Abstract

838,219. Mandrels. JARAY, F. F. Oct. 19, 1956 [Oct. 26, 1955], No. 30558/55. Class 83 (3). [Also in Group XXVIII] A rotatable mandrel for making reinforced synthetic tubes comprises a tube 1 mounted on spiders 2 carried by shafts 3, and a tube 4 of rubber, silicone rubber or polyvinyl chloride clamped in fluid-tight manner at the ends thereof on to the tube 1. A pipe 6 for air or liquid under pressure communicates with the space between the two tubes to inflate the tube 4. In a modification, the tube 1 is perforated and closed at each end by discs, one of the spindles being hollow so that fluid can be passed into and out of the tube 1. According to the Provisional Specification, the tube 1 is of metal or wood.
