LOW-INERTIA POSITIVE FEED MECHANISM FOR ELASTOMER YARNS

摘要

A yarn feeder device for feeding elastic (soft) yarns to a yarn consuming station whose yarn demand fluctuations over time has a control unit which ascertains the current yarn demand or to which the current yarn demand is reported. In accordance with this demand, a yarn feed wheel is driven at a rotary speed suitable for the yarn demand. The yarn travels via a tensioning device to the yarn feed wheel. The tensioning device is arranged such that the yarn is stretched in a defined way. As a result, a fixed association between a desired yarn feed quantity and the rotary speed of the yarn feed wheel is possible.
