Abstract 893,034. Stapling fibres. GOODYEAR AIRCRAFT CORPORATION. June 27, 1960 [July 8, 1959], No. 22385/60. Class 120(3) Glass fibre and like continuous filaments are cut into short lengths by at least one blade carried by one roll of a pair of cutter rolls between which the filaments pass. Tubular suction means remove the cut fibres at a higher speed than that at which filaments are pulled through the rolls and also separate the fibres. In the apparatus shown, tows or bundles of filaments 10 from bobbins 11 are fed through guides 12 and 13 to the nip between adjustably mounted cutter rolls 2 and 3. Cut fibres 30 are sucked into a throat 14 in a head 15 connected by a flexible conduit 16 to a nozzle discharge head 17 of a spraying apparatus which includes air pressure conduits 18 controlled by valves 19 which create a vacuum in the throat 14. Rolls 2 and 3 are formed of rigid material covered with sleeves 21, 22, of reislient material. The sleeve 22 is tougher and stiffer than sleeve 21 and deforms it when pressed thereagainst so as to grip resiliently the filaments as they are severed by one of several radial blades 25 received in grooves 26 in roll 2 and rockably secured by flexible wires 27. The blades of circumferential rows on the roll 2 are staggered, Fig. 2 (not shown) so that cut fibres from each of parallel filaments are supplied alternately.
