Abstract
771,906. Flexible tubes. COMPOFLEX CO.. Ltd. Feb. 7, 1956 [March 31, 1955], No. 9435/55. Addition to 743,693. Class 99(2) In the tube described in the parent Specification which comprises inner and outer helical coils and an intermediate body portion formed by an outer layer of synthetic rubber and an inner layer of material which is substantially non-extensible and impervous to gases, the inner layer is of "Terylene" or "Melinex" (Registered Trade Marks) film. Preferably, the film is applied over the inner coil in sheet form and by lapping, or in strip form by winding helically, the rubber layer being a preformed tube and applied over the film with the aid of compressed air. The coils may be of metal, but the outer coil may be of a synthetic plastic material or synthetic rubber.
