Abstract

1,182,750. Winding mandrel. FARBENFABRIKEN BAYER A.G. 13 Feb., 1968 [24 Feb., 1967], No. 7083/68. Heading F2P. A winding mandrel 1 for the production of tubes of glass-fibre reinforced duroplasts consists of an inner jacket 2, made e.g. of steel and which is provided, at its ends, with inlets and outlets for a heat-regulating medium, an outer jacket of thermoplastic synthetic resin 3, which has, in comparison with the material of the glass-fibre tube wound thereon, a higher coefficient of thermal expansion, being shrunk on to the inner jacket 2. The mandrel 1, preferably with an outer jacket made of polytetrafluorethylene, is hollow to receive a heating or cooling medium, e.g. steam or water, and is mounted upon bearings 6 for rotation by a motor 8 by way of belt pulleys 9, 10. The cavity of the mandrel is sealed off by packing gland connections 5. A tube of glass-fibre reinforced duroplast is formed by heating the mandrel 1, glass fibre material, e.g. in the form of rovings, mats, or webs, saturated with unhardened duroplasts, e.g. a polyester or epoxide resin, being wound on to the mandrel 1 and the latter being cooled after the duroplast has hardened when the tube can be easily removed.
