Abstract

A method for contour punching an output stack consisting of sheet-like material and a punching device for carrying out the method Includes providing at least two punching procedures. A large proportion of an unprinted region is separated from a printed region in a first punching procedure and a first punching waste produced thereby is collected separately, whereby the quantity of the second punching waste which is formed in a second punching procedure is significantly less than if only a single punching procedure were to be carried out. By collecting the first punching waste and the second punching waste separately, it is possible to provide this waste in each case for appropriate disposal or appropriate recycling.
