摘要： For use with a sewing machine, a cloth pulling apparatus has a rotatable input shaft for coupling to a rotary drive force, and a pair of output shafts provided with cloth-pulling rotors mounted so as to feed cloth through a nip between the rotors. A variable transmission means converts the rotary movement of the input shaft to intermittent unidirectional opposite rotation of the cloth-pulling rotors. The transmission means comprises an eccentric rod pivotally mounted at one of its ends on the input shaft such that rotation of the input shaft effects oscillation of the other end of the rod. A one-way drive member is coupled to the output shafts such that oscillatory movement of the one-way drive member effects intermittent unidirectonal opposite rotation of the output shafts. A linkage effects oscillatory movement of the one-way drive member in accordance with oscillation of the oscillatory end of the eccentric rod, and this linkage is provided with adjustable means coupled to the eccentric rod for determining and varying the osicllatory path of the oscillatory end of the rod. Manually actuatable means are accessible from the exterior of the casing of the apparatus for adjusting the adjustable means so as to adjustably set the oscillatory path of the oscillatory end of the eccentric rod, and hence the oscillatory movement of the one-way drive member. The apparatus thus provides for precise control and variation of the movement of the cloth-pulling rotors from the exterior of the casing in a very simple and convenient manner.
