Abstract

A device for cutting the paper sleeve of defective filter cigarettes for recycling tobacco has at least one knife roller having a plurality of knife disks spaced from one another at a distance that is smaller than a diameter of the cigarettes. Each knife disk has a circumferential edge with a plurality of teeth. A conveyor belt feeds the cigarettes to the knife roller such that the cigarettes are essentially oriented parallel to the conveying direction. The conveyor belt and the knife roller are synchronized such that a circumferential velocity of the knife disks corresponds to the conveying velocity of the conveyor belt. As an alternative, the knife disks can be provided with a continuous circular dulled circumferential cutting surface. It is then necessary that the conveyor belt and the knife roller are synchronized such that a circumferential velocity of the knife disks is greater than the conveying velocity of the conveyor belt.
