Definitions

  • a device for carrying out slotted leno healds in the making of selvedges in looms having a movable slide which carries pivoted in it a small plate adapted to cooperate with means in the frame of the device for obtaining 21 sure deviation of yarns passing through the plate in the respect of fixed needles of the device through which other yarns pass.
  • the said means fixed .to the frame consist of a single thread guide, for both the. warp yarns not to be crossed, projecting from the frame of the device and the small plate cooperates with it through an extension projecting from the part opposite the one connecting the two holes for the yarns which are crossed.
  • the device according to the present invention comprises a frame 1 provided with a wide prolonged central opening 2 in which there slides a.slide 3.
  • a.slide 3 In a known way it comprises end members 4 for the connection to the healds or heddle bars (not shown), a pair of transmissions 5 with seats 5' for the yarns, a pair of needles 6 ending in tips 7 transversaIly-perforated and spaced apart a short distance in the middle of the frame 1 on the same side from which the transmissions 5 project.
  • the slide -3 which slides within the wide opening 2, carries pivoted on its outer surface a shaped small plate 8 made. of plastic material crossed by two holes 9 lined'with metal rings and having an extension 10 projecting from the side opposite to the one connecting the two holes 9.
  • the said extension emerges from the slide when the holes 9 are aligned with the axis of the slide and of the device frame, but can go back within 'the shape of the slide by making the small plate 8 oscillate on its plane around the pivoting point 8.
  • the extension 10 cooperates with a member fixed to the frame 1 which in the shown embodiment is represented by a thread guide 11 emerging from the frame in the form ofa cubic body crossed by a cylindrical hole.
  • FIGS. 2 and 3 show how, when the slide 3 is brought to the central zone, of the frame 1, the small plate 8 is made to oscillate so that in one direction it takes up the position of FIG. 2 and in the other yarns to the side of the next needle opposite to the preceeding one. This takes place in a positive and safe way without any possibility for mistakes and determines the tying between the yarns F and the yarns f, thus obtaining the desired formation of the slotted leno heald.
  • selvedge warp control means for a loom having 7 a pair of crossing warps and a pair of non-crossing warps, a-pair of aligned needles, one for each noncrossing warp, having their adjacent ends separated by a space, deflector means for thecrossing warps, and guides fixed with respect to the needles on which the deflector means is slidable in a direction generally lengthwise of the needles on one side of said needles from one side to the other side of said space; the improvement in which said deflector means comprises a slide which slides in said direction on said guides, and a plate mounted for pivotal movement on and relative to said slide on the same side of said slide as said needles, the plate having two spaced holes therethrough,
  • each of said crossing warps passing through a different one of said holes and means causing said plate to pivot between operative positions.
  • abutment means comprises a single thread guide for both of said non-crossing warps.
