Abstract

An open end spinning machine with an associated service device having a supplementary yarn conveying device utilizing a delivery tube disposed on a delivery tube holder which can be pivoted into various work positions. A yarn guide plate is movably seated in the area of the delivery tube holder and has a yarn guide notch as well as a yarn placement slit and can be selectively controlled by means of a thrust cylinder. By pivoting the yarn guide plate, the yarn extending through the yarn guide notch is transferred to specially designed yarn catch devices of a tube supporting disk seated in a creel of a work station of the spinning machine. Subsequently, the grasped yarn slides automatically into the yarn placement slit which is disposed below the notch and, while being securely guided in the yarn placement slit, is wound as a reserve winding on the empty tube rotating in the creel.
