ABSTRACT:
A device for driving a thread take-up lever in a multi-head sewing machine having a plurality of sewing heads, one or more thread take-up levers each mounted on a respective head, and a main shaft for driving the heads. The device comprises a movement converting mechanism located within each head for converting rotational movement of the main shaft into reciprocating movement thereof, a transmission control mechanism operatively associated with the movement converting mechanism for transmitting and disconnecting the reciprocating movement produced by the movement converting mechanism to one of the thread take-up levers selected for sewing operation, and a retaining mechanism for retaining the selected take-up lever in a predetermined position when the reciprocating movement of the movement converting mechanism is disconnected from the selected take-up lever by the transmission control mechanism.
