Abstract

L'invention concerne une préfilière de sortie (10) pour la fabrication de bandes de roulement pour pneumatique de véhicule, comprenant : • au moins un premier canal de circulation (13) configuré pour amener un premier matériau élastomère; • au moins un deuxième canal de circulation (14) configuré pour amener un deuxième matériau élastomère ; • au moins un orifice de sortie (16) vers lequel convergent lesdits premier et deuxième canaux de circulation (13, 14); • au moins un insert(19) amovible de préformage pouvant être facilement démonté, ledit insert(19) étant disposé dans sa position montée de manière à présenter au moins une partie d'extrémité (19') positionnée au niveau de l'orifice de sortie (16), à cheval entre lesdits premier et deuxième canaux de circulation (13, 14).The invention relates to an outlet pre-thread (10) for manufacturing vehicle tire treads, comprising: • at least one first circulation channel (13) configured to supply a first elastomeric material; • at least one second circulation channel (14) configured to supply a second elastomeric material; • at least one outlet (16) towards which converge said first and second circulation channels (13, 14); • at least one removable preforming insert (19) that can be easily removed, said insert (19) being arranged in its mounted position so as to have at least one end portion (19 ') positioned at the level of the orifice of outlet (16), straddling said first and second circulation channels (13, 14).
