Folding method for combining 2 sheets has edge of one sheet bent to angle of less than 90 degrees in direction of second sheet edge

摘要

The folding method uses a folding tool for bending the folded edge (2) of a first sheet (1) to provide an angle of less than 90 degrees, a second sheet (4) having a corresponding contour placed over the first sheet, so that its edge lies at a distance (5) of at least the sheet thickness from the inside corner of the folded edge of the latter. The folded edge of the first sheet is supported from the inside during the initial folding in the gap between the inside corner and the edge of the second sheet. An Independent claim for a folding device for combining 2 sheets is also included.
