摘要： A textile machine includes a cheese or cross-wound bobbin winder with winding stations each having a creel for holding a cheese, a reversible rotary cheese drive, a suction nozzle and a swivel drive for swivelling the suction nozzle to the jacket surface of the cheese. A method for grasping a yarn end resting on the cheese includes adjusting a search time during which the inward-swivelled suction nozzle is positioned at the reverse-rotating cheese, in dependence on the instantaneous diameter of the cheese, and on the reverse speed of the rotary cheese drive, which is kept constant over the entire search time. An apparatus for grasping a yarn end resting on the cheese includes a control device, control lines connecting the reversible rotary cheese drive and the swivel drive of the suction nozzle to the control device, and measured value pickups at each winding station for recognizing a predetermined number of cheese revolutions, for detecting the speed of the rotary cheese drive, and for recognizing the swivelled position of the suction nozzle.

摘要： The invention to a yarn tension sensor, in particular for yarns traveling at high speed, to accurately ascertain even short-term yarn tension fluctuations. According to the invention, a yarn guide element is mounted on one head end of a plunger coil disposed in a magnetic field. A position sensor is disposed in the region of the plunger coil and detects even minimal changes in position of the plunger coil. These changes in position are reported to a controller, at whose output variations in current are generated and supplied to the winding of the plunger coil, the variations being such to compensate for the axial force generated by the yarn and acting upon the plunger coil, thereby making the plunger coil virtually motionless.

摘要： The present invention relates to a brake disk arrangement for a yarn tensioning device wherein at least one of a pair of opposed facing brake disks can be acted upon by a variable pressing force in the direction of the other brake disk. According to the present invention, rotary motion is transmitted from one brake disk to the other in a simple manner, without affecting the brake force, by connecting to one of the brake disks a concentric magnet that is secured against relative rotation with respect to this brake disk, and by connecting to the other brake disk a concentrically arranged body of hysteresis material which is secured against relative rotation with that brake disk. At least the brake disk that can be acted upon the variable pressing force comprises a nonmagnetic material and is changeable in position axially relative to the magnet or the hysteresis material associated with the disk. In alternate embodiments, both brake disks may be provided with a magnet.
