Abstract

A multiple lap-joint for sheets of thermoplastic laminates, the laminates having edges separated by high temperature removable film separators. The laminate sheets are heated under pressure and formed. The separators are then removed and the feathered edges of two adjoining sheets are interleaved and the sheets are reheated under pressure forming an integrally formed lap-joint.
