Abstract

The feed mechanism and the pipe bending head (2) are ariven from one source. The feed has two parallel sets of rollers (17) symmetrical along the axis of the pipe (14). The rollers are held in cages (19, 20), one of which can turn normal to the roller axis and is spring loaded toward the other cage. Two closed loop hauling chains (28) enclose the rollers of each row and are linked to the drive to displace the work toward the bending head. Two closed loop strips are of resilient material (29) and are fitted to the outside of each chain. The pipe is then clamped in the gap between the material faces. Each chain pref. comprises the individual gear racks with teeth facing the rollers and driven by a gear pinion.
