摘要： A method and apparatus for piecing up yarn on an apparatus for producing wrap yarn. The device includes delivery rolls, a hollow spindle, takeup rolls, and a wind up device. A binding thread is fed from a bobbin carried on the hollow spindle for wrapping around a fiber bundle being fed through the delivery rolls and the hollow spindle. A clamping device and yarn guide is provided for positioning a piecing thread into the nip of the delivery rolls for being joined with said fiber bundle upon breaking of the wrap yarn.

摘要： A method and apparatus for detecting the faulty working of spinning units of an open-end spinning machine by monitoring the faults in yarn as it is fed from the spinning machine. An electrical signal is produced by a sensor indicating faults appearing in the yarn. Another signal of predetermined frequency corresponding to the speed of delivery of the yarn from the spinning machines is generated. The electrical signal produced by the sensor is electrically multiplied by the signal of predetermined frequency for producing a differential signal. This differential signal is filtered, shaped and integrated and subsequently compared with a preset threshold value for producing a signal indicating when the occurrence of faults exceed a predetermined threshold. This signal can be used for stopping the spinning unit.

摘要： Transmission of the thread twist-forming force to the thread end is facilitated by a finger mounted eccentrically in the bore of the thread drawoff tube. The thread, which is rotated about the circumference of the bore, periodically engages the finger, which finger plucks the thread away from the tube wall and momentarily relieves the bearing force between the thread and the drawoff tube at the tube infeed end. The finger is spaced inwardly from the tube infeed end and may be a pin projecting radially inward from the tube wall or an offset wire extending parallel to but eccentrically of the tube axis.
