Abstract: A piecing method for a spinning machine wherein, following stoppage of the spinning operations, after cutting the sliver (S) between the usually rotating draft rollers (13) and the stopped draft rollers (12) and before the restarting of drafting and spinning, the sliver (S) is once again cut between the usually rotating draft rollers (13) and the stopped draft rollers (12) by driving the stopped draft rollers (12) for a predetermined period of time and then stopping again, thus sliver (S) is supplied to the twisting part (2) by then driving the stopped draft rollers (12). Therefore, not only can the sliver fiber density of the sliver end supplied to the piecing area during piecing be increased, but that length of the tip of the sliver can also be shortened. Accordingly, the strength of the piecing part is increased and the length of the piecing part can be shortened.

Abstract: A method of avoiding constant pattern windings when winding yarn packages by driving traversing yarn guides in accordance with a periodic disruption function, wherein the magnitude of the slope of the periodic disruption function in the vicinity of the extreme points of the function is greater in comparison than the magnitude of the slope of a corresponding sine function having the same amplitude and period. Moreover, the magnitude of the slope of the periodic disruption function changes at least once between a zero crossover and an extreme point, whereafter, until the vicinity of the extreme point is reached, the magnitude of the slope of the periodic disruption function is less than the magnitude of the slope of the corresponding sine function having the same amplitude and period. Preferably, the amplitude and period of the periodic disruption function of the present invention is also randomly varied periodically.

Abstract: An apparatus for heating an advancing yarn is disclosed, which comprises an elongate heater body having a U-shaped channel accommodating a plurality of yarn guides. The yarn guides are configured and positioned such that the yarn advancing through the heating apparatus is deflected along a non-linear path of travel which includes several straight line segments which are closely adjacent and parallel to each of the side walls of the channel. The non-linear path effectively increases the yarn length in the heating apparatus, thereby facilitating high speed operation, and without unduly increasing the frictional resistance of the apparatus on the yarn.

Abstract: A lever (30) is pivotably mounted about ax axis Z on a carrier journal (24) which is pivotable about an axis X and with which electromagnets (46, 48) cooperate. The lever carries a thread-receiving member (20) and is under the effect of a tension spring (42). When the thread is intercepted by the thread-receiving member during the forward rotation of the cop, there follows a deflection of the thread-receiving member, which takes place with the tension spring being tensioned at the same time and which is caused by the thread, on a path approximate to the movement of the traveller on the ring. The tensioned tension spring pivots the thread-receiving member during the paying-out of thread which occurs as a result of the subsequent reverse rotation of the cop. As a result of the intermediate blocking about one of the axes, the thread-receiving member moves on a path lying approximately in a tangential plane relative to the ring.
