Definitions

  • crowd training devices have existed for a long time which include knives moving in opposition in a reciprocating movement to cooperate with the hooks of a multiplicity of control systems for heddles or arches, said hooks being connected by a cord which passes around the first pulley of a block. Its second pulley is surrounded by a cord, one end of which is secured to the frame, while the other is associated with at least one stringer.
  • a cord which passes around the first pulley of a block. Its second pulley is surrounded by a cord, one end of which is secured to the frame, while the other is associated with at least one stringer.
  • Crowd-forming devices of this kind allow a certain opening of the pitch which is of the order of 100 mm. If one wishes to increase the importance of this step, for example for the manufacture of carpets or other fabrics, one attaches the free end of the above-mentioned cord to a yoke in which is mounted a mad pulley guiding a funicular element whose one end is fixed relative to the frame of the device, while its free end is associated with at least one stringer.
  • the two-pulley block and the idler pulley must be offset longitudinally so as not to interfere. Likewise, it is necessary to guide them longitudinally to avoid their collision with the corresponding members of neighboring systems.
  • the improvements which are the subject of the present invention aim to remedy these drawbacks and to allow the production of a simple crowd training device, of small overall size and of economic cost price.
  • a mad pulley is rotatably mounted in the block which thus comprises three pulleys, the funicular element passing from its anchor point successively around the idler pulley or third pulley of the muffle, then around a deflection pulley whose yoke is fixed, to then surround the second pulley of the muffle and finally hang vertically in order to be associated with at least one stringer or arch.
  • Fig. 1 and 2 illustrate, in the low and high position respectively of the crowd, one of the systems used until now.
  • FIG. 3 and 4 are views similar to those of FIG. 1 and 2, but illustrating a crowd training device established in accordance with the invention.
  • Each system comprises two identical hooks 1 each comprising two branches 1 a and 1 b , the free end of the first of which is provided with a hook 1 c , while that of the other short branch 1 b has a spout 1 d .
  • the crowd training device behaves in the manner known two knives 2, 3 which move in opposition in a back-and-forth movement to raise or lower the hooks 1 which rest in their free state on the bars 4 of a grid not shown by means of their beak 1 d .
  • the two hooks are joined by a cord 5 passing around the first pulley 6 of a block or lifter 7.
  • the second pulley 8 of the muffle 7 is surrounded by a cord 9, one end of which is anchored at a point fixed 10, while its free end carries a collar connected to the corresponding rail.
  • the free end of the cord 9 is associated with a yoke 11 carrying a mad pulley 12.
  • a funicular element 13 one of the ends of which is fixed relative to a point 14 of the frame of the device in question, its free end carrying a collar 13 is associated with a heddle or harness 15.
  • the cord 9 and the funicular element 13 are replaced by a single funicular element 20, one of the ends of which is anchored at a fixed point 21.
  • the element 20 successively surrounds the idler pulley 17, then the return pulley 18, it then rises to pass around the second pulley 8 of the block or spreader 16 to then hang vertically so that its free end carrying a collar 13 a is associated with a heald or arch 15.
  • the diameter of the pulley 17 is smaller than that of the pulleys 6 and 8 and is located below these, while the diameter of the return pulley 18 and its position are such that all the strands of the element 20 are oriented parallel to each other.
  • a crowd opening A is obtained identical to that defined by the systems of FIG. 1 and 2, but with a height gain B of the crowd forming device of approximately 170 to 200 mm, that is to say close to the value of the opening A of the crowd.
  • a height gain B of the crowd forming device of approximately 170 to 200 mm, that is to say close to the value of the opening A of the crowd.
  • the cord 5 is attached by its ends to the two hooks of a crowd-forming device such as that described in French patent 2,583,045.
  • a crowd-forming device such as that described in French patent 2,583,045.
