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 process for rejoining the thread on an open-end friction-spinning device, in which fibers are fed into a V-shaped nip subjected to suction, and the thread formed in the V-shaped nip is drawn off from this and wound onto a bobbin. For rejoining, the fiber feed into the V-shaped nip is interrupted and a thread end drawn off from the bobbin is guided towards the V-shaped nip counter to the spinning direction. This thread end is paid out in front of the V-shaped nip and is stored in a joinable length in a storage station at the end of the V-shaped nip facing away from the bobbin. The bobbin is then advanced towards its drive roller and the thread is drawn off from the storage station. After a predetermined time after the start of the thread draw-off, the fibers are fed again into the V-shaped nip, where they come up against the thread end running through the V-shaped nip and are twisted together with this.

摘要： The invention concerns and open-end spinning device having two friction rollers driven in the same direction and forming a spinning notch, whereby at least the friction roller rotating towards the spinning notch is made as a suction roller, conveying the fiber material fed onto its casing surface into the spinning notch. According to invention, a collecting groove for the arriving fiber material is provided at a distance from the spinning notch, said groove being constituted by the casing surface of the friction roller rotating towards the spinning notch and by a moving guiding surface. According to the invention the surface speed of the guiding surface in the collecting groove is synchronized with the surface speed of the friction roller.

摘要： In a friction-spinning process, the fibers (30) are twisted together on a thread formation line (43) as a result of the rotation of two friction elements (1, 10) driven in the same direction and forming a V-shaped nip and are drawn off as a thread (4). For piecing, the thread (4) is returned into the piecing position outside this thread formation line (43) and only then is placed in the thread formation line (43). During the run-off of the thread (4) from the friction elements (10), the pressing force of the thread (4) against at least one of the friction elements (10) is increased. For this purpose, a thread guide element (5) is arranged directly after the friction elements (10) and is movable transversely relative to the thread draw-off direction (42).
