Definitions

  • a pattern disruption device in a crosswinding machine, includes a crosswinding spool, a rotational memher in frictional contact with said spool for effecting rotation thereof, means for intermittently driving the member and means for varying frictional contact between the crosswinding spool ancl the rotational memher.
  • the invention relates to a pattern disruption device for crosswinding machines wherein a crosswinding spool is rotated by means of an intermittently driven rotating member in frictional contact with the periphery thereof.
  • Such devices have as their objective the prevention of the formation of so-called pattern windings which are produced on the spool periphery during the wind ing operation from time to time, preferably, however, within specific diameter ranges.
  • the prior art devices of this general type are no longer sufficiently effective for the high take-up speeds that are to be attained nowadays and that are also permissible for the yarn material. Furthermore, these devices effect the build-up or wind-up and thereby the unwinding properties of a crosswinding or crosswound spool in an undesirable manner, since particularly the yarn guiding reliability is weakened and in consequence thereof a great number of irregular yarn layers is produced. Additionally, in the case of higher contact pressures a sufficiently effective slip or backlash between the crosswinding spool and the rotational member is no longer available.
  • a pattern disruption device wherein the crosswinding spool and- /or the rotational member are so disposed that the frictional contact between the crosswinding spool and the rotational member is intermittently varied.
  • the frictional connection therebetween intermittently by varying the compressive force.
  • the crosswinding spool is accordingly not fully lifted off, but rather is stress-relieved by being raised.
  • the contact of a crosswinding spool with the driving rotational member is always maintained so that the yarn guiding reliability, especially, is not deteriorated in any manner.
  • the change of the frictional contact takes place in synchronism with the intermittent drive of the rotational member so that the intermittent drive of the rotational member occurs in the same rhythm as the intermittent variation in the frictional contact.
  • the change in the frictional contact it is also advantageous and in accordance with the invention, for the change in the frictional contact to be effected in counter-:synchronism to the intermittent drive of the rotational member so that, for example, the frictional contact between the rotational member and the crosswinding spool decreases when the driving connection has been restored and the frictional contact increases whenever the driving connection has been interrupted.
  • FIG URE of the drawing which is a schematic, elevational the invention.
  • a crosswinding spool 1 being wound with a thread F coming from a supply coil or cop 27.
  • the crosswinding spool 1 is driven peripherally by a rotational member 2, which is in the form of a yarn guiding drum.
  • the drive of the rotational member 2 is rotated by a continuously driven driving roller 3, which rotates with constant rotary speed through a friction roller 4 which is intermittently pivotable into and out of position between the drive roller 3 and the rotational member 2.
  • the intermittent motion is produced by an oscillating pivot shaft 5 and transmitted through a lever 6 and a rod 7 to a rocker arm 8.
  • the rocker arm 8 is supported by the upper portion 28 of a sensing member 29 and thereby rocks a rocking lever 9, a rod 10 and a bell crank 11.
  • the rocking movement is ultimately transferred to the friction roller 4.
  • the change in the frictional contact between the crosswinding spool l and the rotational member occurs in synchronism with the intermittent drive of the rotational body through the frictional roller 4. Consequently, an additional lever 13 is fixedly connected to the oscillating shaft 5.
  • the lever 13 is connected to a tension rod 14 to which clamping member 15 and 16 are secured.
  • the clamping members 15 and 16 serve to hold and adjust tension springs 18 and 19 which, in turn, are suspended from the lever end 17 which is pivotally mounted at 34.
  • the frictional roller 4 is brought into operative engagement through the rod 6 as well as the other component members described hereinbefore.
  • a force is simultaneously exerted on the lever end 17 through the tension rod 14 and the tension springs 18 and 19, the force remaining ineffective, however, as long as an arm 20 engages a pawl 21.
  • the crosswinding spool attains a predetermined wound diameter, however, it can then, through a cam segment 23 fixedly secured to the spool frame 22, swing the pawl 21 about the pivot 24 thereof and withdraw the arm 20 from its point of contact.
  • a spring 35 biases the pawl 21 in a clockwise direction about pivot 24 as shown in the drawing.
  • the lever end 17 can now be swung away counterclockwise about pivot 34 by the tension spring 18 so that the detent 25 is brought into engagement in a gap between adjacent teeth of a tooth segment 26, also fixedly secured to the spool frame 22.
  • the detent 25 is pivotally mounted on lever 17 at 30 and has a lug 31 adapted to contact lever 17.
  • the lever 17 has a projection 32 and a spring 33 between the projection 32 and detent 25 which biases the latter in the position shown in the drawing.
  • the spool frame 22 and thereby the crosswinding spool 1 are stress-relieved by the adjustable force of the tension spring 18.
  • the cam segment 23 in the exemplifled embodiment is provided with four tooth-shaped contours which are associated with four diameter ranges within a crosswound spool, wherein the change, in accordance with the invention, of the frictional contact between the crosswinding spool 1 and the rotational member 2 are to be effective.
  • the crosswinding spool 1 is shown in the drawing just before a first pattern zone is attained. We claim:
  • a pattern disruption device comprising means supporting a crosswinding spool, a rotational member in frictional contact with said spool for effective rotation of said spool, means for intermittently driving said rotational member, and contact varying means for varying the magnitude of the frictional contact between said crosswinding spool and said rotational member while maintaining continuous physical contact between said crosswinding spool and said rotational member, synchronizing means operable to provide that the intermittent drive of said rotational member by said drive means occurs in a predetermined time relationship with the variation in magnitude of the frictional contact between said spool and said rotational member, wherein said synchronizing means operate in counter synchronism so that the magnitude of the frictional contact between said spool and said rotational member increases when said intermittent drive of said rotational member has been interrupted and decreases when said intermittent drive of said rotational member has been restored.
  • said contact varying means includes means responsive to a given range of diameters attained by said crosswinding spool during the winding of a thread thereon, whereby said contact varying means is actuated only during predetermined diameters of said crosswinding spool.
  • said contact varying means comprises biasing means and an actuating device for altering the contact pressure between said spool and said rotating member.
