Abstract:
A method for separating a profiled foil comprising rotating a planar, circular separating foil in a rotational plane, holding the profiled foil at a cutting location, moving the rotating separating foil relative to the profiled foil so that a peripheral portion of the separating foil forms a cut through the profiled foil, forming a stabilization gap between opposing stationary walls at the cutting location in substantial alignment with the separating foil, arranging the walls to provide a spacing between the walls which is 0.1 to 0.5 mm greater than a thickness of the separating foil, and stabilizing the rotating separating foil by moving a segment of the rotating separating foil through the stabilization gap so that air pressure forms on each side of the separating foil segment disposed in the stabilization gap and centers the foil in the gap to prevent contact between the rotating separating foil and the walls.
