Abstract
The press forms tube, forming a sheet (11) over a mandrel (12), by rolling a pair of symmetrical rollers from a point on the mandrel over an arcuate surface to form the sheet. The rolling is performed by rollers (10) which are elongate to extend the length of the mandrel and biased one towards the other by springs (23) with sufficient force to form the sheet as they are rolled over the surface of the mandrel. The springs cooperate with each arm to produce a preset amount of force according to the position of an arm.
