Abstract

322,455. Macintosh & Co., Ltd., C., Young, H. C., and Hemm, C. April 29, 1929. Moulding hollow rubber balls.-In the manufacture of hollow rubber or ebonite goods from sheet stock by the use of two vented mould parts co-operating with a sealing-member having provision for the introduction of air under pressure, the exhaust of the air from the mould is restricted to create a cushioning effect and ensure even seating of the stock. As shown, the two mould parts 2 co-operating with a sealing-ring 3 having an air inlet 5, are finished with vents 7 communicating with chambers 9 fitted with spring loaded non-return valves 10 which impose a restriction and ensure even seating and, further, maintain a suction upon the stock during the separation of the mould parts for withdrawal of the ring 3.
