Abstract: A method for making rubber portions comprising tyre metallic reinforcing plies. This method comprises an incorporation step wherein metallic cords which constitute the plies are arranged between two skim layers and a treatment step for the metallic cords, that precedes the incorporation step and wherein the metallic cords are wetted with a diene elastomeric polymer with a viscosity of between 3 and 10 Pa·s at room temperature.

Abstract: A belt for tyres comprising a ply made up of metal cords and two layers of tread ply skim arranged to cover the ply. The ply is coated with a protective composition comprising at least one cross-linkable unsaturated-chain polymer base and a surface-active compound. The protective composition is derived from an aqueous-based suspension applied to said ply. The tread ply skim comprises the same cross-linkable unsaturated-chain polymer base present within the protective composition.

Abstract: A method to produce a compound for a tyre sealant layer, comprising a swelling step, during which a crumb rubber is immersed in a process oil chosen among the ones belonging to the families of paraffin process oils, naphthene process oils or natural process oils, so as to obtain a crumb rubber that swells due to the absorption of the process oil; and a following mixing step, during which said swollen crumb rubber is mixed with at least one polymer base consisting of an essentially saturated polymer.
