Definitions

  • the idler pulleys of the lifter according to the invention are secured to an axis fixed relative to them and which rotate in bores made in the cheeks of the yoke, which bores therefore constitute a bearing for the rotation of the axes.
  • the pulleys are established in a suitable plastic material such as "nylon" and they are overmolded on a metal axis.
  • the yoke of the lifting beam is preferably produced in the form of two cheeks molded in one piece in semi-rigid plastic material, the internal faces of these cheeks having grooves facing each other facilitating the guidance of the ends of each axis for engage them by slightly spreading said cheeks in the bores of which they rotate.
  • a lifter 1 established in accordance with the invention and comprising a yoke 2 made in the form of two cheeks 3 and 4 joined by a central transverse web 5, so that the yoke is present under the form of a double T whose core is represented by the veil 5 while the two thin and long transverse branches constitute the two transverse parts of the profile in question.
  • the lifter 1 also comprises two pulleys 7 around which a cord 8 passes on the one hand, the two ends of which are subject to the hooks animated by vertical reciprocating movements, while the other pulley is associated with an arcard 9 whose end is fixed and the other is connected to a stringer, not shown, cooperating with a warp thread, as is well known.
  • Each pulley is, as illustrated in fig. 3, made of a suitable semi-rigid plastic material such as a super-polyamide or the like, suitably overmolded on a metal pin 10 (FIG. 3).
  • the periphery of each pulley 7 has a semi-circular groove 7a which receives the cord 8, ie the yoke 9.
  • the axis 10 is provided with a central groove 1 Oa in which the material of the pulley 7 is anchored, so that the latter and the axis are fixed angularly and transversely.
  • the cheeks 3 and 4 of the yoke are also provided with two bores 11 and 12 intended to receive the axis 10 of each of the pulleys 7.
  • the walls of the bores 11 and 12 are, in both cheeks, provided with transverse grooves 11a, 12a extending radially in a centrifugal manner and intended to collect all the impurities which may be between the axis and these bores.
  • the impurities are then stored in the grooves 11a, 12a without them coming into contact with the axis 10 in order to damage it.
  • the two cheeks 3, 4 of the yoke 2 could be established in the form of two separate parts suitably assembled.
