Abstract: A yarn texturing machine for texturing a plurality of thermoplastic yarns, each in a processing station. The yarns are guided and advanced in each processing station by a plurality of feed systems. One of the feed systems comprises a driven feed roll which is partially looped by the advancing yarn, and a guide member mounted for movement relative to the feed roll for movement between a threading position wherein the yarn is separated from the feed roll and an operating position wherein the yarn engages the feed roll.

Abstract: An apparatus and method for guiding and cutting a continuously advancing yarn (1) during a package doff in a takeup device. The yarn is guided by means of a yarn guide (18) which is movable substantially parallel to a package or to a new tube (13), which is driven by a drive roll (29). Downstream of the yarn guide (18), a deflection device (2) and a suction device (37) are arranged, with the suction device comprising a pneumatic vacuum connection (46) and a cutter (47). The suction device (37) cooperates with a transfer device (42) for purposes of cutting the yarn during a package doff and receiving the loose end of the advancing yarn. To enable a gentle processing of the yarn during the package doff, the yarn guide (18) is arranged in the path of the advancing yarn upstream of the driven tube (13), and a deflection device (2) as well as the suction device (37) are arranged downstream of the driven tube.

Abstract: A yarn texturing machine for texturing a plurality of thermoplastic yarns, each in a processing station. The yarns are guided and advanced in each processing station by a plurality of feed systems. One of the feed systems is mounted on a movable slide, and the slide is guided by means of a slide element along a guide rail and moved by means of a linear drive between a servicing position and an operating position. For a transfer of force, the slide element connects to a drive via a cable line extending along the guide rail.

Abstract: A yarn winding machine for winding a continuously advancing yarn to a package, wherein the package is wound on a tube mounted on one of two winding spindles. The winding spindles are mounted in cantilever fashion for rotation on a spindle turret. To be able to perform a yarn transfer from a full package mounted on one of the winding spindles to an empty tube mounted on the other winding spindle by rotating the spindle turret, the winding machine includes a yarn transfer device, which is rotated from an idle position to a deflecting position. The deflecting position is defined by a stop arranged on the spindle turret, so that during the rotation of the spindle turret the deflecting position is varied according to the rotation of the spindle turret.

Abstract: For pushing packages (7) from a winding mandrel (4) of a takeup apparatus (1), an ejector is provided, which has a piston arranged for reciprocating movement in a cylinder (8) by supplying a pressure medium. The piston is a magnetic piston, whose polarity is opposite to that of at least one magnet connected to a push unit (9). The push unit (9) is displaceable substantially along the cylinder (8) with the movement of the piston.

Abstract: A yarn winding machine for winding a plurality of yarns on a corresponding number of winding tubes. Each winding tube is associated with a contact yarn guide in a contacting position for threading the yarn. By means of a threadup device which includes, a threadup yarn guide moving along a guideway and stationary contact yarn guides, the yarns are distributed from a threading position to the contacting position. Between the threading position and the contacting position, the yarns are guided by the threadup yarn guide and distributed, one after the other, to the contact yarn guides.

Abstract: A yarn false twist texturing machine having a vertically adjustable device for threading and guiding the advancing yarn at a location between the heater and the cooling plate of the machine. The threading and guiding device comprises a tubular casing having a rodless magnetic piston mounted for sliding movement therein, and a magnetic sliding element and a yarn guide mounted for sliding movement on the outside of the tubular casing. The polarity of the magnetic sliding element is opposite that of the rodless magnetic piston so that the magnetic sliding element follows the movement of the magnetic piston, and the magnetic piston is moved by compressed air delivered into either one or both ends of the tubular casing.

Abstract: A yarn false twist texturing machine in which an advancing yarn is deflected by a feed yarn guide at a deflection position which is between a heater and a cooling member, and which is at an elevation outside the reach of the machine operator. The feed yarn guide is height adjustable, and it is disposed on a sliding element, which is movable upwards and downwards on a guide rail by means of a linear drive. In the event the electrical energy supply of the machine fails, the linear drive is activated by means of a control device in such a way that the sliding element and the yarn guide move downwardly to a predetermined parking position just below the yarn deflection position, so as to automatically remove the yarn from the heater and thereby prevent yarn damage.
