Abstract (en)
[origin: EP0491658A1] To deform a sheet material into a wave form, a fixed row (2) of form tools (4) is pressed against a movable row (3) of form tools (5). The form tools of the two rows are in addition simultaneously pushed together, thus reflecting the shortening of the material during the deformation. This ensures that no relative displacement between the material and the end faces (6, 6') of the form tools (4 and 5) takes place even if there are a plurality of shafts with a relatively great height. The movable row of form tools is arranged on a rotor while the fixed row is secured at a work station in the range of rotation of the rotor. <IMAGE>
