Abstract
Apparatus and method for the manufacture of an annular uncured elastomeric component for a tire. The component (11) is formed on a disc-like mandrel (10) comprising a flexible support (12) having a frustoconical surface on which a strip of unvulcanized elastomeric material is wound to form the component, and a rigid carrier (13) on which the support (12) is mounted. The carrier (13) is adapted for mounting on a turning head (31) for rotation of the mandrel as the strip is laid onto said receiving surface. The flexible support (12) is used as a carrier to transfer the formed component to another tire building location.
Claims11
A mandrel for the manufacture of an annular uncured elastomeric component for a tire, said mandrel comprising a flexible support which is deformable in use,
- said flexible support having a generally radially outwardly facing frustoconical annular outer surface for receiving a strip of unvulcanized elastomeric material for forming an annular tire component thereon,
- said flexible support also having a generally radially inwardly facing frustoconical inner surface,
- said flexible support being mounted upon a rigid carrier positioned radially inwardly of the inner surface of said flexible support, said rigid carrier having an outer surface complementary to the inner surface of said flexible support,
- the carrier having attachment means for mounting on a turning head for rotation of said mandrel as a strip of uncured elastomeric material is laid onto the outer surface of said flexible support.
Apparatus for the manufacture of an annular uncured elastomeric component for a tire and which comprises:
- a means for producing unvulcanized elastomeric strip,
- an apparatus frame,
- a turning head mounted on the frame,
- drive means for rotating the turning head relative to the strip producing means,
- and, a mandrel detachably mounted on the turning head to receive the elastomeric strip, said mandrel comprising an annular flexible support having a frustoconical outer receiving surface thereon to receive said strip of unvulcanized elastomeric material, and an inner surface;
- a rigid carrier having an outer surface complementary thereto on which the inner surface of the flexible support is mounted, the carrier having attachment means for mounting the carrier on said turning head for rotation of the mandrel as said strip is laid onto said frustoconical receiving surface to form said component.
