Abstract
A machine for bending tubes (1) with small diameters, which are pre-cut and provided with connection systems at both ends. This machine comprises elements (5) for grasping the rear end of the tube (1), elements for entrainment of the grasping elements according to a longitudinal axis, and at least one bending head, comprising two forming rollers (7, 8), each of which has at least one peripheral groove, a folding finger (23), which is associated with a unit (24) for displacement according to a circular path which is centered on an axis (Y) at right-angles to the axis (X), and with a system (29) for displacement in translation according to an axis (Y.sub.1) which is parallel to (Y), and guide units for the tube (1), which are disposed upstream and in the vicinity of the forming rollers (7, 8).
