An electrically driven fabric draw-off device (7) is disclosed which uses at least one electric motor (16) for driving at least one draw-off roller (13, 14, 15). The electric power is supplied via a rotary electrical interface which electrically connects the motor (16) on rotating frame (8) to the stationary electric supply (34). The rotational movement of frame (8) is caused by another electric motor (26) which is driven in response to a signal indicating the rotational movement of the cylinder (3) of knitting machine (1).
