Abstract

A process in the blow moulding or vacuum forming of a flexible thermoplastic tube which is curved in at least one plane, the tube blank (preform, parison) being grasped, immediately it emerges from an extruder, locally by movable vacuum drawers which are moved while carrying the tubular blank (preform) along with them so that the latter assumes the desired form before the preform is introduced into a cavity for further processing. A device for carrying out the process is also specified.
