Abstract: 483,833. Moulding flexible pipes. SUPERFLEXIT, Ltd., and GRINT, W. H. Oct. 30, 1936, No. 29595. [Class 87 (ii)] [Also in Group XXVIII] A flexible tube is produced by forcing a liquid medium upwardly into a tubular former so as progressively to contact with its inner wall and then allowing the liquid to recede under its own weight, the procedure being repeated so as to build up a tube layer by layer on the former which is finally removed. The former comprises a longitudinally split tube 1 which is held together by removable straps 5. The liquid medium in a tank 9 is forced by compressed air through the pipe 11 into the former 1 and is then allowed to recede by releasing the pressure. Hot air is then admitted through the pipe 14 to dry the deposited layer. The process is repeated until the desired thickness is produced. Sight glasses 13, 20 are provided to enable the flow to be controlled. A number of formers can be mounted in communication with the tank 9. To ensure adherence of the first layer the interior of the former may be coated with grease, mercury amalgam, &c. The liquid medium may comprise a solution of polyvinyl alcohol or of a waterproof synthetic resin. Solutions of natural or synthetic rubber or cellulose lacquers may also be used. Fillers, such as metal powder, asbestos, &c., may be added and the tube may be protected by a tape lapping, braided sheath of metal or textile threads, wire armouring, or a rubber covering.
