Abstract
1,108,122. Making tubes. ASSOCIATED TUBE COMPANIES (COMPOFLEX) Ltd. 6 Aug., 1965 [25 Aug., 1964], No. 34670/64. Heading F2P. In making a flexible tube a plurality of plies of strip material, such as polyethylene, polypropylene, polyvinyl chloride, fibreglass, neoprene, metal foil, rubber, glass cloth, silicone or polytetrafluoroethylene or any combination of these materials or textiles coated with plastics or elastomers, is fed around a fixed mandrel 1 and slidably rotated and axially progressed therealong by a band 3 rotated by pulleys and embracing the mandrel in a figure-of-eight at an angle with the material. The plies are laid simultaneously in overlapping relation and the number of plies so laid is determined by the ratio of the width of the ply material to the width of engagement of the band with the material. The tube may consist of two inner plies, two outer plies and an intermediate wire helix which may be pre-bent. A rubber roller 7, or rollers, bear on the tube to consolidate the structure and assist in sliding the tube along the mandrel. The strips forming the plies may be coated with an adhesive, to bind the layers of the strips together or alternatively ultrasonic, electronic and/or electric welding means, steam, hot air or infra-red heating may be used. A layer of polyurethane foam is applied to the tube by spraying or passing the tube through a frusto-conical device to meter the foam material on to the tube. Instead of a single band 3, there may be two driving bands, disposed one on either side of the mandrel, or contact rollers.
