Method of making moulds for studded tires

摘要

A method for producing a mould lining (G) intended for the manufacture of tires comprising tread blocks that have incisions in them and studs. A mould lining is produced by positioning lamella (L₁, L₂, L₃, L₄, L₅, L₆) of substantially equivalent shape and length on the parts of the lining (G) that are intended to mould the rubber blocks. In a next step, the material of the lining (G) and of the lamella (L₁, L₂, L₃, L₄, L₅, L₆) contained in a cylindrical space located at each of the sites intended to accept pins capable of moulding the housings for the studs is removed radially, and an insert supporting a pin is positioned in the hole obtained beforehand.
