1. Technical Field
The invention relates to a device and a method for flanging, preferably roll-flanging, a component part. The device and the method preferably serve for hemming, particularly preferably roll-hemming. The invention can in particular be used in the construction of vehicles, preferably the construction of motor vehicles. Body parts, for example a door, a wheel arch or other part of an outer side wall, the front or rear of a motor vehicle, may in particular be considered as component parts to be reshaped.
2. Description of the Related Art
A roll-hemming device is known from WO 03/024641 A1, comprising three hemming, rollers which are used consecutively in a plurality of processing runs and, for this purpose, can optionally be moved into a processing position in which they roll off on a hemming web and bead the hemming web. In order to completely bead the hemming web around a hemming edge, the known device requires three processing runs, between which the next hemming roller in each case has to be moved into its processing position.
It is therefore an object of the invention to reduce the time and therefore cost of flanging, required for multiple-stage flanging, preferably roll-flanging.
