Patent ID: 7749417

Claim:
A method for producing small, thin sheets from an active-ingredient film, in which the latter is produced by casting the film material onto a substrate material or by coating a substrate material, comprising the following steps: storing the film with or without the substrate material on a reel; pulling the film off the reel; separating the substrate material, if present, from the film; feeding the film in tensioned form to a cutting station; cutting the film in the feed direction, into long, narrow strips of predeterminable width; bringing the long strips together in the feed direction; arranging the long strips on top of one another in the form of a stack of individual strips; feeding the stack of individual strips by a further feed device to a transverse cutter in that the stack of individual strips is pulled over a slideway by the further feed device and the stack is smoothed in this step, said slideway being three-sided and U-shaped in cross section, and being bent convexly around an axis which lies transversely with respect to the feed direction so as to produce prestress in the stack, with the width between the side walls of the three-sided slideway substantially corresponding to the width of the stack, wherein the feeding of the stack of individual strips to the transverse cutter causes the stack of strips to slide between a pair of guide jaws, one guide jaw of said pair of guide jaws being arranged above said stack of individual strips, and the respective other guide jaw of said pair of guide jaws being arranged below said stack of individual strips; and cutting through the stack of individual strips at predetermined intervals with the transverse cutter.
