Definitions

  • the present invention proposes to improve the working of the warp stop motion device by improving its structure, so that it can be easily adapted to the requirements of each weaving operation, just as if the most suitable positioning were each time chosen for said device.
  • the invention provides for a warp stop motion device allowing, through mutual adjustment of some of its parts, to vary the Lie of the two Laps of the warp yarn chain upstream of the healds.
  • Said warp stop motion device - of the type comprising LateraL and intermediate supports, drop wires for checking the warp yarns, rows interacting with the drop wires, and separation irons - is characterized in that, in each support, the separation irons are mounted on a bracket, pivoted close to the inlet of the chain of warp yarns fed from the beam, said bracket being caused to oscillate along a short arc in respect of said support, and in that, means are provided to Lock the bracket in respect of the support in a given position along said oscillation arc.
  • each LateraL or intermediate support 1 carries - as clearly shown in figure 3 - the rows 2, interacting in known manner with the drop wires 3, which check the yarns f and f' of the warp chain (see figure 2).
  • the separation irons 4 are instead mounted on a bracket 5, pivoted in 6 on the support 1, close to the inlet of the warp yarns f and f' fed from the beam 7 of the Loom.
  • the various supports 1 of the warp stop motion device are stiffened by a tube 8, while a tube 9 mutually connects the brackets 5 of the different supports 1.
  • the tubes 8 and 9 also carry Locking means, consisting of screws 10 and 11, for fixing respectively the desired positions chosen for the supports 1 and the positions of the brackets 5 in respect of said supports 1.
  • brackets 5 in respect of their supports 1 can be adjusted within a short oscillation arc about the pivot 6, as shown in figure 3 wherein the two extreme positions taken up by the bracket 5 are represented by the tube 9, drawn in continuous Lines and, respectively, in dashed Lines.
  • the warp stop motion device according to the invention (figure 2) allows to choose the Lie of the lower Lap over a fairly wide arc, by varying the inclination of the plane tangent to the separation irons 4 and to the tube 9, through oscillation of the bracket 5 - in respect of the fixed part of the support 1 - about the pin 6.
  • Figure 2 shows, in full Lines, the position of strongest inclination of the bracket 5 and it also shows a supplementary tube 12, which prevents the yarns of the upper Lap of the warp from pressing against the rows 2.
  • an equivale nt solution could be to connect the separation irons to the supports and to mount the rows for the drop wires on brackets pivoted to said supports and oscillating to be fixed in a suitable chosen position.
