Abstract
A process for joining abutting thermoplastic synthetic resin foam structures by a strip which covers a junction zone formed between the foam structures including the steps of pressing a metal strip heated to above the softening point and or the melting temperature of the synthetic resin foam under slight pressure onto the junction zone and then allowing the metal strip to cool. In this manner, a bond is formed between the foam structures and the metal strip.
Claims11
A process for joining abutting thermoplastic synthetic resin foam structures having planar peripheral surfaces by a strip covering the junction zone between the foam structures which comprises heating a metal strip to above the softening temperature of the synthetic resin foam, pressing the heated metal strip under slight pressure onto the junction zone and allowing the metal strip to cool whereby a bond is formed between the foam structures and the metal strip.
