Definitions

  • the invention relates to a weaving machine, in particular a row shed weaving machine, with stop slats having a stop edge.
  • a weaving machine in particular a row shed weaving machine, with stop slats having a stop edge.
  • Such a machine is described in EP-A-12253.
  • the weft threads are struck by stop lamella combs which are located on the weaving rotor.
  • the disadvantageous phenomenon that a sling comb displaces the fabric at the sling line out of the warp and fabric level can become noticeable.
  • the prescribed shot density is then difficult or impossible to achieve.
  • the warp threads emerge from the slats at some point on the circumference of the slats.
  • the stop edge of the slats which runs in a curve, begins at this exit point. At this point, the stop edge is at a certain angle to the warp and fabric plane. In a known row shed weaving machine of this type, the angle is approximately 30 ° to 45 °. At this angle, the stop edges of the slats can easily displace the fabric on the attachment line from the warp and fabric plane for certain fabric articles.
  • the invention has for its object to prevent the displacement of the fabric at the stop edge in a series shed loom of the type defined. This object is achieved according to the invention by the features specified in the characterizing part of claim 1.
  • the subclaims relate to advantageous further developments.
  • the stop slats are designed in such a way that their stop edge in the stop region runs perpendicular to the fabric plane, so that they cannot displace the fabric from the warp and fabric plane when a weft thread is attached. So that the rotating stop slats can still dive under the tissue after striking, a device is provided which pulls the tissue forward after the stop in the direction of the tissue withdrawal, at least at the circumferential speed of the slats.
  • Fig. 1 shows schematically a weaving rotor 1, which is filled with weft insertion combs and weft stop combs which alternate on the circumference (not shown).
  • specialist training bodies 2 for the high position of the chain
  • specialist training bodies 3 for the low position of the chain.
  • the weft thread just entered takes place at the tip 4 of the compartment through the lamellae of the incoming stop comb.
  • only one stop edge 5 of a stop plate 6 of this comb is shown schematically.
  • the stop edge 5 has a course such that it is essentially perpendicular to the plane of the fabric when the weft thread is struck, as will be described below.
  • the fabric 7 runs along a lower edge 8 of a cylindrical deflection shell 9 and from there via a continuously rotating switching tree 10 and a deflection tree 11 to a (not shown) fabric tree on which the fabric is wound up.
  • the open side 9 'of the deflection shell 9 faces the switching tree 10.
  • the deflection shell 9 extends over the entire width of the fabric and is rotatably supported in the cheeks of the machine with both ends.
  • a control disk 15 is fastened coaxially, which has as many cams as there are stop combs on the weaving rotor 1. Only one cam 16 is drawn.
  • a toggle lever 17 cooperates with the control disk 15 and has a follower roller 18 for the control disk.
  • the toggle lever 17 is rotatable about an axis 19 which is fastened on the machine 20.
  • the toggle lever 17 has an elongated hole 21 in which a pin 22 of a lever 23 is inserted.
  • the lever 23 is clamped by means of a screw 24 on a closed section 25 of the deflection shell 9.
  • brackets 26 are attached to the machine, which have a recess 27 in which the shell rests.
  • the brackets 26 are clamped on an axis 29 by means of a screw 28 and can be displaced thereon in the longitudinal direction.
  • the pin 22 is fastened in a slide 41.
  • the lever ratio of the toggle lever 17 and the lever 23 and thus the deflection of the latter is adjusted.
  • a preferred range for the angle between the stop edge 5 of the lamella 6 and the plane of the fabric extends between 84 ° and 96 °.
  • control disk 15 After loosening a screw 15 ′, the control disk 15 can be rotated with respect to the weaving rotor 1 in order to be able to set the time of the retraction movement of the deflection shell 9.
  • the invention has been described for a row shed weaving machine, it can also be used in a weaving machine with a rotary stop comb, the stop slats lying on a helical line or on a cylinder surface line.
