ABSTRACT:
Apparatus for handling yarn ends during a donning operation on a textile machine wherein in each operation unit, a yarn package is formed on a bobbin rotatably held by a cradle and rotated by the friction roller of a take-up mechanism. Just before or after doffing a full yarn package from the take-up mechanism, a yarn passage is formed by a yarn which is continuously supplied from the operation unit at a position in front of a part of the peripheral surface of the friction roller which the yarn passes over during the normal take-up operation. A fresh bobbin urges the yarn of the yarn passage toward the friction roller and then the fresh bobbin held by the cradle is rested on the friction roller. The yarn connected to the full yarn package is severed during the operation.
