Definitions

  • Leather belt drawing frames according to the principle of Casablanca generally comprise, apart from a pair of feed rollers and a pair of drawing rollers, a pair of leather belts which are driven by two rollers positioned at the entrance of the sliver and guided, in the moving direction of the sliver, around two guiding rods.
  • very favorable conditions are thus created for drawing the silver in the drawing frame between the nipping points formed by the leather tape rollers on the one hand and the two following drawing rollers on the other hand.
  • the adjustable auxiliary device or deflecting member Arranged in the cage between the middle rollers B, 9 and the guide rods III, II is the adjustable auxiliary device or deflecting member which is shown in the form of a round rod or roller device l2, the two preferably square shaped end portions of which may be selectively engaged in any of the spaced recesses H of variable depth in the two cage plates H in such a manner that the round rod l2 exerts more or less pressure in an upward direction at a suitable point of the operating sides of the leather belts and thus deflects the operating side of the lower leather belt more or less from a straight direction.
  • My invention will permit in future to admix with cotton, cellulose wool of much greater length of staple, irrespective of the length of staple of the cotton material, whereby the strength of such mixed yarns can be considerably increased.
  • a drawing frame comprising a pair of feed rollers, a pair of drawing rollers, a pair of endless belts intermediate said rollers, means for driving and guiding said belts at their return points, plates on both sides of said belts for supporting said driving and guiding means, a rod-shaped member adapted to support the upper side of the lower belt at a point intermediate said return points, and recesses in said plates for adjustably mounting said rod-shaped support member.
  • a drawing frame comprising a pair of feed rollers, a pair of drawing rollers, a pair of endless belts intermediate said rollers, retiu-n members of constant spacing for said belts, plates at both sides of said belts for supporting said return members, a rod-shaped member adapted to support the upper side of the lower belt intermediate said return members, and spaced communicating recesses of difierent depth in each of said plates adapted to selectively receive the ends of said support member.
  • a drawing frame comprising a pair of feed rollers, a pair of drawing rollers, a pair of endless belts intermediate said rollers, means for driving said belts, means for guiding each of said belts at one of its return points, a rod-shaped member adapted and arranged to exert a degree of pressure against the operative band sides of such belts along a line intermediate their respective return points so as to create an auxiliary nipping line between said feed rollers and drawing rollers, and a plurality of means each effective to maintain said rod-shaped member in fixed position relative to the belt with which it is in contact, and arranged in different positions lengthwise of an operative band side and thus effective to maintain such rod-shaped member in different positions lengthwise of such band side, and making possible a change of position of the auxiliary nipping line.
  • each corresponding pair of openings being arranged and adapted to hold suchrod-shaped member in a position different from that in which it can be held by any of the other sets.
