PROCESS FOR MANUFACTURING ELASTOMERIC TIRE COMPONENTS

摘要

A process for manufacturing an elastomeric tire component comprising the productive steps of a) preparing an elongated element including a cross-linkable elastomeric material by feeding it to an extruding device comprising a plurality of units each having a respective thermal inertia, b) delivering said elongated element onto a building support, and further comprising at least one non-productive step of c) submitting at least one of the units of the extruding device to a thermal transition, selected from heating or cooling, substantially reducing the risk of scorching during the thermal transition from and to the non-productive step ranking the units according to their thermal inertia and heating the units starting with the top-ranked unit sequentially to the bottom-ranked unit to reach the respective working temperature or cooling the units starting from the maximum working temperature unit sequentially to the minimum working temperature unit to reach the respective non-working temperature.
