PROCESS AND DEVICE FOR BUILDING A GREEN PNEUMATIC TIRE BY MEANS OF A STRIP

摘要

In the method for manufacturing an uncured blank of a vehicle tire, a strip (30) of rubber is extruded and is made to pass between two members (18, 10) one of which forms a roller (18) for extruding the strip, such that the faces (21, 23) of the strip, forming one and the same section of the strip in a plane perpendicular to a direction of travel of the strip and pressing simultaneously against the respective members, are driven at linear speeds that differ from one another, and that the members (18, 10) stretch the strip between them.
