<p>1,021,036. Coatings. GEORGE ANGUS & CO. Ltd. Jan. 1, 1965 [Feb. 4, 1964], No. 4684/64. Heading B2B. [Also in Division F2] A method of making a lined fire-hose comprises introducing into an open weave textile jacket 11, 12 a lining tube 13 of rubber or plastic, inflating the lining tube by internal fluid pressure, applying to the inflated hose a rubber or plastic material in paste or liquid form to penetrate the jacket 11, 12 and applying heat to bond the applied material to the lining tube 13. A second coating of plastic material is applied before heating to give the hose enhanced abrasion resistance. The jacket is of synthetic yarn and has continuous filament warps. The lining tube is extruded in a blend of P.V.C. and nitrile rubber and the externally applied material a P.V.C. paste. Alternatively the lining is of nylon or polyethylene terephthalate and the applied material a polyurethane adhesive. The two coats are applied from paste-boxes 16 and 17 which have rubber diaphragms at their ends and the box 18 houses infra-red heaters 20. The three boxes are mounted on a wheeled trolley, Fig. I (not shown) which is traversed along an inflated length of the hose which is suitably supported at its ends.</p> |
