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.
Claims7
A fabric workpiece transport mechanism comprising a pair of spaced apart wheels, a continuous drive belt of resilient material entrained about the wheels, switch actuated motor means for intermittently driving the wheels and the belt, at least one unitary gripper finger permanently attached 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 sensor switch means for detecting the presence of a fabric workpiece edge between the gripper finger and the belt and for then energizing the motor means.
