Abstract
A method and a device for bending and reshaping profiles by means of roller bending or matrix bending. The profile that is to be worked on is bent or reshaped under the influence of one or several bending tools. In order to be able to bend and reshape also brittle profiles that are difficult to bend, an oscillator whose oscillations are supplied to the profile that is to be bent or reshaped, at least in the reshaping zone, is assigned to at least one of the bending or reshaping tools, or both.

1-14. (canceled)
A method to bend and reshape profiles through roll or matrix bending, wherein the profile is bent or reshaped under the influence of at least one bending or reshaping tool, the method comprising:
- providing oscillations for said at least one bending or reshaping tool, or both;
- applying the oscillations of the at least one bending or reshaping tool, or both, to the profile to be bent or reshaped in at least the reshaping zone;
- and
- subjecting the profile to be bent or reshaped to a flow process whereby the outside of the material of the profile to be reshaped is stretched and the profile is compressed on the opposite area, the profile being subjected to the oscillations during the flow process.
