Abstract
An Apparatus is described for the propagation of the rotary twisting of an open-end yarn from a yarn section in a thread guide to the entwinement point of an open-end spinning apparatus with a spinning element. A provision is made in the longitudinal extent of the thread guide for a thread contact surface, to which surface a vibration element is supplied. The thread contact surface possesses a polished surface and is part of an inlet element on the thread inlet end of the thread guide. The vibration element is connected to a control system, with the aid of which the frequency and/or the amplitude of the vibration generated by the vibration element can be made to match the current operational phase.
