Abstract
A suction pad for attracting a workpiece under vacuum has a cylindrical base to be connected to a vacuum source, and a skirt integrally joined to the base, for developing a vacuum therein to attract the workpiece. The suction pad can be kept at a temperature suitable for the workpiece, by an electric heater which is controlled in response to a temperature signal from a temperature sensor embedded in the skirt. The suction pad with the controlled temperature does not cause problems which would otherwise result from the different temperatures of the suction pad and the workpiece.
