Abstract

973,431. Moulding inflatable balls. METTOY CO. Ltd. March 15, 1961 [March 15, 1960], No. 9080/60. Heading B5A. A hollow inflatable ball 10 is moulded by charging a mould 24, which has a protrusion 26 of material with a higher coefficient of thermal conductivity than the mould wall, with a predetermined quantity of heat-formable liquid plastic resin material, e.g. polyvinyl chloride plastisol, heating the mould and simultaneously heating the protrusion to form a thicker valve housing 12. The ball may be formed by slush moulding or by rotating the mould about a plurality of axes, then it is removed from the mould while still warm and pliable and a valve unit 14 is inserted through a passage 13. The protrusion 26 extends out through the mould wall 28 and is insulated from it by an asbestos plug 29. A thin copper disc shaped to provide parallel vanes 32 or a number of parallelly disposed discs may be attached to an outward extension of the protrusion to gather heat.
