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.

Abstract: A method and device for producing a tear line on a planar workpiece by material removal by means of a pulsed laser, wherein machining cycles are preceded by a method step for generating and storing a reference signal curve which is formed by reference signals, causing the pulse amplitude of the laser pulses, via removal locations along the contour of the tear line. The achievement of a respective predetermined percentage of the reference signal or of an absolute distance from the reference signal by a measurement signal is used as the space-resolved deactivation criterion for each removal location, which measurement signal is obtained from a transmitted part of the pulse amplitude at the respective removal location.
