Image Number 7 for United States Patent #5518037.
A pile forming apparatus allowing use of a driving motor of small capacity for effectuating terry motion while assuring high quality for manufactured pile fabric includes a ball screw constituting an output shaft of the driving motor with which driven nuts threadedly engage. One driven nut is operatively connected to a first arm of a displacement-direction change-over lever by a link. Displacement of the driven nuts caused by rotation of the ball screw is transmitted to an expansion bar via the link, the change-over lever, a first rod, an intermediate lever, a second rod and a supporting lever to displace the cloth fell of the pile woven fabric.
