Definitions

  • the present invention relates to an important improvement in the warp stop-motion for weaving looms.
  • the present invention solves this problem with completely different methods and in a perfectly simple and efficient way, by highly reducing the risks of twisted yarns and by separating said yarns two or more times, with the same stress thereon as would be imparted by a conventional warp stop-motion.
  • the invention supplies a warp stop-motion for weaving looms, of the type comprising a plurality of rows . carried by the loom and a far larger plurality of blades placed astride of the warp yarns and apt to cause - when dropping on the rows due to breaking of the warp yarns - the stopping of the loom, characterized in that said rows are divided into at least two widely spaced groups, positioned respectively close to the thread carrying roller and close to the healds and being apt to take up, each group independently, positions which can be adjusted both in height and in depth.
  • the warp stop-motion blades are positioned on the warp yarns, in an alternate alignment for each group of rows, by adjacent yarns.
  • figure 1 shows how the rows 1 of a conventional warp stop-motion are arranged substantially at the center of the spacing between the thread carrying roller 2 and 4 the healds 3 of the loom, reference 4 indicating the gauge between the single rows.
  • Figure 2 shows instead the arrangement according to the invention, which provides for the rows to be divided into two groups 11 and 12, of which the first is close to the thread carrying roller 2 and the second is close to the healds 3.
  • the two groups of rows 11 and 12 may be spaced apart to an extent equal to ten - twenty times the gauge 4 between the rows; in the arrangement shown, said groups are positioned at even distances one from the other and in respect of the thread carrying roller and of the healds.
  • Figure 3 shows diagrammatically how the position of the two groups of rows 11 and 12 can easily be adjusted, both in height and in depth, for each group independently.
  • Figure 4 finally shows a diagram of the arrangement adopted for the blades 5 of the warp stop-motion on the warp yarns f: said blades, are positioned on adjacent yarns f, in an alternate alignment for each group of rows 11 and 12.
