Abstract

1443420 Moulding inflatable rubber tubes DUNLOP Ltd 10 Aug 1973 [18 Aug 1972] 38542/72 Addition to 1367084 Heading B5A An improvement in or modification of the invention in Specification No. 1,367,084 comprises moulding an annular inflatable rubber tube in a cavity having a cross-sectional width less than and a depth greater than that of a cavity of semicircular cross-section having the same cross-sectional peripheral length. It is therefore possible to mould three inner tubes 6, 7 and 8 in the same machine. The mould cavity can be W-shaped in cross-section, and it can be non-circular in plan, Figs. 6 and 7 (not shown).
