Abstract
This invention relates to the preparation of a multi-layered rubber composite, said composite and a tire having a component prepared thereby. The multi-layered rubber composite is composed of at least two individual rubber compositions configured as at least three parallel aligned alternating rubber layers, wherein each rubber layer extends through the rubber composite thickness from one side to the other opposing side. The multi-layered rubber composite is prepared by co-extruding at least two individual rubber compositions, via an individual extruder for each rubber composition, to an internal cavity of a former. Said former is comprised of an internal cavity which contains a sequence of flow deflectors and channels for guiding the at least two individual rubber compositions to form said multi-layered rubber composite in a single manufacturing step.
