  • Patent number: 4334403
    Abstract: An open end spinning machine includes a plurality of spinning units. Each spinning unit includes a first yarn breakage sensing device assuming a yarn sensing, operative position, in which it contacts the yarn, when the spinning unit is in a normal spinning operation and an inoperative position, in which it is not in contact with the yarn, when the spinning unit is in a transient condition either from or to the normal spinning operation, and a second yarn breakage sensing device assuming a yarn sensing position at least when the spinning unit is in the transient condition. Upon occurrence of yarn breakage when the spinning unit is in the transient condition, such breakage is detected by the second yarn breakage sensing device and the supply of fibers to the associated spinning unit is interrupted by the second yarn breakage sensing device.

  • Patent number: 4296528
    Abstract: The drawing mechanism comprises a housing accommodating a feed couple defined by a pair of endless belts. One endless belt is mounted about a driving cylinder, and moves in engagement with a movable guide and transmits motion to the other belt running about the pressure roller of the feed couple and said other belt moves in engagement with a stationary guide, and the drawing mechanism also includes a delivery couple defined by its own driving cylinder and its own pressure roller. At the inlet of the feed couple there are mounted a guiding member and a compacting member adapted to precompact the fibrous product being fed into the feed couple. The pressure roller of the delivery couple and the pressure roller of the feed couple, the stationary guide of the feed couple, the compacting and guiding members are mounted on a common removable plate provided with an adjustable retainer means for retaining the common removable plate in its position.

  • Patent number: 4222264
    Abstract: Yarn Y.sub.1, Y.sub.2 being supplied to a textile machine is led over a pair of spaced hooks 24 on a support member 22 and is contacted between the hooks by a pivotable member 12 when in an inoperative position (shown in broken lines). In the event of breakage of yarn, the member 12 pivots into an operative position (shown in full lines) and operates a proximity switch 18 to halt operation of the textile machine. In the event of snatching, the increased tension in the yarn lifts the support member 22 off a magnetic block 26, again causing the member 22 to pivot to its operative position and thereby halt operation of the textile machine. After the snatch has passed, a weight 27 which the support member 22 engages after initial lifting thereof returns the support member 22 to its original position under gravity and the yarn forces the pivotable member 12 back into its inoperative position so that operation of the textile machine can recommence.

  • Patent number: 4117654
    Abstract: Method of and apparatus for the control of composite effect (fancy) yarns with enlargements or "stitches", twisted by means of a hollow spindle. A base thread and an effective thread are combined and fed into the rotating hollow spindle where they are met with a tie thread fed from a package on the spindle. The resulting yarn is fed through pressing rollers past a small hook, through a yarn guide, and thence to a yarn coiling means. A tensiometer is disposed to engage the yarn in the span thereof between the pressing rollers and the small hook. If either the tie thread or the base thread should break, the enlargements on the effecting thread are larger than normal, whereby some of such enlargements are caught by the small hook and the winding of the finished yarn by the coiling means is interrupted. The pressing rollers continue to supply the other threads, and thus there is a reduction of the tension in the span of the thread engaged by the tensiometer.

  • Patent number: 4100722
    Abstract: A method of automatically piecing up a yarn in an open-end spinning machine by rotating the draw off rollers and winding drum in a direction opposite to their normal rotating directions; rotating the feed rollers according to a predetermined program so that the feed rollers begin to rotate after an end of the yarn is moved back into the spinning rotor where the moved back yarn is pieced up with the newly spun yarn; rotating both the draw off rollers and the winding drum in their normal rotating direction, and starting the traverse motion of the traverse guide, which takes place after the pieced joint reaches a contacting line formed between the winding drum and the cheese.By utilizing this method and machine, the number of yarn breakages occuring during starting operation is decreased.

  • Patent number: 4020622
    Abstract: The start-stop program for the open-end spinning machine causes the external suction means to be rendered ineffective during the stopping process before the rotor falls below a speed necessary to maintain tension in the fiber ring in the fiber collecting groove of the rotor. Also, the program causes the external suction means to be effective on the rotor during a start-up only after the rotor has reached a speed sufficient to maintain the fiber ring tensioned in the collecting groove.

  • Patent number: 3991546
    Abstract: A double-twist apparatus has a support provided with a journal in which is rotatably received a sleeve having an eccentric bore in which is centered the shaft of a twist spindle. A whorl carried on the shaft is engageable with a flat belt and rotation of the eccentric spindle within the fixed journal can move the whorl into and out of engagement with the belt. A lever is provided on the sleeve for angular displacement of this sleeve and a spring normally urges the sleeve into a position corresponding to engagement of the whorl with the belt or disengagement of the two. In the case of the spring urging the sleeve into the engaged position a toggle linkage is provided to hold the device in this position. In the arrangement where it urges the whorl away from the belt a spring-loaded device operated by a thread-tension sensor downstream of the apparatus is provided to stop the device in case of thread rupture. A brake is provided on the spindle shaft to arrest it when it is swung out of engagement with the belt.

  • Patent number: 3987610
    Abstract: In order to be able to start-spin on the individual spinning units of an open-end spinning machine under conditions which deviate from the operating conditions and which are, in particular, significantly more favourable for start-spinning, the end of the thread is placed on a ring of fibres located in the spinning rotor at a spinning rotor speed which is reduced relative to the operating speed. At the same time, the sliver feed is reduced in such a manner that the amount of sliver feed corresponds to the reduced speed of the spinning rotor. This reduced sliver speed is produced by a mobile start-spinning unit which is equipped with means which intervene in the drive and/or control of the drive or control means causing feed of the sliver.

  • Patent number: 3967471
    Abstract: In a knitting machine in which upon the application of abnormal tension to yarn, the yarn is released from a yarn engaging element and simultaneously the knitting machine is halted. A yarn replacing apparatus is provided comprising at least one vertical motion mechanism for receiving yarn released from a yarn engaging element and moving it upward into reengagement with the yarn engaging element. The vertical motion mechanism further includes a detecting device for detecting an abnormal condition in the yarn, whereby when abnormal tension applied to the yarn has been removed, the vertical motion mechanism continues to operate, whereas when the abnormal tension applied to the yarn has not been removed, the vertical motion mechanism is halted, and the knitting machine automatically again comes into operation only after the reengagement of the released yarn with the yarn engaging element.
