Abstract (en)

[origin: WO9605922A1] A sweeping member (5), together with a plate (2) which is to be worked and lies on a layer (4) of resilient material of a table leaf (3), is pressed over a certain distance, the depth of impression, into the resilient layer (4). Subsequently the sweeping member (5) is slid substantially parallel to the supporting leaf (3) over the plate (2) in the direction of the arrow P1, the resilient layer (4) being continuously impressed, thereby causing the plate material (2) to deform at the site of the zone of impression. By moving the sweeping member (5) continuously over the plate (2), that portion of the plate (2) which has already been swept will begin to display a curvature having a certain radius R. By varying the depth of impression, the plate material (2) can be provided locally with different radii of curvature.
