Abstract

A thread traversing device of a cross-wound bobbin producing machine includes a belt drive having a first belt run with a first thread follower moving in a given traversing direction at a given speed and a second belt run with a second thread follower moving in a direction opposite to the given traversing direction at the given speed, the thread followers having upper ends and being spaced apart by at most twice a given traversing width, and a stationary thread guide for transferring a running thread from one of the thread followers to the other, the thread guide having a concave thread guiding contour touched by the running thread with reversing points defining a traversing path therebetween, the thread guiding contour lifting the running thread at the reversing points over the upper end of one of the thread followers so that the thread is taken along by the other of the thread followers and rides on the thread guiding contour.
