Abstract

A fabric workpiece removal mechanism which includes a pair of spaced apart pulley wheels, a continuous drive belt of resilient material entrained about the wheels, a switch actuated motor for intermittently driving the wheels and the belt, at least one gripper finger clamped to the belt for clasping the edge of a fabric workpiece against the belt, the gripper finger being bent inwardly toward the belt to deform the belt from its natural configuration and a sensor switch for detecting the presence of the fabric workpiece edge between the gripper finger and the belt and for then energizing the belt drive motor.
