ABSTRACT:
A method and a device for the production of curved spring strip sections. A spring strip runs through a bending unit formed from three separate support points and a reverse bending unit, arranged in series, and formed from a fourth support point. Bent and reverse-bent spring strip sections are separated off from the spring strip in a separator unit. In order to achieve a compact construction for the device, the third support point of the bending unit and the fourth support point of the reverse bending unit are adjustable in position relative to the spring strip, by a controller with pre-set programs.
