Tyre.

摘要

The tread pattern of a tyre is defined by an assembly of adjacent laminates (1) oriented transversally in the mould from one shoulder to the other and following ore next to the other circumferentially. Each laminate (1) consists of two pieces separated in their centre by a small distance (e) in the form of a leaf spring. The mould pattern is defined by charging depths of the laminates. The surface of the pattern between two successive radial laminates always being sensibly oriented perpendicular to the radial laminates. The distance between the laminate parts (e) is 0.1-5mm. Tyre tread moulding. Conserves advantage of rigid moulds and reduces sensitivity to changes in blank volumes. Simplifies mechanisms for opening and closing of moulds.
