Title
(EN) METHOD OF APPLYING A TYRE TREAD ON A CARCASS
(FR) PROCEDE PERMETTANT D'APPLIQUER UNE BANDE DE ROULEMENT DE PNEU SUR UNE CARCASSE
Abstract
(EN)
The invention relates to a method of applying a tread (3) to a tyre casing (1) wherein a prevulcanised tread (3) is applied to the tyre casing (1) via an intermediate layer of non-vulcanised rubber binder (2), and wherein the layer of rubber binder (2) is heated by supplying current to said layer through an electrically conductive wire (4). The wire used in accordance with the invention comprises a multiple of wires or strands (4a). The invention also relates specifically to such a multiwire element.
(FR)
L'invention concerne un procédé qui permet d'appliquer une bande de roulement (3) sur une carcasse (1) de pneu. Selon le procédé, on applique une bande de roulement prévulcanisée (3) sur la carcasse (1) au moyen d'une couche intermédiaire d'adhésif caoutchouteux non vulcanisé (2), puis on chauffe ladite couche d'adhésif caoutchouteux (2) en amenant du courant sur ladite couche par un fil électriquement conducteur (4). Le fil utilisé dans le procédé de l'invention est constitué d'une pluralité de fils ou de brins (4a). L'invention concerne également ledit élément multifilaire.
