Abstract

1375041 Moulding thermoplastic tufts on to supporting webs J DOLEMAN 21 Jan 1972 [13 Jan 1971] 1570/71 Heading B5A Thermoplastic material is fed into one or more mould cavities 7, the or each cavity then being brought into contact with, and the thermoplastic material bonded to, a web 10a permeable to the material. As described for forming matting, carpeting, turf, grass, a ski slope surface, or a soil retention medium, cylindrical cups of. petals are attached to a supporting nylon, metal or fibreglass web 10a, which is precoated with a thermoplastic. A heated 5 injection block 2 having a concave face, is held by hydraulic cylinders 8 in sealing engagement with a rotatable drum 20 having rows of mould cavities 7. Each cavity 7 includes an adjustable insert that determines the shape of the moulded body. Molten thermoplastic material from a reservoir 1 is injected at a rate controlled by trimming screws 4 into each row of mould cavities 7 in succession. The supporting web 10a is pressed into the cavities 7 by projections 12 on a roller 11 geared to rotate with the drum 20. Simultaneously, the web and thermoplastic material are bonded by a parabolic heater 13. The material is cooled by circulating water 9 in the drum and by a water-soaked sponge 14. At a station 16, the matting, etc. is removed from the drum 20, the petals spread and interlocked (by means not disclosed), and the matting wound on a roll 17. The drum 20 may be replaced by an endless conveyer supporting rows of mould cavities. The thermoplastic material comprises polyethylene, polypropylene, PVC, polyvinylidene chloride, polyvinyltetrafluoride, polyvinyl chlorotrifluoride, polyvinyl acetate, polyamides, segmented polyurethanes, polyurethane rubbers, silicone rubbers, natural and synthetic rubbers, or polyesters. Pigments and stabilizers may be added.
