ABSTRACT:
A device for automatically spinning-in yarn in spinning units of open-end rotor spinning machines improves the process of leading the spinning-in head of the device onto the take-off tube of the spinning unit by using simple means.
According to the invention the spinning-in head is attached to a swing lever by attaching means kinematically firmly in the plane of its swing motion but resiliently in the direction perpendicular to said plane, in order to allow the spinning-in head to move across the mouth of said take-off tube while being lead by a lead-on cone.
