Abstract
The described method serves for trimming or cutting during conveyance in a conveying direction (F) substantially in parallel to their main surfaces, flat objects along predetermined cutting lines parallel to the conveying direction (F). The objects are conveyed between a first and a second cutting edge (SK1 and SK2) and are cut by a relative movement of the two cutting edges. The first cutting edge (SK1) is positioned, e.g. stationary, in the plane of a support surface supporting the objects and for each cutting process, the second cutting edge (SK2) is moved past the first cutting edge in such a manner that at least the cutting point on the second cutting edge has a speed component in conveying direction (F) which has the same size as the conveying direction and a speed component perpendicular to the support surface. This is advantageously realized by a swiveling or rotating movement of the second cutting edge (SK2) around a rotation axis (M) arranged above the support surface, whereby for fulfilling the above condition, the distance (y) of the rotation axis from the support surface and the rotation speed (&ohgr;) are correspondingly matched. Advantageously, a plurality of second …
