Abstract

In the blow-moulding process, a block, that has two or more layers of different synthetic material, is placed in the gap between two separate and opened formers. The upper part of the block is cut to form folds when the hollow sections of the former is closed and blown such that the folds are pressed together and are bedded into the block-body or the hollow former.
