Abstract

1486781 Moulding tyres UNIROYAL 26 Sept 1974 [5 Oct 1973 28 Feb 1974] 41899/74 Heading B5A A raw tyre carcass to be shaped and vulcanized in a mould includes an uncured airimpervious liner 1 of thermoplastic material attached to the inner surface of the carcass and extending from bead to bead; parallel ribs 2 on the inner surface of the liner extend obliquely from bead to bead and provide passageways for the venting of fluid from between the liner and an inflatable bladder during the curing in the mould, the ribs being flattened by the smooth outer surface of the bladder to provide the liner with a smooth interior surface. The uncured liner may be thicker at the midcircumferential plane of the carcass to provide a cured liner of substantially uniform thickness. Such a liner may be produced by a pair of rolls, one smooth and the other having appropriately formed grooves in its periphery.
