Definitions

  • the present bobbins and the like used in the textile industry comprise a tube on which the yarn is zigzag wound up in a great many superimposed layers.
  • an initial thread supply is wound up at the tube end, a supply which protrudes from all of the manufacture or member.
  • this supply is wound up at the winding beginning, manually holding the thread for some time out of the normal path for the thread guide.
  • the present invention having the purpose of improving the evenness and practical execution for the above operation, comprises a drum, at the periphery of which the thread is caused to rest in order to start the thread supply on the tube, the drum being fast with a threaded spindle turning with minimum friction within a bushing restrained on the machine frame and which may also axially slide therein for a length corresponding to the drum height, at its end projecting from said bushing, said spindle terminating in a portion acting as a pushbutton for causing the axial sliding; this drum being protected by a housing from which it can completely protrude when said pushbutton is axially urged and into which housing it can completely reenter when said spindle, owing to the drum rotation due to thread friction, is entirely threaded within its bushing, thereby disengaging the thread from the drum for commencing the normal winding up of said thread on the tube.
  • FIG. 1 shows an axial sectional view of the device, wherein the drum is fully retracted within its housing.
  • FIG. 2 is also an axial sectional view showing the device, wherein the drum is fully projecting from the housing.
  • FIG. 3 is an enlarged view showing the detail of the mechanism allowing the threading and axial sliding of the spindle.
  • FIG. 4 is a top plan view showing the drum and housing.
  • FIG. 5 is a side view of the device as mounted on the machine for winding up the thread supply on the tube.
  • FIG. 6 is a top plan view showing the device when winding up the thread on the tube.
  • the device (FIGS. I and 2) comprises a drum 1, on the periphery of which a thread 17 (FIG. 6) is caused to rest for starting the thread supply 15 on the tube 1 l.
  • the drum is fast with the threaded spindle 2 (FIGS. 1 and 2) threading with minimum friction within the bushing 10 which, in turn, is restrained on the machine frame 12 by screw thread 23.
  • the threaded spindle 2 may also axially slide within said bushing, moving upward through a length corresponding to height h of said drum 1 (FIG. 2) and raising the pushbutton 4 which is attached to the lower end of said spindle.
  • the drum is protected by the housing 3 carrying a thread guide shaft 8, from which it can completely protrude (FIG. 2) when said pushbutton 4 is axially urged in the direction of arrow 25, or into which housing it can completely reenter (see FIG. 1) when, due to the rotation of said drum as imparted by thread 17 (FIG. 6), is fully threaded within its bushing 10.
  • the threaded spindle 2 threads within the bushing 10 (see FIG. 3) through a rolling member comprising in the particular example shown a ball 5 on one side partially entering the spindle screw thread and on the other side resting and reacting against the inclined wall 10' of the frustoconical cavity 19 within the bushing 10 and connected with an overlying cylin- 9, projecting therefrom at the lowermost position (FIG. I).
  • the device is carried in advance of main thread guide 6 (FIGS. 5 and 6) laterally of tube 11 and is manually loaded by urging the pushbutton 4 in the direction of arrow 25 (FIG. 2).
  • thread 17 starting the building up of supply 15 on tube 11, passes about thread guide shaft 18 and rotatably drives said drum 1, thus causing said threaded spindle 2 to be threaded within its bushing 10 and resulting in the lowering of drum 1 until fully reentering its housing 3 (FIG. 1).
  • thread 17 is free, or disengages from said drum, being no more capable of gripping thereon and now the thread is grasped by the thread guide 6 to start its regular winding up on tube 11 and providing the manufacture.
  • a device for winding up the initial thread supply at the end of a bobbin comprising a rotatable drum, and means mounting the drum for axial movement into an extended position in which a thread passing between a supply of thread and a said bobbin can pass about and rotate the drum, and a retracted position in which the drum is out of contact with the thread
  • said mounting means comprising a screw-threaded spindle within a bushing, said spindle carrying said drum and being freely movable in said bushing toward said extended position, and means engaging between the bushing and the screw-threaded spindle to engage in the screw thread of said spindle to restrain movement of said spindle toward said retracted position to helical movement whereby rotation of said drum under the influence of said thread returns said drum to said retracted position.
  • a device as claimed in claim I and a housing from which said drum projects in said extended position and into which said drum retracts in said retracted position, said housing disengaging the thread from the drum in said retracted position.
  • said engaging means comprising a rotatable member engaging between said screw thread and an inclined surface on said bushing whereby said screw thread overrides said rotatable member when moving toward said extended position, said rotatable member being urged by said inclined surface against the screw thread during movement toward said retracted position.
