摘要： A device for continuous chipless separation of single identical rings from a tubular workpiece, includes at least two cutting rollers which are placed about the tubular workpiece, and which operate in a same direction and are interconnected by a positive engagement. Each cutting roller includes a basic body having opposite axial ends defining an entry zone and an exit zone, respectively. The basic body has a slip bevel at the entry zone, a calibrating section at the exit zone, and a cutting screw disposed between the slip bevel and the calibrating section and including a helical main thread portion with a conical entry part and a substantially cylindrical primary part in succession of the entry part, whereby the cutting screw has at least one additional thread which is disposed between threads of the main thread portion of the cutting screw.
