ABSTRACT:
An improved lifting device for a vacuum transfer system has an elastomeric gasket that provides a contact area which has a large cross-sectional area and is more stable and longer lasting than prior art devices. The elastomeric gasket is typically retained in a housing where vacuum can be supplied to the inside thereof. The Elastomeric gasket, providing a contact surface that is flexible yet strong and having a larger contact area than the lip of a typical suction cup, provides an improved seal between the pick-up device and the article to be moved and a longer period of time before the contact surface needs to be replaced.
