Abstract
A continuous process for producing honeycomb support structures by bonding a plurality of thermoplastic sheets together. The process comprises feeding, aligning, supporting and bonding thermoplastic corrugated sheets in sequence to build a honeycomb-structure of the desired dimensions. Bonding is accomplished by impulse heating through retractable support bars in cooperation with a movable heating/cooling platen, pairs of sheets to be bonded being indexed therebetween, in sequence, to bond one sheet at a time to form the multi-sheet structure.
