摘要： A yarn withdrawal device for open-end spinning arrangements has a yarn withdrawal nozzle and a balloon-breaking insert which extends the axial channel of the yarn withdrawal nozzle. The yarn withdrawal nozzle has a curved contact surface for deflecting a yarn to be withdrawn and simultaneously rotating the yarn in a crank-like manner, which contact surface graduates from a front surface into the axial channel. The balloon-breaking insert has an inner wall which is provided with raised areas and/or recesses, with which the yarn comes into contact. The contact surface of the yarn withdrawal nozzle is a smooth steel surface. The raised areas and/or the recesses of the balloon breaking insert are such that a yarn hairiness in the range of 3 mm in length is achievable. In addition, values in relation to the spinning stability, tear resistance and evenness can be achieved which are usual in the case of a notched contact surface of standard yarn withdrawal nozzles without a balloon-breaking insert.

摘要： In an arrangement for application in open-end rotor spinning, an opening roller is housed in a swivel housing. The swivel housing can, together with the assembled opening roller, be removed from the arrangement for open-end rotor spinning when the machine is in operation. The opening roller, due to its mass, continues to rotate after it has been separated from the tangential belt which drives it. A locking device is provided which prevents the removal of the swivel housing when the opening roller is rotating. This results in the opening roller being at a standstill when the swivel housing is removed. The risk of injury caused by a still rotating opening roller is eliminated.

摘要： An opening arrangement for an open-end spinning device with a rotating opening roller having opening elements stationarily arranged on its circumference for opening a delivered sliver into individual fibers and for combing out the fibers at a comb-out point. The opening roller has a mechanical stripping arrangement that rotates along with it. The stripping arrangement includes ejectors that are pivotably fastened on the opening roller. Each ejector is arranged between the opening elements and extends over the opening roller transversely in relation to the direction of rotation. The ejector strips combed-out fibers off the opening elements and improves the opening of the opening roller as well as the transfer of the fibers from the opening roller. The opening arrangement is advantageously employed with an open-end spinning frame.

摘要： A spinning device is provided in which at least one sliver is opened to single fiber and the single fiber are deposited on a moveable collecting surface in the form of an air-permeable sieve belt. During transport on the collecting surface, the fiber veil is condensed transversely to its direction of movement to a fiber strand. The now roving-like fiber strand is transported through a nipping line and twisted to a thread by a twisting nozzle.
