Definitions

  • the driving roll which rotates the conical spool by friction, is either mounted on a changing bar and rotated by a lower cylinder, or it is keyed on a changing driving shaft and transmits thus its rotation directly by friction upon the conical spool.
  • the thread fixed on the changing element is arranged in the middle of the crowned driving roll.
  • Fig. 1 shows the arrangement in front elevation.
  • Fig. 2 is a vertical section on line 2--2 of Fig. 1.
  • Fig. 3 shows in elevation partly in section the mechanism effecting displacing of the reversing point of the curve.
  • Fig. 4 is a side elevation of Fig. 1.
  • Fig. 5 is a vertical section on line 5-5 of Fig. 1.
  • the winding bobbin or the conical spool is driven by a raised curved guide rib on a cylinder or on an endless band and extending uniformly in a curve effecting the reciprocating movement of the thread guide.
  • the thread guide is mounted on a reciprocating bar at the middle of the curve guide rib and consequently moved accurately in accordance with the curve.
  • the winding body rolls therefore merely in accordance to a curve corresponding to the movement of the thread guide so that the reciprocating movement of the driving element is omitted in this form of construction, wherefrom results the preservation of the thread owing to the omission of the friction.
  • a sleeve is further arranged, shiftable in axial direction and having on two opposite points rollers guided in oblique grooves in the cylinder, so that at the reciprocating movement of this sleeve effected by a mechanical drive the reversing points of the curve effecting the reciprocating movement of the thread guide are situated on the circumference of said sleeve.
  • the spool b is mounted in the arms of the bow is oscillatably mounted in arms I of the machine frame.
  • the thread guide 71. is fixed on the reciprocating bar a in front of the raised rib d, at the middle of the curved rib said bar g forming a frame guided at the rear end in an upright f and carrying in its lower portion a a roller 1'.
  • the axial shifting of the sleeve 0 on the shaft is effected by a yoke member t engaging in a radial groove of the sleeve 0, which yoke member is mounted on a slide it which is reciprocated by an eccentric u driven by a worm gearing v, w.
  • slide t has pulled out the sleeve 0 owing to the movement of the eccentric u, that is in its extreme right position
  • Fig. 6 shows the slide it in its extreme left position.
  • the sleeve 0 carries on its outer side diametrically opposite rollers p which engage in inclined slots 8 of a sleeve 1' fixed on the cylinder 'n.
  • Both the cylinder n and the cylinder d are keyed on the shaft c and participate in the rotary movement thereof.
  • the sleeve Gil) o rotating therewith is slowly reciprccated by the yoke member at fitted on the slide it and shifted axially on the shaft c.
  • the rollers running in the inclined slots of the sleeve 1' impart additional movements to the cylinder n as the rollers mounted on the sleeve always move in the axial direction or the shaft. These additional movements cause an acceleration and retardation of the speed of rotation so that accelerations and retardations in the reverse of the thread guide occur, so that the reversing points are distributed around the entire circumference of the spool.
  • This machine can evidently be used also for textile machines of any kind and for such machines in which the thread has to be wound on winding spools or any shape, i. e. also on noncylindrical spools, as for instance for twisting machines, for conical cross winding and the like specially for twisting artificial silk.
  • a driving mechanism for conical spools on machines for twisting especially artificial silk comprising in combination with the conical spool, a driving axle, a cylinder on said driving axle, a helical rib on said cylinder in contact with said conical spool, a reciprocating bar between said driving axle and said spool, a thread guide fixed on said bar and extending over said helical rib, a cam on said axle adapted to impart a reciprocating movement to said thread guide and having a groove curved similarly to said helical rib to conform the reciprocating movement of said thread guide to the path or said rib, a sleeve on said driving axle shiitable in axial direction, a cylinder having oblique grooves surrounding said sleeve, and rollers on said sleeve guided in the grooves in said cylinder to shift at the toand fro-movement of said sleeve the reversing points ravens? oi said cam efiecting the reciprocating movement
