Abstract:
An aspirator jet suction pick-up device for moving green sheets or other flexible materials employs a source of gas under positive pressure into the head with exhaust via a network of slots disposed along the pick-up surface of the head. As the gas exhausts through the ends of the slots via a manifold or plenum, an open groove on the pick-up surface entrains aspirated air causing a localized suction force. The suction force due to aspiration uniformly and stably holds a flexible sheet on the pick-up surface.
