Abstract
During procedure such as a tire-recapping procedure, a strip of hot rubber mix of small width and thickness is applied by a collection block to a receiving surface of the tire as the tire is rotated relative to the collecting block. The hot rubber mix is supplied to the collecting block by an extrusion screw. The mix is advanced by the receiving surface through an extrusion orifice which forms the strip. A front surface of the collecting block converges toward an inlet of the extrusion orifice, causing the mix to be pressurized as a function of: the degree of convergence of the front wall and the speed of the receiving surface.
