Abstract: Method for producing sheets of corrugated cardboard with a variable format in which a web of corrugated cardboard is removed continuously from a heating and pulling device of s conventional corrugated cardboard installation. The sheets are processed to the required format in at least one longitudinal cutting and grooving device. For this purpose the web is conveyed through a pulling device. A cross cutter cuts the sheets of corrugated cardboard from the cardboard web according to a preset format. The cardboard web is conveyed to a cross cutter for the corrugated cardboard sheets in the direction of conveyance without cutting them crosswise. When the format is changed, the area of the web of corrugated cardboard where the formats overlap is cut out by the cross cutter and removed to a waste container through a trap.

Abstract: Upon upper and lower cutting tools, in a slitting machine, cutting along the opposite edges of a web being adjusted transversely to the web, a corresponding suction nozzle, for taking up the cut-off edge of the web, is correspondingly adjusted transversely to ensure that it takes up the cut-off edge, by a respective drive unit. For ensuring entry of the leading end of a cut-off edge strip into the nozzle, a respective finger is swung down in advance of the leading end.
