Abstract

A vacuum cup is described comprising a body portion having an elongate cavity and a contact surface for contacting a glass sheet to form a chamber with the elongate cavity and the glass sheet. An opening in the body portion is in fluid communication with the elongate cavity for connection to a low-pressure source so that the contact surface can form a seal with the glass sheet to attach the vacuum cup to the glass sheet. The periphery of the elongate cavity has major and minor axes orthogonal to one another, the major axis being longer than the minor axis. The periphery of the elongate cavity has first and second end portions at respective ends of the major axis, the first end portion being larger than the second end portion. Methods of using such vacuum cups to support a glass sheet during processing are also described.
