Abstract

527,406. Moulding balls. MILNER, A. E. P., and SWIFT TENNIS BALL CO. PROPRIETARY, Ltd. April 11, 1939, No. 10997. [Class 87 (ii)] Apparatus for moulding hollow rubber balls, or like hollow articles, comprises a mould formed of separable sections 14, 15, a core 24 fixed on a support 23 the support and core being movable relative to the mould and so formed that air under pressure may be admitted to the interior of the ball to expand the ball for removal from the core. Compressed air may be passed after the mould has been opened, via the nipple 50 to the hollow centre of the support 23a in order to lift valve 30 and enter the interior of the ball 22 so that it is expanded and can be removed from the core. The valve face forms part of the moulding core. Specification 347,702 is referred to.
