  • Publication number: 20040076799
    Abstract: The invention relates to a method and a device for producing small, thin sheets from an active-ingredient film (2), in which the latter is produced by casting the film material onto a substrate material or by coating a substrate material, storing it with or without substrate material on a reel, pulling it off the reel and cutting it. It achieves the object of designing a method of this type in such a way that with this method small sheets can be produced as exactly as possible in predetermined sizes. To do this, the active-ingredient film (2) is pulled off automatically, is separated from a substrate material which is present and, in tensioned form, is fed to a cutting station and is cut, in the feed direction, into long, narrow strips (7) of predeterminable width, and the long strips (7) are brought together in the feed direction and together are fed by a further feed device (10) to a transverse cutter (11), which cuts through the combined long strips (7) at predetermined intervals.
