Abstract
A cutting apparatus for ductile materials comprises a nozzle having a number of outlet openings separated from each other by separator webs. Next to the nozzle, a rotating cutting tool is provided, having a plurality of cutting knives for cutting off the strands of material discharged through the outlet openings of the nozzle. Each separator web is at least as wide as a cutting knife. For performing a cutting operation, the cutting tool is intermittently rotated. Between two cutting operations, the cutting tool is stopped, whereby its knives remain in a rest position behind the separator webs. For the next cutting operation, the cutting tool is rotated by such an amount that its cutting knives move from a position behind a first separator web to the next adjacent separator web.
