<p>789,353. Making cemented pile fabrics; stapling fibres. ETABLISSEMENTS GIROUD FRERES, LES SUCCESSEURS DE HUGUES GIROUD & CIE. Feb. 20, 1956 [Feb. 22, 1956], No. 5111/56. Classes 120(3) and 142(4) A machine for making pile fabric by spraying latex on to a layer of cut fibres or by securing a backing on the layer comprises means for cutting successive strips of fibres from a layer of parallel fibres and engaging the cut portions in a guide. The layer of parallel fibres may be several superimposed carded webs. The cut portions are fed by moving bands to the device for spraying adhesive or to the backing. The cutting means comprises a circular cutter 12 rotated by a cable 17 passing round a pulley 16 as the cutter traverses, and a fixed blade 5a beneath which the circular cutter engages. With this arrangement, the cutter 12 moves the fibres into the guide as they are cut. The cutter is mounted on a carriage 14 traversed along bars 15 by crank and link mechanism. The fibres 1 are fed between plates 2, 3 by a pair of wheels, one of which is ratchet operated, and are supported adjacent the cutters by a resilient arm 7 and a plate 9, the latter having arms 10 carrying a rod 11 engaging a groove 12a in the cutter. The plate 9 is pressed against and removed from the fibres by cam and link mechanism. The fibres passing from the guide 4, 5 are fed between bands 28, 29, the band 29 being further from the band 28 at the exit end than at the entry end. Further bands 37, 38 having a lower speed than bands 28, 29 are provided so as to compress the fibres. Finally, the cut fibres are carried on a band 47 beneath the spraying device 48 or to the backing.</p> |
