Vorrichtung zum Herstellen von Kunststoffdichtungen als dichte Verbindung zwischen zwei Metallfolien sowie damit hergestellte Dichtungen

摘要

A plastic joint and apparatus for its manufacture which includes a first molding portion comprising a base supporting a body which can be displaced relative to said base, spring means biasing the body against the base and molding means being movable with respect to the base in response to displacement of the body, and a second molding portion comprising a base plate having a molding groove carrying a channel member of an electrically conductive material and induction heating means to heat the channel member to reduce a blank of a thermoplastic material contained therein, whereby the thermoplastic material is displaced between a gap between sheets of a rigid material to form a continuous closed joint body between the sheets of rigid material, the edges of the sheets being in molded engagement in continuous grooves in the joint body.
