Pick-up head for moving a sheet of material.

摘要

An aspirator jet suction pick-up device for handling and 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 (32) disposed along the pick-up surface (12) of the head. As the gas exhausts through the ends of the slots via a manifold or plenum (22), an open groove (34) on the pick-up surface (12) 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 (12).
