Description

The invention relates to a device for transferring a threading strip or a material web within a manufacturing machine and / or processing of the material web, by one Takeover area along in a transfer area a web path and a method for transferring a threading strip or a material web according to the preamble of claim 42.

Devices and methods of those addressed here Art are known (DE 40 37 661 C1). These will within a machine for manufacturing and / or Processing a material web used and serve the transfer of the material web respectively one of these strips, the is also referred to as a threading strip by one Takeover area in a transfer area. At Commissioning of the machine or after a web break becomes the threading strip or the material web with their entire width along one Management and / or treatment facilities specified Guided path. This process will also known as threading. The known device includes a rope guide with two ropes, at the beginning of the rope guide in a so-called Cable shear converge to each other. In one Takeover area arranged rope shear is the Threading strips / the material web and between the ropes clamped. The threading strip / the Material web is shared with the Ropes along the path to a transfer area in which the threading strip / Material web to a subsequent establishment of the Machine is handed over. The overpass is at reduced or full machine speed performed up to 2,000 m / min and above can be, the ones used for the transfer Ropes are often faster than have the machine speed. It has found to be disadvantageous that the threading strip / Material web in many cases not can be held securely by the ropes and during the flyover is lost, so that the Transfer process can often be repeated several times until a successful transfer of the threading strip / Material web from takeover to the transfer area is complete. After this There are always more convictions Web breaks because the threading strip / the material web, while this / this lengthways is tensioned, commutes and runs back on the ropes can where it is destroyed. Through the multiple Startups until a successful transfer completed is downtime of the machine increased and thus reduced their productivity.

It is therefore an object of the invention to provide a device and to create a process in which a secure transfer of a threading strip or a material web even at high machine speeds can be guaranteed.

To solve this problem, a device proposed that mentioned in claim 1 Features. Because at least one Pick-up device that is used to transfer the threading strip / Material web from the takeover area to the transfer area essentially along the Web path can be shifted at a speed which is smaller, in particular significantly smaller, than the running speed at which the threading strip / Material web during the transfer process through the machine a high level of functional reliability can be guaranteed. In connection with the present invention the term "railway path" means the distance through the manufacturing and / or machining process the web of material respectively through management and / or treatment facilities is specified. The threading strip / the material web is for example over rollers, through roller presses, over device areas, over / through treatment facilities, over / through measuring devices and / or guided on tapes, their arrangement within the Machine determine the path of travel or establish. The recording device is equipped with a lower speed along the path of the web shifted than the threading strip / the material web, his / her speed the machine speed during the transfer process corresponds. The threading strip / the material web is with the help of the receiving device at the point where the receiving device is inside the machine at that moment, out of the web path, for example laterally. This causes the material web to run up on the receiving device, its speed of displacement less, preferably considerably is less than the running speed of the Threading strip / the material web, excluded. Threading the strip / web is therefore also possible at very high machine speeds, because the transfer speed, that is, the Speed of displacement of the receiving device regardless of the running speed of the material web is variable.

It becomes an embodiment of the transfer device preferred, in which the receiving device in the direction of the path and opposite is relocatable. This can be an open Guidance of the receiving device can be realized, that is, the receiving device does not have to Circle to be led from the transfer area to the Takeover area to be relocated, but can against the web path in the takeover position to be led back. The speed of displacement is preferred and direction of the receiving device variable between two transfer operations.

In a particularly advantageous embodiment it is envisaged that the rate of displacement variable during a transfer process, is preferably adjustable. The threading strip / the Material web can thus - in the direction seen the web path - in sections with different Speed. Thereby is a relatively fast and particularly safe Transfer possible, for example in the area a treatment or management facility, over / through which the threading strip / the material web is led or threaded, the anyway relatively low displacement speed can be further reduced.

An embodiment of the is also preferred Transfer device, which is characterized by that the receiving device in the area or relocated outside the web path respectively to be led. The transport route of the reception facility can, for example, the arrangement of the threading strip separated from the material web be adapted to either one Edge of the material web or in one between the Separated material web section lying web edges becomes. Furthermore, the receiving device is guided for example in the middle of the path possible. If the material web with your entire width from the transfer area to the transfer area transferred, the receiving device can also here in the area or outside the web path be relocated. With a tour of the Receiving device is outside the path of the web these designed such that their scope in the path of the train, at least until Area in which the threading strip / Material web is to be guided.

A guide is assigned to the receiving device, which has at least one guide element. In an advantageous embodiment provided that the at least one guide element formed as a rope, ribbon, chain or the like is. Such guide elements can be stationary, that is, immovable so that the Recording device along the through the guide elements predetermined guide path, for example on the guide elements, is movable while the guide elements are at a standstill. In another embodiment, the or is the guide element by means of a Drive driven, so that on the guide element attached receiving device along the through the guiding element (s) given the guiding path can be moved. It is also conceivable that the receiving device compared to the relocatable Guide element perform a relative movement can.

According to a further embodiment variant, this is at least one guide element from a role, preferably profiled roll. The reception facility can be done with the help of along the Web run arranged rollers, of which preferably at least part by means of a drive is drivable, relocated.

An embodiment of the is also preferred Transfer device, which is characterized by that the leadership path of the leadership is longer than the train path. The route of guidance therefore extends not just from the takeover area to the transfer area or vice versa, but also in addition, so that the receiving device from the area of the web path can. This makes it possible to use the receiving device while the machine is running for the production and / or processing of the material web to shift to a position that is not immediate to the railway track along which the Material web guided during the production process is bordered. This can ensure be that the receiving device the manufacturing and / or machining process is not affected or bothers.

In an advantageous embodiment of the Transfer device is the guide element too connected to an endless loop, that is, that Guide element extends from the takeover area essentially along the path to the transfer area and from this back to the takeover area. In connection with the present invention is called "extend" both a Leadership as well as an arrangement of the guide element Roger that. So the guide element is relocatable or stationary within the machine arranged. This makes it possible, for example, that the receiving device after a transfer operation relocated in the same direction is carried out, for example to the takeover area. The reception facility can always shift in the same direction become.

An exemplary embodiment is also preferred the transfer device, which is characterized by that the receiving device at least an at least one receiving opening Includes recording head. When taking over the threading strip / Material web is this in guided the opening with suitable means. The receiving head is preferably a further treatment device subordinate.

The device described below is general for transferring a threading strip or a material web within a machine Production and / or processing of the material web applicable. The material web, for example paper, Cardboard, textile web, plastic film, fleece, non-woven, is manufactured in the machine and / or processed. The following is purely exemplary assumed that this is a paper machine acts in which a paper web is produced and / or processed. Under "processing" is in connection with a paper web for example finishing, coating, printing, Brush or the like understood.

Figures 1 to 4 each show a schematic Schematic diagram of an embodiment of a device 1 arranged inside a paper machine is and for transferring one below paper web generally referred to as material web 3 from a takeover area 5 into a transfer area 7 serves along a web path. in the Relation to the present invention under "Bahnlaufweg" by guiding and / or Treatment facilities, such as rollers or device areas, predetermined running distance of the material web 3 understood. Figures 1 to 4 show a sequence of functional steps of the transfer device 1. In the between the takeover area 5 and the transfer area 7 lying part a processing station 9 is arranged on the machine, the one in this embodiment Coating machine is. The processing station 9 is - seen in the running direction (arrow 11) of the material web 3 - a two-tier dryer group 13 upstream and a single-tier dryer group 15 downstream. The one from the last one. Drying cylinder 17 of the Drying group 13, which is arranged in the takeover area 5 is, material web 3 is running over Web guide rollers 19 deflected and by a pressing device 21 passed through, the several, here in total has two press rolls. After going through the pressing device 21 becomes the material web 3 a finishing unit via further web guide rollers 23 supplied in which a coating medium on the Material web is applied. Then will the material web 3 on an infrared dryer 25 passed by and through a two-part air dryer 27 passed through. After the air dryer The material web 3 becomes 27 via web guide rollers 29 and 31 deflected and onto the first drying cylinder 33 of drying group 15 listed. From the drying cylinder 33 the material web 3 enters the subsequent part of the machine. The material web 3 is within the processing station 9 or between their web guide rolls, Drying and coating equipment in one led free train, that is, the material web 3rd is not supported by a conveyor belt.

When starting up the machine or after a Web break is the material web 3 or one of these separated, also known as threading strip Streak through the entire machine or part of the machine along the path of the web passed through. This process is also called threading designated. For this is in the area of the processing station 9 the transfer device 1 provided, which are described in more detail below becomes.

The transfer device 1 here only comprises one a guide having 35 guide 37, for guiding a receiving device along serves the path of the web. The guide element 35 is of one in this embodiment Rope 39 formed, forming an endless loop connected is. Alternatively, the guide element 35 also of at least one chain or at least to form a band. Another preferred Embodiment are at least two Guide elements provided, for example two Ropes or a rope and a chain running parallel or at least essentially parallel in one Distance from each other. The ropes are made for example made of metal or one high-strength and heat-resistant plastic, for example kevlar. The closed rope loop is in some areas over pulleys 41 and along the path of the web, for example over loose rope sheaves, that sit on the guide roller journals the same web guide rolls through the dryer 25, 27, the finishing unit 23 and the pressing device 21 led, over or by the the material web 3 is also guided. The rope 39 is optionally in the direction of a drive 43 of the path and in the opposite direction with different, preferably adjustable Movable speeds. The drive 43 includes here a role over which the rope 39 is guided is, the roller can be loaded with a torque is. With the help of the drive 43 can at least one rope 39 from standstill in both directions with the desired acceleration to a given speed, for example 5 m / sec.

Below the transfer area 7 is a storage station 45 provided for a hose 47, the its free end with a receiving device 46 and on his other - not in Figures 1 to 4 shown - end with a further processing device is connected, for example one Collection container for the material web or one Disposal and / or recycling plant. The reception facility 46 has one with the hose 47 connected receiving opening. The hose 47 can for example be rectangular or round Have cross section and made of a flexible material consist. In another embodiment the hose is made of a flexible, for example spiral tube made of polyurethane (PU) educated. The hose 47 can be detachable with connected to the at least one rope 39; to the Example he can with suitable - not shown - Funds are attached to it.

On the function of the hose 47 connected Receiving device 46 is described below the explanation of a transfer operation closer received. When starting up the machine or after a web break, the material web 3, after them from the last drying cylinder 17 of the Drying group 13 has expired, down from the Machine led out and in this embodiment in a collecting container 49, a so-called Pulper, caught. Not with the help of one shown cutting device is a threading strip from the material web 3, for example in whose border area, separated, the first together with the remaining web runs into the collecting container 49. In another embodiment provided that the threading strip from the material web 3 in one direction of rotation (arrow 11) Material web 3 seen - upstream of the takeover area 5 Part of the machine separated and the Remaining web is diverted so that only the threading strip via the drying cylinder 17 into the collecting container 49 is performed. The rope 39 is by means of of the drive 43 in the direction of an arrow 51 shifted. The one attached to the rope 39 Hose 47 tracked from the storage station 45. The receiving device connected to the hose 47 46 is now shown in Figure 1 Rest position along the path in the takeover area 5 moved to a takeover position (Figure 2). The takeover position of the receiving device 46 is located here below the drying cylinder 17, from which the material web runs and is guided into the collecting container 49. At a another embodiment can be the takeover position also lie above the drying cylinder 17. Then, that is after the receiving device 46 has reached the takeover position, becomes at least the part of the material web to be transferred 3, i.e. the threading strip, with the help a cutting device, not shown, across to the web running direction over the entire width of the strip running off in the pulper and the new beginning of threading in the Receiving opening of the receiving device 46 directed, for example by means of an air flow, a Suction tape (Fibron tape), a Coanda sheet or other control equipment. From there the threading strip through the entire hose 47 to one Treatment facility led.

The threading strip can be taken over, for example then take place when the receiving device 46 is at a standstill or during this is shifted from the rope 39. After the takeover of the threading strip, the rope 39 is in the direction an arrow 53 shifted, ie in the direction of Web path. The Hose 47 and the receiving device 46, whereby the threading strip is transferred. The speed of displacement the receiving device 46 from the transfer area 5 to the transfer area 7 is variable and is chosen such that the Threading strips safely along the path of the web to be led. The fact that the threading strip from Takeover area to the receiving device 46 and from this through the hose 47 from the web path is brought out, a transfer speed the receiving device 46 can be realized, the smaller, preferably significantly smaller, is than the speed given by the machine of the threading strip. The part of the threading strip running at machine speed, that away from the receiving device 46 is redirected, is not in transferred the transfer area 7. So it's possible that the material web with, for example 2,000 m / min through the material web production and / or processing machine is guided while the transfer speed of the threading strip for example, is only 300 m / min. Since the Recording device 46 receives the threading strip and the led out of the web path Part of the threading strip through hose 47 is a slow transfer of the threading strip from the takeover area to the transfer area possible without that during the transfer process the machine speed must be reduced. By removing the via the receiving device part of the threading strip guided into the tube 47, which just didn't lead to the takeover area , the threading strip will run up on the receiving device 46 due to the Speed difference between running speed the material web and transfer speed the receiving device avoided. Hereby can despite slow transfer speed with high machine speed at the same time Longitudinal stretch of the strip at a desired value being held.

In the position of the receiving device shown in FIG. 3 46 is the threading strip already up to that of the pressing device 21 Web guide roller transferred. It becomes clear that the receiving device 46 is guided such that the threading strip both over the web guide rollers as well as through a gap between two rollers or can be threaded through. In the illustration according to Figure 4 is the receiving device 46 already in their transfer position procedure in which the threading strip on the first Transfer drying cylinder 33 to drying group 15 becomes. The handover of the threading strip to the drying cylinder 33 takes place in this embodiment in that the threading strip in the one between the drying cylinder 33 and one above guided conveyor belt 55 formed nip becomes. The part of the threading strip that is already detected by the recording device and by the hose has been led out of the machine, tears off and already at machine speed threaded part of the threading strip, the has not yet been detected by the recording device, is together with the conveyor belt 55 on the Drying cylinder 33 in the subsequent part of the Led paper machine. So the transfer process is completed so that the receiving device 46 in the parking position shown in Figure 1 can be relocated in such a way Distance to the web path is arranged that a Disruption of the production process and preferably contamination of the receiving device 46 is avoided become. Finally, the is threaded Strip gradually widened until the web of material with their entire width through the machine is led.

It is clear that the threading strip is only then completely transferred or into the Processing station 9 is threaded when the Recording device 46 that shown in Figure 4 Has reached position. The one from the reception facility 46 during a transfer operation from the Machine, but at least led out of the web path So it becomes part of the threading strip not transferred, so that the designation for this part "Threading strips" in the true sense is no longer applicable. The transfer device 1 is particularly characterized by a high Functional reliability even at high machine speeds during the transfer.

By the described with reference to Figures 1 to 4 Transfer device 1 can the threading strip at a speed of 5 in the transfer area 7 are transferred, which is essential is less than the machine speed, so the running speed of the and / or processing machine guided material web. Through the safe guidance of the threading strip by means of the receiving device 46 a tear-off of the threading strip during the transfer process be practically excluded so that by transferring the threading strip downtime caused by the machine known machines in which the threading strip by means of an initially described Rope guide is transferred can be reduced. Another advantage of the transfer device 1 compared to the known rope guide is that the risk of an accident in the area of the machine stopping people. With the known Rope guidance exists especially at high Displacement / machine speeds the risk that the ropes from the guide devices jump or due to material fatigue or tear off damage.

From what has been said above, it is immediately clear that the transfer device 1 also for transfer a full web of material, for example Toilet paper, with its entire width can be used and their use is not only limited to the transfer of a threading strip is.

To take over from the receiving device 46 transferred threading strip and its continuation to a - in the direction of travel (arrow 11) of the material web 3 seen - downstream part of the machine is in an advantageous embodiment a takeover device, not shown in the figures provided, for example a rope guide, at least one suction belt (fibron belt), a further receiving device 46, a Roll press and / or includes a reel-up. Furthermore, in the takeover area 5 in the Transport means not shown are provided be the one of the takeover area 5 upstream part of the machine arriving Threading strips / material web to the receiving device 46 passes. The structure and the function the means of transport and the takeover facility can be identical and for example each of a suction belt are formed.

Figure 5 shows part of an embodiment the transfer device 1 according to FIGS. 1 to 4, namely one connected to a hose 47 Pick-up device 46, which has a web guide roller 57 is performed. The receiving device 46 are several, here a total of two parallel and in a spaced guide elements 35 assigned, formed by ropes 39 and 39 ' and for guiding and transporting the receiving device 46 and the hose 47 serve. The Receiving device 46 comprises in this embodiment a pickup head 59 which has a pickup opening 61, into which one of a material web separate threading strips in the edge area 62 is performed. The recording head 59 can be formed in one piece with the hose 47 or be connected to it. The hose 47 has a circular cross section and is firmly connected to the guide elements 35. This are in the area of the web guide roller 57, preferably on the driver's side, on an edge section 63 the web guide roller 57, which is outside the Pathway is. The train path is located to the left of an imaginary, dashed line first level E1 and borders directly on this on. The recording head 59 of the recording device 46 has an S-shaped course and protrudes into the Path into which the threading strip 62 is led. The hose 47 is with at least one connected vacuum source, not shown, by means of which the receiving opening 61 of the receiving head 59 can be subjected to a negative pressure can. When the hose 47 is suctioned, ambient air becomes sucked into the receiving opening 61. The flow generated thereby can thread the Threading strip at least in the receiving opening 61 supported. The flow also serves for tightening the threading strip, i.e. for adjustment the longitudinal train, as well as to support transporting the threading strip through the Hose 47.

The threading strip runs in the illustration according to FIG 62 into the receiving opening 61 of the receiving head 59, that means it is sucked in, and a further treatment device, for example, via the hose 47 fed. By a Relocation of the guide elements 35 in the direction of Double arrow 53 becomes that of the recording head 59 guided threading strips 62 along the path of the web, in this embodiment parallel to Web path, led. Because the threading strip 62 via the recording head 59 and the Hose 47 led out of the web path, here is sucked off, it is possible that the receiving device 46 during the transfer process from the transfer area to the transfer area at a speed is preferably relocated is significantly lower than the running speed the material web itself. This makes it a safe Guiding the threading strip 62 even at high machine speeds possible. That through the vacuum source generated gas flow within the As described, hose 47 serves for the threading strip 62 to tighten in the longitudinal direction. The at the receiving opening 61 of the receiving head 59 acting vacuum is preferably adjustable, to control the tightening of the threading strip. This can also be used to support the Takeover of the threading strip 62, as above described - in the takeover area 5 in the receiving opening 61 is used.

In another embodiment, there is a recording head provided that includes a vacuum source, for example a blower. The vacuum source is preferably integrated in the recording head, so that a compact design of the transfer device, especially the recording device possible is. By arranging the vacuum source it is in the recording head or in its area too possible on the hose 47 to discharge the part of the threading strip guided by the machine to renounce. Such a suction head leads Threading strips 62, for example laterally from the Machine out, where, for example, on the floor the machine is thrown. With an advantageous Design variant of the receiving device is designed as a shredding device Fan provided, for example as a fan designed with specially designed wings is. As a result, the threading strip can immediately after insertion into the receiving opening 61 of the Recording head 59 separated into small parts, torn and / or dismembered. The material web pieces are then through the hose 47 led out of the machine. But it is also possible that the recording head 59 is not with a hose is connected so that the material web pieces after shredding only from the side of the machine be blown out.

In a further embodiment, the Recording head 59 assigned a collecting container, the for example by means of the guide elements 35 together with the pick-up head along the path of the web to be led. This can, depending on the design of the blower, the threading strip in one Pieces or caught in many small pieces become. Furthermore, it is possible to have a combustion device to integrate in the recording head 59 or this -in the direction of transport of the Threading strip seen - to be arranged so that the in the embodiment shown in Figure 5 led out of the side of the web path Threading strips can be burned immediately. The ash can come out of the side of the machine, for example immediately applied or collected become. But it is also possible to go through the ashes one connected to the receiving device 46 Channel, hose or the like from the machine to apply. An embodiment is preferred, a well-known one in the recording head Shredder is arranged for shredding of the threading strip.

Instead of or in addition to that based on FIG. 5 Suction of the receiving opening 61 described the pick-up head engages the threading strip Have transport device, whereby the Guidance of the threading strip can be improved can. With the help of the transport device, for example as a pull press, vacuum belt, Coanda scoop, vacuumed drum or as a swirl device is formed, the threading strip can be detected and pulled into the recording head. This is advantageously a tension of the threading strip in the longitudinal direction during the transfer process defined possible.

Figure 6 shows schematically another embodiment the transfer device 1. parts that correspond to those in FIGS. 1 to 4, are provided with the same reference numerals, so that in so far to the description of Figures 1 to 4 is referred. The following is only intended to the differences are discussed in more detail. The Transfer device 1 here comprises a guide element 35, for example a rope, a tape or a chain, the ends of which are not connected are. One end of the guide member 35 is in a winding station 65, which is below the takeover area 5, for example in the basement of the machine, is arranged on a drivable roller 66 partially wound up. The guide element 35 will from takeover area 5 along the path of the web, for example over loose rope sheaves that are on the Guide roller journals sit up to the transfer area 7 and further to the storage station 45, in the the other free end of the guide element 35 also wound on a drivable roller 66 ' becomes. In the between the takeover area 5 and the transfer area 7 part of the machine can the material web 3 processed, for example be refined. It is therefore one described in FIG. 1 Processing station 9 can be arranged.

On the guide element 35 is a receiving device 46 held or attached, the by rotating the one with a symbol indicated drive 68 drivable rollers 66, 66 'clockwise from that shown in Figure 6 Rest or park position below the Transfer area 7 along the web path over the loose pulleys of the web guide rollers 67 to Takeover area 5 can be performed. The peripheral speed the rollers 66, 66 'can be varied. After the receiving device 46 the material web 3 or a separate threading strip in takeover area 5, is counteracted by rotation of the rollers 66, 66 ' Clockwise the guide element 35 together with the Receiving device 46 along the path of the web in Directed the transfer area 7 and to the first drying cylinder, indicated by dashed lines 33 to a subsequent dryer group 15. Particularly advantageous for the one shown in FIG. 6 Transfer device 1 is that this a relatively simple and space-saving structure having. The receiving device 46 can with a duct to which a vacuum can be applied, Hose or the like can be connected by through the threading strip or the material web is dissipated. The hose is on that Guide element 35 attached and preferably has a length that is greater than the web path. It is also possible that the of the receiving device 46 guided threading strips from the Machine, for example, led out laterally and further processed, for example crushed, burned, dissolved or in containers, baskets, Sieves, nets or the like collected and collected becomes. It is particularly advantageous that the Guide element 35 not closed Loop is connected so that an exchange of the Guide element 35 can be easily performed can.

In the embodiment shown in Figure 6 it is of course possible that the Pick-up device on two guide elements, preferably Ropes, attached, for example also a hose for removing the threading strip can be attached. The two ropes can together in a preferred embodiment are wound onto the rollers 66, 66 '. The rollers 66, 66 'can also in this embodiment from a standstill to a desired one Speed will be accelerated, the Direction of rotation is variable. To the tension of one flexible guide element, here adjust a rope to be able to, is at least one clamping device (Figure 18) provided with the help of Length of the guide element is changeable. For example the rollers 66, 66 'against each other twisted.

Figure 7 shows schematically a side view of a Embodiment of a storage station 45, the for example in the transfer device 1 according to Figures 1 to 4 can be used. The Storage station 45 is stationary within the machine for the production / processing of a material web arranged, for example in the basement of the machine, and includes a drivable drum 70, a hose 47 can be wound up. Around the hose 47 in the desired manner on the drum 70 are to be wound around the circumference of the drum 70 rollers 72 arranged next to one another provided that have the length of the drum 70 and there at the area of the drum in the tube 47 rest where the hose 47 is on the drum has wound up. The one to be wound on the drum or unwound part of the hose 47 is between two stationary profile rollers 74 and 74 'passed. On the function the profile rollers 74, 74 'is based on the figures 8 to 10 discussed in more detail.

In order to wind the hose 47 on the drum 70, it is turned clockwise. When unwinding the hose 47 from the drum 70 becomes this turned counterclockwise so that the Hose 47 through the gap between the profile rollers 74, 74 'is performed. In Figure 7 is with dashed lines Line a drive roller 76 indicated, which is pressed against the circumference of the drum 70 and by means of which a torque on the drum 70 can be applied.

Figure 8 shows schematically a top view of the Storage station 45 according to FIG. 7. It can be seen that the drum 70 has a profile 78 on the outer circumference has that adapted to the contour of the tube 47 is. Through the profile 78 and a shift the drum 70 in the direction of its longitudinal axis ensure that when winding the Hose 47 this in the desired manner on the Drum is wound, namely without overlapping or the hose loops lie on top of each other. It is clear that the position at which the Hose 47 in the gap between the profile rollers 74, 74 'is performed during the entire winding process remains unchanged. The outer circumference of the Drive roller 76 is on the outer profile of the drum 70 adapted and intervenes in this. With that effect the roller 76 also simultaneously the axial displacement the drum 70. The one passed through the hose 47 The threading strip reaches the on the Drum 70 wound hose 47 and through its free end in the direction of an arrow 81 a further processing device, for example a recycling plant or in a collection container, in which the threading strip is collected. The rollers 72 are not shown in FIG. 8.

Figure 9 shows part of an embodiment a guide 37 for a hose 47, namely one Deflection area 82, in which the hose 47 is clean is deflected by 180 ° as an example. The leadership 37 includes several different in this embodiment Leadership elements respectively devices, namely guide devices 84 as well as several schematically represented profile rolls 74 and 74 '. As can be seen from Figure 9, the Profile rollers 74 and 74 'spaced apart in such a way arranged that by the between the guide rollers formed gap led hose 47 um Is deflected 90 °. The hose 47 not kinked, causing a damming through the hose 47 guided threading strip securely can be avoided. It is possible that at least one of the profile rollers 74 and 74 'by means of a Drive can be driven and on the hose 47th is present or is pressed against it. This allows the hose 47 in the direction of the double arrow 88 to be relocated. On the profile rolls 74, 74 'will be described below with reference to FIG. 10 discussed in more detail. Furthermore, the management facilities 84 explained in more detail with reference to FIG. 11.

Figure 10 shows a cross section of the guide device according to Figures 7 to 9. It can be seen that the profile rollers 74, 74 'on a bracket 90th are rotatably attached. In the space between the profile rollers 74, 74 'becomes the hose 47 passed through. Through the essentially to the Outer contour of the tube 47 adapted profile rollers it is managed in a defined manner. A relocation of the hose 47 is only perpendicular to Image plane of Figure 10 possible. It is possible that at least one of the profile rollers is drivable is.

Figure 11 shows a cross section of one of the in Figure 9 shown guide devices 84. This includes a guide member 92 which is from a through hole 94 is penetrated. The essentially circular through opening 94 is arranged such that the top 96 of the guide member 92nd partially broken and a groove is formed. The width of the groove is less than the diameter of hose 47. This allows hose 47 to be secure are held in the through opening 94 and the threading strip can go to the Hose exit.

From the comments on Figures 9 to 11 clearly that the hose 47 by means of the guide devices 84, the guide rollers 86, 86 'and the profile rollers 74, 74 'are safely guided can. In an advantageous embodiment the transfer device 1 is provided that the guide assigned to a receiving device 46 37 exclusively from management facilities 84 and / or guide rollers 86, 86 ', which are essentially along the path and above are arranged. This can be done on additional Guide elements 35, for example ropes, pipes, Racks, chains or the like are dispensed with become.

The arrangement according to FIGS. 7 to 11 allows one Receiving opening 61 at the end of a hose 47 from Transfer area 7 to takeover area 5 and at The threading process can be moved back using the drive of the elements 70/76/74 or possibly 86, without Use of guide elements 35.

Figure 12 shows a plan view of a second embodiment a recording head 59a, the Base body out at a distance from each other arranged links A to K is composed. The Links A to K are divided into two in each Edge areas 98 and 100 of the receiving head 59a arranged Joints 102 articulated. By the distance between the links A to K have, is between each two links Air gap S formed. Because of the shown in Figure 12 The arrangement of the joints 102 is according to the Recording head 59a constructed according to the roller shutter principle transverse to the running direction (arrow 11) of the threading strip stiff and movable in the direction of travel.

On the path facing away from the threading strip Side of the receiving head 59a, that is in the edge area 100, is on each of the links A to K respectively an eyelet 104 is provided through which an outer Rope 39 'is threaded. An inner rope 39, which is a closer distance to the machine center has as the outer rope 39 ', is in the area of the recording head 59a interrupted. The one free The end of the rope 39 is attached to the link B by means of a Rope attachment 106 and the other end by means of a rope fastening attached to link H. 106 'preferably held in a clamped manner. The rope fasteners 106, 106 'are arranged such that the axes of the ropes 39, 39 'also in the area of Head parallel to each other. The two rope fastenings and the mounting head take up the tensile force of the rope 39, so form an intermediate piece of the rope. The one at a distance Ropes 39, 39 'running towards each other are outside of the web path, for example as in Figure 5 shown.

The links A to I, in the direction of travel of the web (Arrow 11) seen - have a larger width than the links J and K, preferably protrude into into the path of the train, i.e. into the running level of the Threading strip. The recording head 59a has in Edge area 98 has a receiving opening 61 to which an inclined towards the edge area 100 running air duct 108 connects all Penetrates members of the recording head 59a. To the Link K can be one not shown in FIG Suction hose should be attached so that the air duct 108 in the one with preferably a negative pressure loadable suction hose opens. This is preferably outside the web path guided. A led into the receiving opening 61 or threading strips sucked into this is through the air duct 108 in the Hose drained. Through the column S between the Links A to K of the flexible receiving head 59a, So at their joints, when applied the receiving opening 61 with a negative pressure False air is drawn into the air duct 108. Thereby will adhere in an advantageous manner of the threading strip on the inside of the air duct 108 avoided.

Because of the articulated links is the pick-up head 59a shown in FIG flexible in the direction of travel of the web, that is, the Pick-up head can be the routing of the ropes, for example over rollers or rope pulleys, to adjust. At least it is transverse to the running direction so stiff that it doesn't sag or sag and takes essentially the same run, like the ropes 39, 39 '. To sag the recording head due to the eccentric towards the ropes To prevent arrangement of his center of gravity especially in the area between two supports (Rope sheaves), for example Longitudinal tension especially of the inner rope 39 increases become. Other options are before all the inner rope 39 by one or more Supporting or lifting rope pulleys and / or the outer rope 39 'with at least one To push the pulley down.

In the areas adjacent to the air duct 108 the links A to I are drilled 110, the only for reducing the weight of the recording head 59a serve. Also on the inside wall of the air duct - not shown in FIG. 12 - sharp, directed in the direction of flow (arrow 112) Barbs provided an unimpeded Perform the threading strip in the direction of arrow 112 through the air duct, but tear off the threading strip as soon as this against the direction of flow (arrow 112) from the Recording head 59a is torn out. this happens for example when a facility takes over the threading strip from the take-up head, for example around this further through the production plant to transport. With the help of the hook prevents the already in the air duct and possibly part inserted into the hose the threading strip is pulled out again.

In the embodiment shown in Figure 12 the receiving device in which the receiving opening 61 over the hose and the air duct 108 is supplied with a vacuum, this can additionally equipped with a compressed air system be, with the help of compressed air in the air duct and / or the hose can be inserted. Thereby there is an injector effect on the recording head that alone or in connection with a vacuum source the flow at the other end of the hose generated for sucking in the threading strip into the receiving opening is required. The Compressed air device is preferably used if the distance between the takeover area and transfer area and thus the length of the Suction hose is large. The compressed air device can be arranged stationary, that means fixed in the area installed in or within the machine or for example attached to the recording head or in these are integrated.

Figure 13 shows a side view of the recording head 59a according to FIG. 12. It can be seen that the Recording head 59a largely formed flat is. The articulated links A to I have a substantially rectangular shape Cross-section and the links J, K a truncated pyramid Cross-section on being the transition between the links J, K is stepless. To the Link K a flexible hose 47 is attached, in which a spring wire spiral 114 is cast is. The passage opening 116 is preferably special kink-proof, flexible and elastic Hose 47 has a round cross section, the inner surface of the through hole 116 is smooth. The one penetrating the recording head 59a Air duct 108 has in the area of links A to I. a substantially rectangular cross section on which is in the links J and K in the direction of the hose 47 expanded on its cross-sectional area. Due to the relatively small thickness of the recording head 59a into the one that extends into the path of the web Area (links A to I) can be the recording head also by a narrow gap between two Devices, for example between two rollers, be passed through. Because the air duct, starting from the receiving opening 61, in the direction of the tube 47 an expanding cross section has, points through the application the receiving opening 61 generated a high speed so that a particularly safe Takeover and management of the threading strip can be realized.

FIG. 14 shows a side view of the one in FIG. 13 shown recording head 59a, which has a Not shown pulley is guided. The recording head 59a is articulated with each other connected links A to K, the extent of Rope pulley, bent. The radius of curvature the links A to K correspond to the radius of the Rope pulley. As can be seen from Figure 14, the Gap between two links on the inside of the arch practically closed and on the outside Side expanded so that in this position of the recording head 59a the ambient air from is drawn into the column at the top and into the air duct 108 occurs.

Figure 15 shows a front view of the embodiment of the receiving head 59b according to the figures 12 to 14, in which the one with the recording head 59b connected hose 47 outside the web path and the one having the receiving opening 61 Part of the pick-up head 59b projects into the web path, namely in the space 118 between two devices 120, 120 'of the machine, for example Rollers, dryers or the like. The rectangular one Cross-sectional area of the receiving opening 61 is significantly smaller than the circular cross-sectional area of the hose 47. In this embodiment are the recording head 59b and Hose 47 between two guide elements, here Ropes 39 and 39 'arranged at a distance and run parallel to each other. The hose and the ropes are outside of the path and led directly next to the frame 119 of the machine. The ropes with the ones held in between Hose can be used as two endless ropes (double ropes) above the machine for manufacturing and / or processing the web or through the basement the machine from the transfer area to the transfer area and be returned.

As can be seen from FIG. 15, these are only schematic shown recording head 59b, the hose 47 and the ropes 39, 39 'symmetrical to an imaginary, level shown with dashed line E2 arranged in which the longitudinal central axes of the Ropes, the hose and the take-up head.

Figure 16 shows a cross section of another Embodiment of a recording device in Area of a recording head 59c. With the recording head a hose 47 is connected between two identical brackets 122 and 124 one Hose attachment 126 is held. The brackets 122, 124 are by means of fasteners, here Screws 125, releasably connected. The Receiving opening 61 of the receiving head 59c and Through opening 116 of the hose 47 are here - essentially seen in the direction of travel of the web arranged in line one behind the other. Based on these The tube and the receiving head are designed 59c, at least for the most part, in the railway path of the threading strip / the material web. In the embodiment shown in Figure 16 become the hose 47 and the recording head 59c held by two ropes 39, 39 ', which are next to the Recording head 59c on the one facing away from the center of the machine Page between the brackets 122, 124 of the Hose attachment 126 are clamped. The ropes 39, 39 'are also in this embodiment preferably led outside the web path.

All embodiments in which the receiving device at least one, preferably two of Ropes formed guide elements is common, that the ropes at least essentially parallel to the run of the material web to be processed be performed. By tilting rope pulleys / pulleys, over which the ropes are passed can lead them out of the parallel position be, the ropes, optionally with attached hose, parallel to each other stay led. This rope guide is special advantageous if, for example, the suction hose and / or the receiving device based on its dimensions not through the facilities of the production facility, for example a gap between two Rolls can be passed. After one such circumvention of a production device can the ropes then back to the path of the railway parallel route can be returned.

Figure 17 shows a cross section of another Embodiment of a hose attachment 126 'by a pipe clamp known per se is modified. The structure of the hose attachment 126 ', in particular the clamping means 136, is on known, so that only briefly discussed here becomes. The hose attachment comprises two thin-walled ones Half shells 128 and 130 at their ends each have a hook-shaped clamping element. The hook-shaped clamping element 132 of the half-shell 128 forms the half shell with the clamping element 132 ' 130 a pincer-shaped clamping means 134 for a guide element, this from a rope 39 respectively 39 'is formed. The one in Figure 17 is not hose shown is therefore due to this configuration arranged between the ropes 39, 39 '. The upper half-shell 130 is divided into two parts, which by means of a manual actuating means Clamping means 136 are connected to one another. At a Bracing the half shells 128, 130 together, the ropes 39, 39 'in each Clamping means 134 and the hose between them its outer contour clamped half-shells. The width of the hose attachment is 126 ' compared with an advantageous embodiment the diameter of the hose is relatively small.

The attachment of the on the basis of the previous figures described hose 47 on at least one Rope, preferably on the ropes 39, 39 ', can at regular intervals over a defined length of the hose using the hose attachment 126 'or another embodiment of the Hose attachment done. The hose attachment can also be designed in this way, for example be that it clamps firmly on the hose and the ropes, or loose the hose, but tightly clamped on the ropes, or tightly clamped attached to the hose and loosely attached to the ropes is. But it is also possible that the Hose attachment loosely on the hose and the Ropes is attached, here spacers be pushed onto the ropes, each of which Distance between the hose attachments (pipe clamps) determine. The spacers can for example Rings of pearls attached, Pieces of hose and / or spiral spring. These spacers can also be used for hose attachments, which are firmly clamped to the ropes serve to "enlarge" the outside diameter of the ropes, with it the ropes and the hose fastenings run more smoothly over the pulleys. The external dimensions the spacer and the hose fasteners is preferably the same and the transition flowing between these parts, that is, without Edge.

Figure 18 shows a schematic diagram of a clamping device 138 for at least one guide element 35, this is formed here purely by way of example by a rope 39 is. On the rope 39 is a not shown Hose 47 attached at one end to the Receiving opening of a receiving device, not shown is connected and its other end for example with a vacuum source, not shown, for example blower. The tensioning device 138 comprises a T-shaped one here Frame 140 on which two deflection rollers 142 and 144 are rotatably supported and a weight 146 that serves to adjust the longitudinal pull of the rope 39. Furthermore, a deflection roller 147 is on a stationary one Bearing 148 held rotatably. The rope 39 and the hose attached to it are on one Fixed point 150 held by this over the pulley 142, the stationary deflection roller 147 and the pulley 144 out. With a relocation of the rope 39 and the hose in the direction of the double arrow 152, for example a transfer operation the frame 140 in moved vertically up and down. Through the Weight force of the weight attached to the frame 140 146 is simpler and therefore cheaper Way of adjusting the tension of the rope 39 and the hose attached to it.

The tensioning device 138 shown in FIG. 18 can, for example, alternatively to that based on the Figures 1 to 4, 6 and 7 illustrated storage station 45 can be used. The number of rope loops of the tensioning device 138, which is determined by the number of Deflection pulleys is determined can be varied. Of course is the clamping device 138 also for Clamping of several guide elements, in particular Ropes that can be used together over the pulleys be performed.

Figure 19 shows a schematic side view of a another embodiment of a storage station 45 '. The same parts have the same reference numerals provided so that in this respect for description of the previous figures. That with dashed line, of at least a rope 39 formed guide element 35 is in Area of the storage station 45 'over pulleys 154, 156 and 158 managed. On the at least one rope is a hose 47 attachable to a fixed point 150 attached to a hose tray 160 is. The joints between the hose 47 and the rope 39 are shown with points 162. When the rope 39 is shifted in the direction an arrow 164, the hose 47 with the attached to it - not shown in FIG. 19 - Pulling device pulled out of the machine and placed more and more on the hose tray 160. When the rope 39 is moved in the opposite direction Direction, i.e. when inserting the Hose into the machine, this is from the Hose tray 160 pulled out.

In the embodiment shown in Figure 19 the rope is purely exemplary of the rope pulley 154 continued parallel to the hose tray 160, while the hose is being put down.

From the description of Figures 1 to 19 results the procedure mentioned above is straightforward. It consists of the threading strip / the Material web at a speed from the takeover area 5 in the transfer area 7 along the To transfer web path that is less than the speed of the threading strip / the material web itself. In a preferred embodiment becomes the threading strip / the material web during the transfer process in Longitudinal tension, for example with the help a flow leading to the part of the threading strip / the material web, which not from part of the machine to a downstream one Part transferred, but a processing facility is fed.

In the embodiments in which the guide elements of ropes, tapes or the like are formed, it is provided that the open or closed guide system with clamped Hose constantly by a slow back and forth movement, through an oscillation of the guide elements in and against the running direction of the material web be kept in motion. Thereby distribute those acting on the guide elements Influences, for example thermal radiation from the heating / drying equipment or from one Coating device spraying substances, over a larger distance of the guide elements. Furthermore, deposits on the ropes can The guide elements run over the pulleys automatically flake off, causing the guide elements getting cleaned.

An embodiment is particularly preferred the transfer device in which the pick-up head and the hose connected to it opposite the threading strip entering the receiving opening are aligned so that the threading strip its running direction at least essentially maintains. Because the threading strip if redirected a little at all forces on the strip relatively small, so tearing off the strip is practical can be excluded. Alternatively it is possible that the recording head and / or the Hose are designed so that the threading strip in the receiving head and / or in the hose in such a way is redirected that he counter or essentially against the direction of travel of the material web is brought out of the machine. Although this has a reversal of the direction of the threading strip, but can be useful to the recording head faster from its parking position (Figure 1) in the Relocate takeover area.

In an embodiment not shown in the figures the transfer device provided that the guide element as a rack, Rail, tube or the like is formed. The Receiving device is stationary on such arranged guide element arranged movably or can be arranged. With one of it is also a tube formed guide element possible that the recording device within the Guide element arranged or movable is. But it is also possible that the guide element is designed as a role. The reception facility can be done along the path arranged roles, preferably at least partially driven by a drive are relocated.

The individual parts of the transfer device 1 are in an advantageous embodiment executed such that they can be used universally and on each of the two sides or in any running direction of the manufacturing and / or processing machine, So both in left and in Right machines that can be arranged. this is not only beneficial for stocking the parts, but also for the operation of the transfer device, because most of them are in or around Parts / facilities used for the web path too Overhead and around the rollers, rollers and the like have to be led around. Because of this, are the parts / facilities of the transfer device preferably symmetrical or substantially symmetrical executed. This applies in particular to the intake or suction head, the suction hose and the hose attachment (hose / pipe clamps).

It is clear from everything that the invention Transfer device both for transferring a threading strip separated from a material web as well as a material web with its entire Width can be used. The transfer device can be used both in machines in which the material web is continuously managed (on-line), for example in a manufacturing machine, as even in machines in which the material web is not continuous is carried out (off-line), for example in a unwinding station that is used to unroll one serves a roll of wound material web, be used. It is clear that the above described transfer devices that are pure exemplary in the area between two drying groups are arranged, also for example Transfer of a threading strip / a material web from an unwind station to a winding station or from a dryer section along the path through one processing station to another Processing station can be used.

With the help of the transfer device can also Material webs or threading strips with of relatively low strength become. The transfer device further has the advantage that they can be used both for the transfer of very narrow and particularly wide threading strips / material webs can be used. Advantageous is that existing machines are relative can be easily retrofitted. Finally allows the transfer device is automated the transfer process, so that a manual Intervention in the transfer process, for example to remove the committee, not necessary is.

In an advantageous embodiment of the Transfer device in which several cascaded Recording facilities provided are - preferably independent of their constructive design and function- all connected to a common suction system. Further can all reception facilities with the same Treatment facility are connected. The individual reception facilities preferably according to their successive Operation switched on and off.

The control of the entire transfer device takes place automatically in an advantageous embodiment or semi-automatic, for example such that after a web break in the Machine the recording head automatically or by move a manual signal to the transfer position and from there alone a defined, occupies an optimal position. Another signal, for example triggered by an operator or by part of a control unit the introduction of the strip into the receiving opening of the recording head, for example by activation an evacuation. Furthermore is done automatic transfer of the threading strip, the transfer speed being manual or can be varied by the control unit is.
