ABSTRACT:
In a textile winding machine each of a pair of arms is connected at one end to a first wheel and supports a bobbin at the other end in a winding position with the bobbin resting against a driving roller. An endless band, such as a chain, extends around and engages both the first wheel and a second wheel and also passes around a tension roller. The second wheel is connected to a motor for being selectively driven in each of two directions and for driving the first wheel via the endless band. When not driving the second wheel, the motor blocks rotation of the wheels. The tension roller is positioned by the action of tension control means which has an active and an inactive position. The tension control means includes a shoe abutting against a bladder adapted to be connected selectively to a source of compressed air and to a discharge. In the inactive position, when rotation of the second wheel is blocked, winding of the bobbin can proceed and the bobbin can be lifted manually from the driving roller, however, when the tension control means is in the active position the tension roller is displaced against the endless band so that driving of the second wheel in one direction serves to drive the first wheel and raise the bobbin from the driving roller for ejection and replacement with a fresh empty bobbin, and driving in the other direction brings the fresh bobbin into the winding position resting against the driving roller.
