Definitions

  • the present invention relates to a device making it possible to bring the warp threads into three different positions by means of several claw frames movable vertically.
  • the high and low positions are reached respectively when the two hooks are retained by the claw frame and their vertical stroke is equivalent to that of said frame.
  • the intermediate position is established when only one of the two hooks is engaged with the claw frame, which allows the collar to be displaced by half of the vertical stroke of the previous case.
  • the second pulley blocks of the mittens are surrounded by a cord with fixed ends and which encircles the first pulley with a third muffle, the other pulley of which is encircled by an arch wire at a fixed end.
  • BE-A-529 019 a three-position armor mechanism, the arch of a hook of which passes around a mad pulley mounted on a fixed axis and then on a mad pulley of a block, the another pulley is moved by a neighboring hook.
  • the hooks 1 and 2 are constituted by a main branch 1 a and 2 a straight whose upper end is provided with a spout 1 b and 2 b , while its lower end is curved to form a second branch 1 c , 2 c vertical, provided with a hook 1 d , 2 d cooperating respectively with a bar 5 a and 5 b of the grid 5 constituting the bottom board.
  • Each of the branches 1 a , 2 has hooks 1 and 2 passes through the ring of a press needle referenced 6 a , 6 b and 7 a , 7 b which in the known manner allows the spouts 1 b to escape, 2 b to the knives 3 a , 4 a when you do not want the hooks to be gripped by these knives.
  • connections 1 e , 2 e of the branches 1 a , 1 c respectively 2 a , 2 c of the hooks 1 and 2 are connected by a cord 8 passing around a pulley 9 a of a block 9.
  • a pulley 10 freely rotating about an axis 11 secured to the frame 12 of the armor mechanism.
  • the second pulleys 9b of two flasks 9 of the two devices A and B, and the pulley 10 are surrounded by another or arcade cord 13 whose one end 13a is attached to a fixed point 12 a of the frame 12, while that its other end 13 b carries a carabiner 14 constituting the collar to which at least one heald 15 is attached.
  • a double hauling is thus carried out, making it possible to obtain the three desired positions of the collar 14, that is to say a low position corresponding to the lower position of the warp threads (fig. 1), a horizontal or intermediate position of these (fig. 2 ), and an upper or upper position of these wires (fig. 3).
  • the arms 1a of the devices A and B are pressed so that the knife 4 has not grip the spouts 1b when the corresponding part of claws 4 mounts.
  • the hooks 2 are pressed so that their beak 2 b is not driven by the knife 3 a corresponding to the frame of claws 3 when it rises after being lowered.
  • the collar 14 remains in the low position and all the hooks 1 d , 2 d of the devices A and B rest on the bars 5 a , 5 b of the grid 5.
  • the average position shown in fig. 2 is realized in that one presses alternately the branches 1a, 2a of the hooks 1 and 2 of the device A, so that the hooks 1 d, 2 d are in abutment against the bars 5a, 5b of the grid 5. On the contrary, the beaks 1 b , 2 b of the hooks of the device B remain in engagement with the knives 3 a , 4 a during the back-and-forth movement of the claw frames 3 and 4.
  • a module 16 comprising a multiplicity of vertical partitions 16 a , 16 b etc., between each of which are crowd-forming devices A, B, C, D .., each constituted by two hooks 17, 18 connected by a cord 19 surrounding the first pulley 20 a of a block 20 guided between the partitions considered.
  • an idler pulley 21 is provided, the axis of rotation 21 a of which is fixed to a horizontal wall 16 c of the module 16.
  • the second pulleys 20 b of the mittens 20 of two devices A and B of the module 16 and the idler pulley 21 are surrounded by a cord or arch 22, one of the ends 22 a of which is anchored to a fixed point 16 d of the module, while the other end 22 b carries a carabiner 23 constituting the collar to which at least one heald 24 is attached.
