Definitions

  • the invention relates to a shooter for a wire loom according to the preamble of claim 1, as it has become known from DE-PS 15 35 815.
  • the shooter is equipped with a plurality of weft coils and a guide piece articulated laterally from it for the wires coming from the shooter, in order to arrange all wires in parallel both in the fabric and on the two fabric edges.
  • it is intended to process plastic wire into single or multi-colored fabrics with a simple linen weave, each consisting of several warp and weft wires lying next to one another in parallel.
  • fabrics are widely used as cladding for radiators, room dividers, furniture, sound openings on radio and television receivers and other sound furniture, for covering backrests and side parts of upholstered furniture and the like.
  • wire weaving looms of this type have also proven to be particularly useful for the production of coarse-mesh fabrics from particularly stable and relatively less flexible plastic threads, such as for example for the production of support fabrics made of synthetic thread material for filter cloths in filter presses and the like.
  • plastic threads are extremely stressed under the high pressures occurring in the filter presses and are subject to increased wear. It is therefore important that the plastic threads from which the supporting fabrics are made are also aligned exactly parallel to each other in the direction of the weft threads that are directly adjacent to each other several times and that they are not twisted during the weaving process.
  • the coarse-meshed support fabrics should always have a mesh size that is as constant as possible over the entire area, but this can only be achieved if the strands of weft threads or wires are already inserted into the shed parallel to one another during the weaving process.
  • the shooter because of the axially parallel arrangement of the weft, the shooter must be relatively wide and bulky with a sufficient storage capacity for the weft threads, which on the one hand requires the formation of a comparatively large loom and on the other hand makes the weaving process slow and cumbersome with the appropriate design of the loom.
  • weft wires or threads are not properly reversed from the weft bobbins to the centrally arranged guide piece steered, and also the change of the shot coils arranged parallel to each other parallel to the longitudinal direction of the shooter transversely to the longitudinal direction is cumbersome and time-consuming, since the empty bobbins have to be individually pulled off their axes of rotation and the new bobbins have to be attached individually to each axis of rotation.
  • the invention has for its object the shooter for such a wire loom, which is also suitable for processing coarse threads made of synthetic material, both in terms of the arrangement of the weft coils and in terms of the deduction and guidance of the weft threads or wires up to to improve the guide piece which can be swiveled back and forth by 180 ° and to make it easier to handle.
  • the fact that the shot coils are arranged coaxially one behind the other in the longitudinal direction of the shooter results in a narrower construction of the shooter with at least the same or greater storage capacity of the shot coils used.
  • the individual weft threads can then be drawn off uniformly forwards from each weft spool via the guide roller blocks arranged on the longitudinal side of the contactor without interfering with one another.
  • the swiveling or throwing movement of the guide piece is accelerated and made more precise by the two derailleur rollers provided thereon, when changing the firing direction of the shooter one of the two derailleur rollers is acted upon by the weft wire closest to the finished fabric and under the pulling action of the shooter is caused and a corresponding pivoting of the guide piece.
  • the bobbin change is accelerated and improved quite considerably, since all three or four existing weft coils can be removed from the axis of rotation together and just as easily replaced by new weft coils.
  • the thread take-off from the weft bobbins can be evened out, and a particularly simple bobbin change is obtained if the axis of rotation for the weft coils on one Swivel axis is articulated transversely to the longitudinal direction of the shooter.
  • the axis of rotation can also be detachably connected to the shooter, so that when the bobbin is changed, the shot bobbins do not have to be pulled off the axis of rotation one after the other and pushed back onto the latter.
  • the detachable connection of the axis of rotation to the shooter rather enables a complete exchange of the empty bobbins together with the axis of rotation for a set of shot bobbins pushed onto an exchange axis.
  • the feature of claim 5 also contributes to simplified handling while by the feature of claim 6, the thread take-off from the weft bobbins is improved in that the guide roller blocks have a compensating effect by their resilient mounting against a changing thread pull and always adjust themselves to the changing direction of take-off from the elongated weft bobbins.
  • each guide roller block has at least four guide rollers arranged transversely to the axis of rotation of the shot bobbins, and the guide piece functions particularly reliably when the two additional derailleur rollers on the guide piece are at an angle of approximately 80 ° to 100 ° with respect to the pivot axis of the guide piece and in the pulling direction of the weft wires or threads with respect to the two innermost and the adjacent two outer guide rollers are each arranged approximately in the middle with a gap.
  • the shooter 1 shown in the drawing is intended for a wire loom, which is also suitable for processing correspondingly thick plastic threads.
  • the shooter 1 is equipped with a plurality of weft coils 2 and has on one longitudinal side 1a a laterally articulated, about 180 0 pivotable guide piece 3 with a row of mutually axially parallel guide rollers 5 arranged on both sides of the pivot axis 4 of the guide piece 5 for several weft wires 6 from the weft spools 2 deducted and each time entered in parallel in the shed.
  • the weft threads or wires 6 are then attached to the already finished fabric in the usual way.
  • the shot coils 2 are lined up coaxially one behind the other on a common axis of rotation 7 in the longitudinal direction of the contactor 1 and are supported at the ends by a spring 12.
  • the axis of rotation 7 is pivotally articulated at one end 7a with a bearing eye 8 on an axis 9 arranged transversely to the longitudinal direction of the contactor 1 and is secured at the opposite end 7b by a cover 10 which opposes the direction of pull 6a of the weft threads or wires 6 laterally offset insertion slot 11 for the end 7b of the spool axis 7.
  • the axis of rotation 7 is also supported at its two ends 7a, 7b by two further compression springs 13, 14, which compensate for sudden changes in the tensile force of the coils running from the weft 2 wires or threads 6.
  • Each shooting spool 2 is assigned a guide roller block 15 with four guide rollers 18, 18a, 18b, and on the pivotable guide piece 3 there are at least two further derailleur rollers 19 outside the already existing row of guide rollers 5, 5a, 5b, 5c, which are at an angle 20 of approximately 80 ° to 100 ° with respect to the pivot axis 4 of the guide piece 3 are arranged as an intersection for the legs of the angle 20.
  • the two derailleur rollers 19 are also arranged relative to the two innermost guide rollers 5a and the adjacent two outer guide rollers 5b each approximately in the middle and offset such that when changing the firing direction of the shooter 1 one of the two rollers 19 of the the weft wire 6 closest to the finished fabric, which is passed between the guide roller 5b and the further outwardly adjacent guide roller 5c and tensioned by the pulling action of the protector 1, is acted upon in the pulling direction of the weft thread or wire 6 and a pivoting of the guide piece 3 in the new deduction direction causes.
  • the threads or wires 6 running from the two outer weft coils 2 are first guided around one of the two middle guide rollers 18a on the associated guide roller block 15 and run from there parallel to the coils up to the two outer guide rollers 18b on the spool 2 belonging to the middle weft guide block 15a, from where they are then passed directly between the guide rollers 5b and 5c and on both sides of the derailleur rollers 19 to the outside.
  • the guide piece 3 is provided on its back on both sides of the weft threads or wires 6 with guide brackets 21 pointing to the protection 1, which are curved approximately in the shape of a circular arc.
