Abstract

The mechanism (4a) is intended for forming a conical tube from a seamless cylindrical tube (16) by passing it between two stretch-forming rollers (14,14a) each having a perimeter groove (15,15a) with circumferentially reducing cross-section. A main frame (1a; 1,1) has two parallel guides (2,2a) for two transverse yokes (5) connected to hydraulic actuators (6,9), of which the piston rods (7,9') have their ends secured (8,10) to a transverse frame member and to a carrier (4). This carrier is similarly slidable on the guides and contains the rollers, of which the shafts (11,11a) are coupled via meshing gears (12,12a). One shaft (11) is driven, via a gear train (13,13a) meshing with a fixed tooth rack (3) in the frame. The end of the tube (16) is secured to the transverse frame member.
