Definitions

  • the invention relates to a method for producing a plug-in seam for making a fabric band endless according to the preamble of claim 1 and claim 4. It also relates to a seaming machine for carrying out the method.
  • the fabric belts of the type mentioned at the outset include, in particular, drainage or dryer fabrics.
  • sieves with a plug seam have the advantage that they can be made endless in the dewatering machine or in the dry part of the paper machine even by joining the two prepared fabric ends with a plug wire.
  • the production of these plug-in seams has so far been done by hand, by weaving or splicing back the warp wires on each fabric side of two fabric ends to be sewn, so that a row of warp wire loops is formed on each side, through which the common, connecting plug wire can then be guided.
  • the object of the invention is therefore to provide a method and a machine which make it possible to mechanize or automate the cumbersome and time-consuming manual work and thereby noticeably relieve the workforce and thus increase the productivity and the quality of the plug seams to reach.
  • the method according to the invention consists in that, after the right and left side of the fabric have been frayed, the warp thread ends are lined up in a magazine band, mechanically separated in accordance with the weaving order and individually woven back around a loop of a wire spiral, with the use of two wire spirals paralleling them lie and are not connected to each other, and wherein the left and right ends of the tissue are held so that a lateral sliding or shifting is prevented.
  • the wire spirals are then connected with a common jumper wire outside the sewing machine.
  • a suturing machine which is characterized by thread separators arranged on both sides of the plug-in seam to be produced for separating and separating the warp thread ends from the warp threads arranged in magazine bundles on each side of the fabric, a gripper system consisting of transfer grippers and pull-through grippers for inserting the triggered single threads in an auxiliary thread pre-formed weaving shed in which the single threads can be struck against the respective fabric edge by a driven sley per seam half, whereby after striking the single threads through the hook system either around one or more central wires or wire spirals or while avoiding the central wire or wires Wire spirals can be woven back into their own fabric side.
  • the sewing machine is mounted on a chassis 1, consisting from a frame body 31 which is movable on wheels 30 and which can be moved in the rhythm of the weaving progress via a controlled drive motor 2.
  • the frame body 31 is guided below the working plane of the machine on both sides on two parallel guide tubes 3, which in turn are attached at their ends to a horizontal cross member 32 of a stand 4. All other operating elements of the sewing machine according to the invention are also mounted on the chassis 1, not all of which are described in detail, since they are not necessary for understanding the workflow or the method.
  • the shed forming device 5 as one of these operating elements is connected to the chassis via a console 6.
  • the switching and monitoring devices necessary for operating the sewing machine which are not shown, are attached to the console 6.
  • thread separators 7, 7 'and transfer grippers 8, 8' are fastened to the console 6 or to the shedding device 5 for both fabric halves or sides, the reference numerals provided with the line index referring to the one half of the fabric and the reference numbers not having the line index belong to the opposite other half of the tissue.
  • the pull-through grippers 9, 9 'and the two weaving frames 10, 10' are mounted below the working level of the sewing machine.
  • the screen fabric 11 to be provided with a pin seam is carried out under the seaming machine, i. H. the machine rolls on the screen covered with a protective layer. Another possibility of guiding the screen fabric 11 is shown in FIG. 2.
  • the screen fabric is then passed over the seaming machine like a tent via two support rods 23, 24.
  • the two ends 21, 22 of the screen fabric 11 to be provided with a stitching are prepared before insertion into the seaming machine as far as the weft threads are removed in an area of approximately 10 to 20 cm width and then, depending on the weave, 10 to 30 weft threads on the Warp thread ends 12, 12 'are combined in their exact weaving position to form a magazine band 13, 13'.
  • a wire bundle which can consist of original weft threads of the fabric or a strip 15, 15 'consisting of original weft threads of the fabric, also called auxiliary warp strip, which represents the chain for the seam weaving process which runs transversely to the actual sieving direction.
  • the central wire 16 is located exactly in the middle between the two auxiliary chain strips 15, 15 '.
  • the auxiliary warp strips and the central wire are fastened in a further tensioning device 17 of the machine, which is also carried by the stands 4, 4 '.
  • the individual wires of the auxiliary chain and the central wire are guided in eyelets of the shedding device 5, which is located above or below the weaving plane on the chassis.
  • the separation and separation of the warp thread ends 12, 12 '(FIG. 1) with the aid of the thread separators 7, 7' is carried out in a manner known per se, with seam forming elements of the same type on both sides, such as thread separators 7, 7 ', transfer grippers 8, 8', Pull-through grippers 9, 9 'and shutters 10, 10' are provided.
  • the transfer rapier 8 takes over the warp thread separated from the thread separator 7' and swings it down into the transfer position of the working plane, as can be seen in FIG. 3.
  • the pull-through gripper 9 takes over the warp thread end and pulls the warp thread into the full compartment formed by the shedding device 5.
  • the warp thread end thus entered is then struck against the selvedge by the sley 10 '.
  • a partial compartment is formed, as can be seen in FIG. 4, and the same warp thread end is pivoted back by the pull-through gripper 9 into the transfer position mentioned, where it is taken over by the pull-through gripper 9', the transfer gripper 8 'during the transfer process positioning aid by pressing of the warp thread.
  • the connector compartment is formed in the auxiliary warp thread half 15 ', the next warp thread is brought from the transfer gripper 8' into the transfer position and is inserted by the pulling gripper 9 into the part compartment now located outside, as can be seen from FIG., After which the warp thread is again struck with the sley 10 ' .
  • the central wire 16 Since the central wire 16 is not involved in the change of subject during these operations, it is not wrapped around by the warp wire ends. This is shown in Fig. 6 by the threads or wires a and b. Then the operations described above are repeated in the same order with the following wires or threads b and d, but this time the central wire 16 is included in the change of subject and thus in the warp wire loop. Thus, only every second warp thread of each fabric end forms a load-bearing warp wire loop 33, 33 'that can transmit longitudinal forces.
  • a single central wire 16 it is also possible to weave in a plurality of parallel plug-in wires, for example two Plug wires 27, 27 ', as shown in Fig. 7, whereby the seam strength is increased because all the warp threads of the fabric protrude in contrast to the seam shown in Fig. 6.
  • the use of two plug wires takes into account in particular the fact that in a frequently used four-ply, so-called double-layer fabric, the loops turn out to be alternately long and short due to the natural thread offset, as shown schematically in FIG. 7 for a simple fabric.
  • the two fabric ends 15, 15 ' are offset from one another such that a long loop 28 of the left screen fabric edge with a short loop 29' of the right screen fabric edge around the right plug wire 27 'and a short loop 29 of the left screen fabric edge with a long loop 28 'of the right sieve mesh around the left plug wire 27 can be combined.
  • a process variant can be used in such a way that the warp thread ends are individually woven into a loop 34 of a wire spiral 25 after the fraying of the right and left side of the fabric and their alignment in the magazine band each warp wire end binds into the spiral, as shown in Fig. 8.
  • This device is required in particular when using two parallel wire spirals 25, 25 ', one of which is assigned to a screen fabric side. These two wire spirals are not connected to each other.
  • the left and right tissue ends are held by the device 18 by means of guide rollers 19, 20 in such a way that lateral slipping or shifting is prevented. Then the wire spirals are connected with a common plug wire outside of the sewing machine.
  • the seaming machine described above is designed in such a way that it can also weave a wire spiral 25 of the type shown in FIG. 1 into only one side of the fabric.
  • a wire spiral 25 of the type shown in FIG. 1 into only one side of the fabric.
  • the wire spirals which are later connected to a common plug wire when the screen is made endless, together with a wire 26 (FIG. 10) lying in the spirals into the fabric ends.
  • the sewing machine is suitable for technical fabrics, such as. B. dryer fabrics for drainage, paper and board machines of various compositions in the warp and weft directions (mono or multifilament in polyester or polyamide) and single or multi-layer construction with pin seams ' .
  • Basic fabrics for wet felts in single or multi-layer designs can also be provided with pin seams.
  • the auxiliary warp threads in the seam area that is to say the weft threads in the original fabric, consist of a different material than the other weft threads in the fabric.
