Abstract
A clamping mechanism installed on a circulating conveyor is composed of a clamp and a supporting plate and a latch lever axially attached to the supporting plate. The clamp is designed to be opened to a specified extent by a coiled spring. When the clamp is closed against the operation of the coiled spring, it engages with a latch of a latch lever so as to be locked. A cloth sent out from the sewing machine advances between the opened clamp and the supporting plate. The clamp is closed by an air cylinder and clamps the cloth. When the latch lever engages with a limiting lever set at a specified position in the direction of movement of the conveyor, the lock is unlocked, and the clamp is opened to release the cloth.
