Title: Vacuum-forming moulding process
Inventor: ROBERT SPRAUL JOSEPH
IPC: C08C19/30
Filed: 1969-08-01
Abstract: Vacuum-forming of heat-curable resinous mouldings is effected by fixing a web of elastomeric material over a vacuum-forming device with a heated mould.

Title: Folded seam helical tubing contuous prodn
Inventor: SIEGWART EMIL
IPC: B21C37/12
Filed: 1969-12-23
Abstract: Folded-seam helical tubing continuously Both edges of a continuous strip are truned up through a right angle, one a single thickness and the other a double thickness in the form of a flat 'U'. When the strip is wound helically on the mandrel, the single upturn fits inside the 'U' to form a continuous tube. The joint is folded down by an inclined roll that bears on the outside of the tube, and pressed into place by a second inclined roll at least 360 degrees down the mandrel. The rolls press the strip firmly on to the mandrel and the distance between the rolls allows the strip to adjust before the fold is pressed into place by the second roll. The flanges of the rolls are serrated circumferentially so that they grip the strip and move it along the mandrel, the end of which is slightly tapered.
