ABSTRACT:
A device for handling wound bobbins which are wound on a spinning machine includes an attending device which is moveable along the spinning machine from one wound bobbin to another. A tending device includes a lever which carries a gripping mechanism, for swinging the gripping mechanism toward and away from a wound bobbin. The gripping mechanism has gripping arms which can be spread for receiving a wound bobbin and then brought together for grasping a wound bobbin. The gripping mechanism can then rotate the arms through 180.degree. and the lever can move the mechanism over a conveyor to deposit the wound bobbin onto the conveyor in the same orientation, whether the bobbin was removed from the spinning machine from one side or from an opposite side.
