ABSTRACT:
An automatic doffing device for ring spinning and/or twisting frames, in particular in machines for producing large packages, which comprises a conveyor arranged to convey the empty tubes into a vertical position corresponding with each of the spindles of the spinning and/or twisting frame, a second conveyor arranged to take away the full cops, and a gripper assembly arranged to effect the mutual transfer of the full cops and empty tubes between the conveyor supporters and the spindles.
The doubling of the conveyors and their location at the top of the spinning frame creel in a position overlying the spindles enables automatic doffing to be carried out on spinning and/or twisting frames without any regard for the size of the package (cop diameter and tube length).
