method and device for ausstanzen randoffener excerpts in heftrand of faltbogen

摘要

The method involves using punching tools to make cutouts in drawing sheet edges between longitudinal and cross foldings. Open-edged cutouts (32) are made in the side edges (42) of drawing sheets, which coincide with punched holes (46) after folding. The cutouts are made mechanically, between longitudinal and cross folds of the drawings (11). The cutter device has at least two punching tools, located on the cross fold table of a folding machine. Transporters move the drawings towards the punches in a first direction of movement, at right angles to the longitudinal direction of the filing edge.
