发明名称 Method for closure heating
摘要 A method and appaatus for curing a gasket material on a cap, the apparatus having a microwave transmitter, associated wavegide and a device for moving multiple caps through the waveguide. A plastic material is applied to the cap so as to form a gasket. The cap is then moved through the waveguide where microwave energy is absorbed by plastic material. The plastic material then heats from room temperature to a predetermined curing temperature in the waveguide. The cap is then removed and allowed to cool back to room temperature so that the gasket material will harden.
