Abstract (en)

[origin: EP2098381A2] The method involves re-guiding pressing rollers (1d), during a stamping process, under changing of an angular length or distance length of a rotation axis in reference to a transport route (2) and/or in reference to a tangential level of supporting rollers (1a) depending on variation of a design of chamfer surfaces of a work piece (3) to be punched. Outer surfaces of the pressing rollers are elastically deformed on a circumference of the surfaces depending of the variation of the design of the surfaces, where outer surfaces are loaded for the purpose of the re-guiding of a punching tape (1c). An independent claim is also included for a punching device for punching of a work piece i.e. panel, guided along the stationary transport route with the foil e.g. laminating foil or transfer foil i.e. hot punching foil.
