Abstract

Abstract Translated from German Zur Herstellung von Verbindungen zwischen einem starren, dünnwandigen Formpreßteil und einem gummielastischen Randstreifen werden in einem Tauchkanten-Formwerkzeug zwei thermoplastische Ausgangsmaterialien (5, 6) eingebracht, zwischen den beiden Werkzeughälften (1, 2) plastifiziert und unter Druck- und Wärmeeinwirkung miteinander verschweißt. To produce connections between a rigid, thin-walled molded part and a rubber-elastic edge strip, two thermoplastic starting materials (5, 6) are introduced in a plunge edge molding tool, plasticized between the two tool halves (1, 2) and welded together under the influence of pressure and heat.
