INDUCTIVELY HEATED TOOLING AND METHOD FOR WORKING PLASTIC MEMBERS Abstract Of The Present Invention A plastic heating tool unit is provided for cutting, sealing and like working of a relatively thin or film-like plastic element. The tool unit may function to sever a plastic element from a web and create firm thermal attachment thereof to another member. The tool unit includes an appropriately shaped annular or circular tool element formed of appropriate material which is responsive to an inductive field for self-generation of heat within the material. An annular radio frequency induction coil unit is coupled to the tool element. A heat transfer member is secured to the tool element and to a forced cooled heat sink which cools the transfer member and thereby the tool element. The transfer member creates a selected retarded cooling rate of the tool element to provide an improved interaction of the tool member and the plastic element and for more effective heating and cooling thereof. The tool element is forced into operative engagement with the plastic element and by appropriate shaping of the tool element may force a plastic web toward a support and thermally sever the aligned annular portion from the web. The tool unit may be constructed to stretch a film-like plastic web, a foamed plastic web or the like during the thermal cutting thereof, and heat seal the severed plastic element to another member. The tool unit may also seal a preformed cover element to a container assembly in an automated assembly line apparatus having a separate sealing station with a fixed induction coil and a pressure clamp unit moving with the container assembly.
