  • the seam weaving machine according to the invention consists of two opposing mirror-image and otherwise identical machine halves M, M '.
  • the elements of this machine half are each provided with the same reference number, the reference number of the half shown in FIG. 2 being provided with a dash.
  • the machine half M, M ' only the one element in question is described and numbered; the description and numbering automatically apply to the same element of the other machine half.
  • the Getell G is slidably mounted on guide rails 2 on guide rails 2 and can be moved by means of a stepping motor 3 from one end of a textile web 4 to the other end, normally 4 to 8 m.
  • the fabric ends of a fabric 7 to be woven together are stretched to the right and left of the clamped warp threads 8 onto a tensioning device 9.
  • a tensioning device 9 On this clamping device 9 is the frame G with the two machine halves M, M 'and Jacquard machine slidably mounted.
  • the fabric ends are clamped in such a way that the corresponding weft threads 10 (warp threads in the previous weaving process) of one fabric end lie opposite the weft threads 10 'of the other fabric end.
  • the seam weaving compartments 11 to be formed one after the other are formed with the jacquard machine 5.
  • the weft thread 12 to be woven is inserted into the corresponding seam weaving compartment 11 with the aid of the seam weaving machine M, M 'according to the invention, pushed in with the sley 6 and integrated by forming a new seam weaving compartment 11' corresponding to the seam weaving process.
  • the weft thread 12 'to be woven is introduced into this newly formed seam weaving compartment 11' with the aid of the seam weaving machine M ', M, pushed in with the sley 6 and integrated by forming a new seam weaving compartment 11.
  • This sequence of operations of inserting the weft threads 12, 12 'which are respectively to be woven in with the aid of the seam weaving machine M, M' into the correspondingly successively formed seam weaving compartments 11, 11 ' is repeated until the weave seam 13 is completed.
  • the symmetrical halves M, M 'of the seam weaving machine shown in FIGS. 2 and 3 are constructed symmetrically to the weave seam 13.
  • weft threads 12, 12 ' are spatially separated with the aid of disk separators 14.
  • the workflow is identical on the right and left side of the seam weaving machine M, M '.
  • Each disk separator 14 rotatably mounted in the frame G, shown in FIGS. 4 and 5, essentially consists of a separator shaft 15, an inlet disk 16, a threaded part 17, 18 and an outlet disk 19.
  • the threaded part 17, 18 consists of individual disks of different thickness and outside diameter, the thinner disks 17 having a larger diameter and the thicker disks 18 having a smaller diameter.
  • the thickness of the washers 18 is dependent on the diameter of the weft threads 10 to be processed, and the thickness of the larger washers 17 is dependent on the spacing of the individual warp threads, now weft threads 10, in the fabric 7 from one another.
  • the difference in diameter between the thinner and thick washers 17, 18 must be so large that the weft threads 10 structured by the weaving process fit into the individual threads of the thread formed from the washers 17, 18 without deformation of the structure.
  • the thread-like structure 17, 18 arises from the fact that the individual disks 17, 18 are correspondingly cut and pre-bent at their outer edges. This deformation of the disks 17, 18 can take place by means of a cutting and bending device 20, which can be seen in FIG. 31.
  • a thread is thus created, on which the weft threads 10 individually drawn in by the inlet disk 16 are transported only in a certain rotational range of the disk separator 14. So that such a thread-like structure can be achieved, the individual disks 16 to 19 must be attached to the separator shaft 15 and additionally to the guide rods 21 in the following manner.
  • the outlet disk 19 which is supported on a collar 22 of the separator shaft 15. Following the outlet disk 19 comes first a thick disk 18, then a thin disk 17, etc. So many thin and thick disks 17, 18 are pushed onto the separator shaft 15 and respective guide rod 21 in the order described until the required thread length is reached is. Finally, the inlet disk 16 is pushed onto the separator shaft 15 and guide rods 21. After the individual disks 16 to 19 have been placed on the separator shaft 15, they are clamped against the collar 22 formed on the separator shaft 15 by means of a clamping ring 23 and a clamping nut 24. The desired transport of the weft threads 10 takes place on this thread-like structure 16 to 19 in a certain rotational range.
  • One of the guide rods 21 is flattened on a surface line and lies with the flattened side against the separator shaft 15, cf. Fig. 5. This measure serves the purpose of always ensuring that the thread pitch is always the same.
  • the shape of the face milling on the clamping ring 23 and the outlet disk 19 depends on the required thread pitch and direction of the pitch and thus again on the diameter of the weft threads 10 and the direction of rotation of the disk separator 14.
  • the disc separator 14 of the machine half M makes a clockwise rotation limited to 360 ° and then intermittent, while the disc separator 14 'carries out the same counterclockwise rotation, as seen in the weaving direction.
  • This rotary movement which interrupts after one revolution, is generated by a stepper motor 25 (FIG. 2).
  • the respective direction of inclination of the thread-like structure 16 to 19 on the disk separator 14 is achieved by corresponding milling on the face side on the clamping ring 23 and the outlet disk 19 and by corresponding cutting and pre-bending of the disks 16, 17, 18.
  • the pitch direction of the thread on the outlet disk 19 corresponds to the pitch of the remaining thread 16 to 18.
  • the individual pulling in of the weft threads 10 onto the disk separator 14 is achieved in that the incision 26 made by the cutting and bending device 20 provided washer 16 is exactly the same as the thin washers 17 of the thread-like structure 17, 18, with the only difference that a segment is cut off from the incision 26 on the washer 16 parallel to this incision 26 (shown in FIG. 6) ), so that a kind of knife edge 27 is created.
  • This measure interacts with a first weft thread guide 28 responsible for the entry of the weft threads 10 and with a second weft thread guide 29 serving for the exit.
  • Each weft guide 28, 29 consists of a bar provided with a knife edge aligned against the separator 14, which can be displaced both vertically and axially, the first weft guide 28 being longer than the second weft guide 29, while the first weft guide 28 around the outlet side a length dimension that exactly corresponds to the width of the outlet disc 19.
  • the outlet disk 19 located at the end of the thread-like structure 16 to 18 is designed in such a way that the weft thread 12 to be woven is spatially separated from the weft threads 10 still located on the threads. This spatial separation takes place in the axial direction by means of a special thread 30 cut on the outlet disk 19 with a large pitch. Furthermore, a milling 31 (FIGS. 3 and 7) on the circumference of the outlet disk 19 enables the weft thread 12 to be taken over by a gripper 32 (FIGS. 2 and 3).
  • This gripper 32 is designed like a crank (FIG. 2); his crank member is swung out by a stepper motor 33 in the cycles of the weaving process.
  • the stepping motor 33 is fastened to a cantilever 34 of a guide rod 35 which can be displaced longitudinally axially on the frame G and which is moved back and forth in the weaving direction in the rhythm of the weaving process.
  • the longitudinal displacement of the guide rod 35 takes place by means of a further stepping motor 36.
  • the free end of the gripper 32 describes a spatial curve which it spends from the outlet disk 19 to the entrance of the respective seam weaving compartment 11.
  • a fabric guide 37 made of sheet metal is arranged on each half of the machine, by means of which both fabric ends of the fabric 7 are opened against one another in a funnel-shaped or conical manner and are thus prepared for the separation of the weft threads 10.
  • the arrangement of the disk separator 14, which is rotatably mounted in the frame G, and the fabric guide 37 (see FIG. 7) ensure that the knife edge 27 (FIG. 6) on the inlet disk 16 directly at the foot of the protruding from the fabric 7 and with a the additional weave 38 (FIG. 2, also FIG. 7), which has come about as a result of the partial weaving described above, engages weft threads 10 provided on the outer edge.
  • This procedure enables the weft threads 12 to be woven in to be clamped at their front ends by the respectively assigned gripper 32 (FIG. 1).
  • the grippers 32 are guided on the space curve described above in such a way that the respective front end of the respective weft thread 12 clamped by the associated gripper 32 is brought past the disk separator 14 and the first weft thread guide 28 at the level of the respective seam weaving compartment 11.
  • a turning of the guide rods 35 is prevented by means of keys 40.
  • At the rear end of each guide rod 35 a set of teeth 41 is attached.
  • the rotary movements of the stepper motors 33 and 36 are coordinated.
  • the plug-in arm 43 ' must be located within the cavity formed by the fabric 7 to be woven, because otherwise the insertion of the plug-in arm into the seam weaving compartment 11 would not be spatially possible.
  • the plug-in arm 43 with the weft thread clamping device 44 takes over the weft thread 12' from the gripper 32 'and pulls it through the seam weaving compartment 11'.
  • the weft thread clamping devices 44 it is also possible to push the weft thread 12 with the plug arm 43 only up to the middle of the weaving shed 11, where the weft thread is then taken over by the plug arm 43 'of the machine half M' and finally pulled through the seam weaving shed 11.
  • the weft thread 12 'is then passed through the corresponding seam weaving compartment 11' in the same way.
  • Each plug arm 43 is provided with a toothing 45; the required straight-line oscillating movement takes place via the toothing 45 in that, as already mentioned, the plug-in arms are mounted in the frame G such that they can rotate and are driven by stepper motors 46 which perform reversing movements.
  • the weft threads 12 each inserted into the corresponding seam weaving compartments 11 are pushed with the weaving drawer 6 onto the weaving seam 13 that has already been completed.
  • the sley 6 is rotatably mounted in the frame G and is driven by a stepper motor 47, as shown in FIG. 8.
  • the weaving strips 38 separated from the weft threads 10 by the thermal cutting devices 39 are wound onto the winding rollers 49 with the aid of the stepping motors 48.
  • the woven strips 38 still connected to the weft threads 10 are firmly connected to the clamping device 9 at the end of the clamping device 9 by means of clamping devices 50.
  • the frame G is displaceably mounted on guide rails 2 and is displaced from one end of the fabric band to be woven to the other end during the weaving process.
  • This shift takes place step by step, namely in the cycle of the seam weaving process, in that the frame G is moved step by step by the stepping motor 3 via a tooth connection 51, 52.
  • a logic circuit (not shown) and carry out their method steps in the cycle of the jacquard machine, a series of intermediary sensors (not shown) controlling the entire workflow in a manner known otherwise.
  • the disk separator 14 described here takes up a number of weft threads 10 in the course of the separation in the manner of a memory. Because the disk separator 14, which is driven by the stepping motor 25, rotates step by step in the cycle of the weaving process, the separated weft threads 10 travel over the thread-like disks 16 to 18 from the inlet disk 16 to the outlet disk 19, where - as already described - the weft yarn 12 arriving there is picked up by the gripper 32.
  • this separator can only be used economically for fabrics with equally strong fabric threads.
  • a simpler disk separator 53 must be used for economic reasons.
  • This consists of a ring 54, on the outer surface of which a metric thread 55 corresponding to the direction of rotation of the disk separator is cut, as well as an inlet disk 16, a single thicker disk 18 and an outlet disk 19.
  • the inlet disk, thicker disk and outlet disk are designed as in the previous embodiment described.
  • the metric thread 55 on the ring 54 has the task of preventing the weft threads 10 from being taken along in the feed direction of the seam weaving machine during the advancement of the seam weaving machine and thus the weft thread 10 not always being drawn in by the run-in disk 16 onto the disk separator 53.
  • the basic arrangement of the disk separator 53 in the seam weaving machine is shown in FIG. 9.
  • the release of the weft thread 12 to be woven in from the binding of the weaving strip 38 is achieved by correspondingly raising and lowering auxiliary warp threads 56 by means of auxiliary lifting elements 57 articulated on the jacquard cords, which are controlled by the jacquard machine 5.
  • the released weft thread 12 is spatially separated from the weft thread 10 with the aid of the outlet disk 19.
  • Both disc separators 14, 53 require extremely precise guidance of the fabric to be woven in relation to the seam weaving machine, approximately in the order of magnitude of 0.1 mm, both in the individual step from thread to thread and in the sum of the process steps from the beginning of the fabric band and up to it The End. This means that the seam weaving machine must be able to handle the individual step errors at all times to cancel each other out, a requirement that can only be met by means of complex sensor technology.
  • the spatial separation of the weft threads and their subsequent guiding down to the respectively formed compartment is accomplished by an air flow coming from an air nozzle 58 (FIG. 10).
  • the weft thread 10 integrated in the woven strip 38 is brought together with the woven strip from a woven strip guide 59 to the air nozzle 58, the woven strip 38 being brought out of its original vertical position into an approximately horizontal position.

  • the woven strip 38 is fastened to the clamping device 9 outside the seam weaving machine. During the operations of weaving the fabric ends together, the weaving strip 38 stands still while the frame G moves with the seam weaving machine.
  • the derogatory auxiliary warp threads 56 of the web strip 38 are wound onto the winding roller 49. Since the respective web strip 38 must be guided exactly from thread to thread relative to the seam weaving machine when disc separators 14, 53 are used, it is absolutely necessary that the take-up roll 49 is stretched exactly in time with the seam weaving method, which controls the driving stepper motor very precisely 48 requires.
  • auxiliary warp threads 56 which are no longer used on the winding roller 49 and are no longer used, are held in tension by means of an unwinder roller 68 which is connected to the winding roller 49 in an axially and rotationally fixed manner, around which the rope 67 is wound on which the drive weight 66 depends.

  • the weft thread 12 is separated and guided up to the plug-in arm 43 'by means of air flow, liquid flow or electrostatics, regardless of the accuracy of the guide steps. This significantly simplifies the control of the seam weaving machine.
  • the woven strip 38 does not need to come about exclusively by partially weaving out the textile web 4, but can instead take in auxiliary warp threads 56 that are woven into the fabric and are foreign to the fabric. This measure means that you are no longer bound to the specified number of stems for the type of tissue.

  • Predefined wave structure of the warp threads 8, originally weft threads, and the weft threads 12, originally warp threads, are positively prevented.
  • each individual type of fabric requires a special weaving drawer 6; however, the manufacture of a woven drawer is quite complex.
  • the sley 6 has only one task of pushing the respective weft thread 12 onto the seam 13. Since it is not possible to move the now warp threads 8 and the now weft threads 12 against one another even with the seam weaving compartment 11 still open due to the thread structure, in a further embodiment of the invention the pushing of the weft thread 12 onto the woven seam 13 can also be carried out using a needle roller rotatable in the frame G. 100 (Fig. 21), which can be used in the same shape for all types of tissue.
  • the needle roller 100 which is rotatably mounted in the frame, essentially consists of a shaft 101, on which two opposite rows of needles, consisting of a plurality of flexible needles 102, are arranged helically along their longitudinal axis are.
  • the first of these helical, opposing rows of needles is right-handed and the second opposite row is left-handed.
  • the needle roller 100 is driven by a stepper motor 103, wherein it executes a rotary movement which is limited to 180 ° in the cycle of the weaving process and then stops.
  • the individual needles 102 of the needle roller sweep past the weft thread 12, originally warp thread, which is added to the weaving seam 13 and leave scratch marks on it. Such scratch marks can possibly cause damage to the fabric tape in the area of the woven seam 13.
  • the weft threads 12 can be pushed into the seam weaving compartment 11 by means of Z-shaped needles 104, which are arranged next to one another in a guide bed 105, are individually axially displaceable and reach into the seam weaving compartment at their front Z end (FIG . 22).
  • the guide bed 105 is fixedly connected to the frame G and consists of a base plate 106 and two guide rods 107 fixedly mounted in this base plate 106, onto which rigid bend plates 109 and spacer sleeves 110, which are alternately provided with two bores 108, are pushed, whereby first a plate 109, then a spacer sleeve 110 follows on each guide rod 107. etc., lastly a sheet 109.
  • Each spacer sleeve 110 has a length corresponding to the cross section of a Z-needle 104 and thus enables the longitudinal axial displacement of the associated Z-needle from one spacer sleeve 110 to the next.
  • the height distance of the guide rods 107 in the region of the base plate 106 spanning the woven seam 13 is dimensioned such that the Z needles 104 fit in between the base plate 106 and the lateral surface of each of the spacer sleeves 110 pushed onto the guide rods 107 without play (FIGS. 22 and . 24).
  • This construction of the guide bed means that the Z needles 104 can be moved back and forth in the weaving direction in a manner that prevents rotation.
  • the displacement of the Z needles 104 for the purpose of pushing in the weft thread 12, originally warp thread, introduced into the corresponding seam weaving compartment 11 takes place against the seam weaving direction by means of a link 111 with an arcuate in the first third of the total length of the link 111 perpendicular to the seam weaving direction, in the second third arcuately against the seam weaving direction and in the last third again groove 112 machined at right angles to the seam weaving direction, the total length of the link 111 being three times the width of the weaving seam and the individual Z needles 104 engaging in the groove 112 with their rear end.
  • the backdrop 111 is slidably mounted on two special backdrop guide rods 113 at right angles to the seam weaving direction.
  • the link guide rods 113 are mounted on one side of the base plate 106 in a sliding element 115 which is displaceable in the base plate 106 in the seam weaving direction and biased against the seam weaving direction by an adjustable compression spring 114 (coil spring or compressed air cylinder).
  • the common displacement of the two link guide rods 113 and thus also the link 111 mounted on them is therefore necessary so that the gradual advance of the frame G does not have a tolerance-related effect on the insertion of the weft thread 12, originally warp thread, introduced into the seam weaving compartment 11 onto the woven seam 13 can have (Fig. 26).
  • the link 111 is fixedly connected to a toothed belt drive 116 (or rope drive) and is shifted by the latter with the aid of a stepping motor 117 in the cycle of the seam weaving process from the corresponding side of the seam 13 to the other side and vice versa.
  • the Z-needles 104 bent in a Z-shape and engaging with the rear end in the groove 112 of the link 111 in succession each perform an axial shift corresponding to the groove path up to the woven seam 13 and back to the starting position.
  • the link 111 described above has the disadvantage that a relatively high friction occurs due to the deflection of the needle ends in the arcuate central part of the groove 112 between the Z-needles 104 and the link 111. This friction leads to increased wear and also to an increase in the drive power for the link 111.
  • the axial Displacement of the Z-needles 104 is no longer effected by the arcuate curve piece of the groove 112 in the second third of the total length of the link 111, but by a rotatable roller 118 used instead of the curve piece (FIG. 27).
  • the drive power for pushing in the weft thread 12, originally warp thread can be compared the sley 6 conventionally used in weaving technology and also lowered relative to the needle roller 100.
  • the jacquard machine 5 has a sufficient number of cords 119, it is possible to achieve a three-stage lifting of the warp threads 8.
  • the cords 119 of the jacquard machine 5 are connected to one another by connecting the first cord with the six hundredth cord, the second cord with the six hundredth cord, the third cord with the five hundred and ninety-ninth cord, and so on, for example with a number of cords of 601 cords .
  • the interconnected cords 119 form loops which run around a summing roller 120. This device shortens the time course of the seam weaving process by about half without the working speed of the individual functions of the seam weaving machine having to be increased (FIG. 28).
  • a special cord 122 is attached to an axis of rotation 121 of the summing roller 120, in which a main lifting element 123 for the respective warp thread 8 is inserted. In the further course of the cord 122, it is guided around a rotatably mounted deflection roller 124 and fastened to a tension spring 125 suspended in the frame G.
  • the jacquard machine 5 is controlled in a known manner by punch cards.
  • the jacquard perforated card in question is punched according to the rhythm of the weaving process and makes it possible to raise the main lifting element 123 in three stages and thus simultaneously to form two seam weaving compartments 11, 11 ', the seam weaving compartment 11 being formed above and the seam weaving compartment 11' below the weaving center (shown in Fig. 29).
  • a second jacquard machine 126 can be attached in addition to the jacquard machine 5, which are rotatably connected to one another via a common shaft 127.
  • the cords 119, 128 of the two jacquard machines 5, 126 are now cross-connected from machine to machine according to the principle described above, for example by B.
  • the first cord 119 of the first jacquard machine 5 can be connected to the corresponding first cord 128 of the second jacquard machine 126 etc.
  • the simultaneous formation of two seam weaving compartments 11, 11 'then takes place as described above, in that the punch cards of the two jacquard machines 5, 126 are matched accordingly.
