Abstract

A device for the cutting out of flat material blanks from flat material sheets is described, which has a cutting roller and a counter roller working together with it, that form a roller gap into which the flat material sheets can be inserted for the cutting out of flat material blanks, whereby a residual material is produced. This device should be further configured in such a way that on the one hand it is connected with the least possible device expenditure, and on the other hand is not limited in its application to flat material sheets with a specified minimum length. To solve this problem, it is suggested that both the cutting roller and the counter roller be embodied as suction rollers with a covering surface that has a multiplicity of suction air openings, whereby the suction air impingement on the cutting and counter roller occurs in such a way that immediately after the cutting out, the flat material blanks are able to be further transported on the covering surface of the cutting or counter roller and the residual material on the covering surface of the counter or cutting roller.
