Definitions

  • 'I'he present invention relates to winding machines and more particularly to a method and means for automatically initiating the winding operation on Winding machines.
  • the said length of thread projecting out of the bobbin is torn off by hand, in order to bring the weft bobbin into a condition suitable for weaving purposes.
  • a length of thread from the beginning of the thread to be wound is placed into a revolving thread clamp which turns about the axis of the thread carrier at a reduced speed relatively to the speed of the thread carrier, whereby a traction is exerted on said length of thread by the thread windings forming on the leading thread carrier, said traction causing the length of thread to be pulled out of the thread clamp and wound into the package to be formed on the thread carrier.
  • Said length of thread accordingly is invisibly xed in the interior of the finished package.
  • Fig. 1 is an axial section through the drive for the winding spindle and the thread clamp, and
  • Figs. 2 to 6 are perspective views illustrating the initial stages of the winding operation.
  • the Winding spindle I of a weft winding machine is mounted in a bearing sleeve 2, carrying at its rear end a cone disc 3, which serves for coupling the spindle with a drive shaft (not shown) connected to the driving gear of the machine in any conventional manner.
  • the bearing sleeve 2 extends through a bushing 4, which is mounted in a wall 5 of the machine frame.
  • the rear end of the bushing l contains a needle bearing 6 supporting the bearing sleeve 2, while a ball bearing "l serving for the same purpose is disposed in the front end of the bushing It.
  • the cage 8 of the ball bearing I is flanged at 2a to form an outer, enlarged cylindrical extension 8b, completely surrounding a ball bearing 9.
  • Airing le] is engaged over the winding spindle I and secured to 'it by means of a cross pin Il.
  • the ring lil forms a front abutment for the ball bearing S, the inner race 9a of which abuts with its opposite end against one end of the inner race la of the ball bearing l; the other end of this inner race 'la bears against a shoulder 2a formed on the bearing sleeve 2.
  • the winding spindle I carries a driving disc I2 having a friction coating I3 for engaging the correspondingly enlarged end of a weft bobbin A, which according to Figs. 2-6 is slipped on the spindle I for windingpurposes.
  • An outer sleeve Iil is secured to the cylindrical extension 8b of the ball bearing 9 and provided with a iiange Illa at its outer end remote from the ball bearing 8; the flange lila carries a small plate I5 fastened thereto at its center by a rivet IE.
  • the small plate I5 is bent upwards at both ends, so as to form two thread clamping positions at the flange Ida of the sleeve I4.
  • the cone disc 3 transmits its rotary movement unchanged to the winding spindle I, and the inner race la of the ball bearing 1, rigidly secured to the bearing sleeve 2, likewise turns at the full speed of the winding spindle I.
  • the balls of the ball bearing I operate as planetary friction members, turning in the same direction as the spindle I and transmit their movement of rotation with considerable reduction, for example, at the rate of 1 :2.5 with respect to the speed of the associated inner race la, by the intermediary of the ball cage 8 and the cylindrical extension 8b thereof, to the outer sleeve I4, Which consequently has a speed correspondingly reduced with respect to the winding spindle I. Accordingly, the winding spindle I rotates faster than the double thread clamp, formed by means of the small plate I5 at the outer sleeve I.
  • the winding thread B (Figs. 2 6) is inserted with its free end (beginning of thread) into one or the other of the two thread clamps .3 formed by the plate l5 on the outer sleeve I4 (threading sleeve).
  • the vthread B is automatically wound on the thread fcarrier ⁇ A Irigidly held on the winding spindle l (Fig. 3).
  • rllhe drive vfor vthe revolving thread clamp l5, llullen-of Ecourse may also ⁇ be ⁇ effected in any other manner than by a ball-orfother planetary drive, as for instance lover va gear wheel-or .belt drive, in order to obtain the desired difference in speed -between'the .bobbin spindle :and Ithe thread .clamp vor the advancing of the thread carrier relatively ⁇ to the thread Clamp, without departing from the spirit -vof the -invention or the ⁇ scope of the appended claims.
  • a winding machine having a winding spindle, a revolving Athread clamp arranged to turn about the axis-of .said winding spindle .and adapted to engage a length of )thread from vthe beginning of the thread to be wound on .said thread carrier, a common .driving member for ,said spindle and thread clamp, and movement transmission means operating to turn said thread clamp with ,a smaller speed than said winding spindle, whereby the length of thread engaged in said thread clamp is automatically pulled out o'f the Aclamp 'by the thread carrier and wound into the package to be formed on vthe thread carrier.
  • the method of automatically initiating the winding operation on winding machines having rotating thread carriers which consists in placing a length of thread from the beginning of the 'thread to be wound into a revolving thread clamp, :and 'turning -the thread clamp about the axis of the. revolving thread carrier at a reduced speed 'with respect to the speed of the thread carrier, whereby ,a traction is exerted on said length of thread "by 'the v.thread windings forming on the thread carrier, said traction causing the length of thread to be pulled out of the thread clamp and1wound'intcthe package to be formed on the thread carrier.
  • a winding'spindle In a winding machine, a winding'spindle, a package receiving thread carrier engaged on the vwinding spindle, a revolving thread clamp arranged to turn about the axis of said winding spindle' and :adaptedto engagea length of thread .trom the beginning of the thread to be ⁇ wound on said thread carrier, ,a .common driving member for said spindle .andthreadclamp and movement transmission :means operating to turn -said thread clamp with a smaller speed than said winding spindle, whereby the ⁇ length of thread Vengaged 4in said thread clamp is automatically pulled' out of the clamp by the thread .carrier :and wound into the Apackage to be formed yon Ythe threadcarrien :3. .A winding machine as claimed in claim .2,
  • said ymovement transmission means includes a planetary .motion train imparting ⁇ a reduced speed to l:said revolving vthread clamp.
