摘要： There are described an improved vacuum suction pad and a method for manufacturing such suction pads, in which, in addition to reductions of contaminant components, the material of vacuum suction pads is subjected to an improved surface treatment which prevents deposition of pad marks on work surfaces and reduces frictional resistance of suction pads on work surfaces to lessen their fatigue. Suction pads of synthetic rubber, to be connected to a vacuum source, are each formed with a thin halogenation-hardened layer at least on a sucking surfaces to be held in contact with a work surface.

摘要： 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.
