between the guide hook 13 to the Move the reason of the same. There these bands are clamped. Possibly. loose Sections in the area of the folding fold FW do not shift into the area of the Fadengeleges between the transport chains. 1

Of particular importance is that the sliver F between the stretcher 3 and the guide member 22 on the gun 2 is always curious. These regularly existing voltage is determined by a known clamping arrangement from guide pins 14 and dowel pins 13 above the guide elements supported on the weft 2. In contrast to the known prior art However, this guide and clamping arrangement here for each sliver F individually intended. Such a guide and clamping arrangement is shown in Fig. 6. The guide pins 24 and the clamping pin 23 are parallel to the guide surface in the Guiding elements 22 aligned. The clamping pin 23 is in the horizontal direction elastically biased so that it temporarily to form a small wrinkle temporarily store excess sliver sections in the area of the turning fold FW can.

This parallel orientation of the guide elements also applies to the feed roller. 4 to, which is at a distance above the range of motion of the shot or Diagonallegers 2 between the two transport chains 1 is located. This regularly only difficult to access feed roller 4 is called a so-called polygonal roller or as Roller with longitudinal ribs, which are aligned along generatrices, designed. This design should ensure that not individual from the Association of the sliver F winding fibers wrap around this feed roller 4.

The scheme of feeding a sliver from the bobbin to the feed roller 4 is shown in FIG. The guided on a horizontal axis in a gate Coil 8 is braked slightly by means of brake 9. From the expiration point of the volume It will be the same over a greater distance, up to several meters can, led to a broad, frangeless first guide roller 7, on which the Sliver F as a function of the respective expiry point on the coil. 8 can shift laterally (see Fig. 8). The upper strand of this forming here Sling of the band will then also over a long distance to a second guide roller or led to a delivery 6. A strong side Distraction of the sliver F is thus reliably prevented.

The delivery mechanism 6 has three driven feed rollers, which the fiber ribbons F with constant speed of the coils 8 deducted. The to a delivery mechanism 6 belonging coils 8 are in the gate along their axes against each other offset so that their slivers without lateral guidance in Place it at a suitable distance on the side of the delivery rollers.

The different take-off speeds required by the laying process and the resulting temporary sliver excesses are in Area of the tape memory 5 cached. To secure the spread Location of the sliver also on the provided with lateral collars tensioner 51 has the same a polygonal tread for the sliver F. This is here formed by individual annularly arranged pins (see Fig .. 9).

This arrangement and design of the guide elements in the gate has proved its worth. The number of spins in the band that can happen by chance has thus significantly reduced.
