Abstract

1305017 Cricket or hockey ball TONBRIDGE SPORTS INDUSTRIES Ltd 29 April 1970 [5 May 1969] 22907/69 Heading A6D A ball is made by binding a moulded spherical resilient core portion with cord which is not rendered extensible by heat, heating the bound core and moulding an outer casing from a resilient plastics material about the bound core whilst the bound core is still hot. In the figure, core 10 made of cork granules coated with rubber is bound with cord 11 which is made of worsted and is in a wet condition and under tension. The bound core is then heated to between 100‹F and 200‹F and has an outer casing 12 of polyvinyl chloride approximately 1/4" thick moulded about it while the bound core is still hot.
