Abstract
An extrusion device for tires has a heatable extruder for extruding and supplying an elastomer to a prepared and rotatably supported carcass being rotated in a direction of rotation for entraining the extruded elastomer. The extruder has at least one die mouth facing a carcass sidewall. The mouth is a slot having a width and a length. The width extends in a direction of rotation of the carcass and is delimited by an upper and a lower edge. The length extends radially across the carcass sidewall. The slot has an outlet opening defining an area whose normal is slanted toward the carcass sidewall such that in the direction of rotation the upper edge of the slot is closer to the carcass sidewall than the lower edge of the slot.
