ABSTRACT:
In a bending machine for wire or strip materials comprising a machine body (1) defining a work face (2) and having disposed thereon at least one planar and undercut guide path (F1 to F3) for tool mounting carriages (S1 to S4) mounted thereon for displacement therealong at least between operating positions by means of a selectively remote-controlled displacement drive system (7) and for being locked on said guide path in the selected operating position, each tool mounting carriage (S1 to S4) defining an operating axis (A1 to A4) extending substantially perpendicular to the respective guide path, and being provided with a tool carrier (6) mounted for displacement along the operating axis (A1 to A4) by means of an operating actuator (5), at least one guide path (F1, F2, F3) is formed with an arcuate curvature in the guide plane, the curvature preferably following a circular arc (K), and the concave side of the curvature facing towards a material feed axis (3).
