A method of forming a tire component (10) from an unvulcanized elastomeric strip having two or more laterally adjacent distinct compounds is provided. The method includes the step of feeding a first compound into a pair of calender rollers (350, 352), wherein one of the rollers (350) has a forming depression (356). The first compound is formed in a first portion of the forming depression (356). Next, a second compound is fed into the pair of calender rollers (350, 352). The second compound is formed in a second portion of the forming depression (356). The second compound is laterally separated from the first compound by one or more separating means (320) for separating the first and second compounds.

Cette invention concerne un procédé de mise en forme d'un composant (10) pour pneumatique à partir d'une bande élastomère non vulcanisée qui comprend deux composés distincts et latéralement adjacents, ou plus. Ce procédé consiste à envoyer un premier composé dans deux cylindres de calandre (350, 352), l'un des cylindres (350) comportant une dépression de mise en forme (356). Le premier composé est mis en forme dans une première partie de la dépression de mise en forme (356). Un second composé est ensuite envoyé vers les cylindres de calandre (350, 352), puis mis en forme dans une seconde partie de la dépression de mise en forme (356). Le second composé est ensuite séparé latéralement du premier à l'aide d'un ou de plusieurs systèmes de séparation (320) desdits composés.
