Definitions

  • This invention relates to a device for weighting the press rollers of draw frames in spinning machines.
  • the press rollers are weighted on one maably engaging a draw hook I 0.
  • the hook I! is connected with weighting saddles H on the rollers l2,v I3.
  • Supporting rods M are secured on each side of the machine under the ends of the lever 28.
  • the device operates as follows: or hydraulic pressure medium subjected to regu- The hydraulic or pneumatic medium in the latable pressure.
  • spinning machines are as a hose 6 is p under pr 0 that the 11058 rule double-sided, weighting is usually efiected will expand and force the pressure plates 1 by continuous weights disposed between the two downwardly.
  • This pressure is transmitted to the sides of a draw frame, the ends of the weights double lever 8 and thus to the right and left of being engaged by draw rods which transmit the the machine, with the aid of the rods 9 and hook weight to the draw frames.
  • the present invention constitutes an improvepress rollers l2, I3.
  • the means for'exerting pressure may be placed under the cover of the machine and that only a single means is required for the whole machine. Compared with the known arrangement, this involves a considerable saving and simplifies also the construction of the draw frames. Furthermore, the innovation can be installed in existing machines to get rid of the weights, so that a lot of material can be saved both in new and rebuilt machines.
  • Fig. 2 a plan thereof
  • Fig. 3 a detail view of the roller weighting.
  • a cover 2 is provided between the roller beams l .
  • the beams l are supported by spring pieces 3 the connecting members 4 of which sustain a U-shaped section iron 5 which extends over the entire length of the machine and contains in its cavity a hose 6 for the reception of a pneumatic or hydraulic pressure medium.
  • the hose 6 is sealed at both ends and fitted with means for regulating pressure.
  • Pressure plates 1 resting on the hose 6 act on a double lever 8 whose ends are articulated to draw rods 9 mov- 1.
  • a device for weighting the press rollers of draw frames in spinning machines on both sides thereof comprising a U-shaped section iron disposed under the machine cover between the draw frames on both machine sides, a hose sealed at both ends and arranged in the cavity of said section iron for the reception of a pressure medium, and means connecting said hose with the press rollers of a draw frame.
  • a device for weighting press rollers of draw frames in spinning machines on both sides thereof comprising a U-shaped section iron disposed under the machine cover between the draw frames on both machine sides, a hose sealed at both ends and arranged in the cavity of said section iron for the reception of a pressure medium, pressure plates supported by said hose, a double lever acted upon by said pressure plates, draw rods articulated to the ends of said lever, a draw hook engaged by said rods, said hook being connected with saddles resting on the press rollers, and bars on each machine side for supporting said double lever.
