Abstract
The invention relates to a machine and method for the semi-continuous cold-bending of sections (3) with low ductility, of the type including a horizontal mount (1) and an interchangeable tool (4) against which the section (3) is bent. The machine includes a gantry support (10). The tool (4) is located in a zone delimited by the mount (1), vertical supports (5) for the tool (4), and a compression plate (7) actuated by vertical pressure cylinders. The tool (4) is positioned facing an actuation plane defined by a double set of hydraulic positioning (23) and push (20) cylinders. The bent sections (3) can be used for tents, skylights, facades, solar shading louvres, or three-rail frames for truck tarps, guaranteeing a uniform bend in all bent sections, without the section becoming pinned in the machine during bending.
