[Class 120 (iii)] In cutting bundles of continuous artificial silk filaments into staple lengths continuously with their production from a spinning machine by leading the bundle through a radial passage 6 in a rotating wheel 3 and cutting the filaments by stationary knives 5 disposed at the peri. phery of the wheel, compressed air is forced through the passage in the direction of the entering bundle; the air reduces the friction of the bundle in the passage and so causes an increase in the centrifugal force acting on the bundle. As shown an air supply conduit 8 is cast in the wall of the funnel 7 leading to the passage 6 in the rotating wheel 3, and a supply tube 9 and an exchangeable nozzle 10 are connected to the conduit 8. Specification 289,028, [Class 120 (iii)], is referred to.
