Abstract
For the corrugated deformation of a flat sheet of material, an upper row (2) of shaping tools (4) is pressed against a lower row (3) of shaping tools (5). The shaping tools of both the rows are, with that, also simultaneously pushed together so that they trace the shortening of the sheet of material during the deformation. Thus, the situation is achieved where no relative displacement between the sheet of material and the facing sides (6, 6') of the shaping tools (4 and 5) takes place, also in the case of numerous corrugations of relatively great height. The lower row of shaping tools is arranged on a rotor, whilst the upper row is fixed at a working station within the area of rotation of the rotor.

A method for corrugated deformation of a flat material sheet (1) comprising steps of:
- providing a first row (2) of approximately prismatic, parallel shaping tools, and a second row (3) of approximately prismatic, parallel shaping tools adapted to intermesh with the tools of said first row, said second row of tools being parallel to said first row, and at least one of said rows being movable in a direction toward the other row to an intermeshed position,
- loading said sheet between said rows while said rows are in a non-intermeshed loading position,
- moving said second row of tools toward the first row to deform the sheet, while simultaneously, within each of said rows, closing the spacing between adjacent tools so that no relative movement takes place between the facing surfaces (6) of the shaping tools and the material sheet (1) during the deformation, and then
- moving one of said rows of tools and the deformed sheet therewith along a path to a depositing position, in which the material sheet is discharged.
A device for corrugated deformation of a flat material sheet (1), comprising
- a first row (2) of approximately prismatic, parallel shaping tools,
- a second row (3) of approximately prismatic, parallel shaping tools adapted to intermesh with the tools of said first row, said second row of tools being parallel to said first row,
- each of said tools in a respective row having a surface facing the other row,
- the tools within each row being movable with respect to one another to close their spacing so that no relative displacement takes place between the facing surfaces of the shaping tools and the material sheet (1) during the deformation,
- one of said rows of tools being movable in a direction toward the other row at a deformation station, and
- one of said rows of tools being movable, together with the material sheet, between different work stations.
