Abstract
The coextrusion installation is intended to generate a profiled element for a tire tread by extruding a sublayer made of first elastomeric compound, an overlayer made of second elastomeric compound for forming the tread pattern blocks, and inserts made of third elastomeric compound. The installation includes pre-scrapers followed by scrapers for deepening the embedding trenches, injectors for injecting an insert at the bottom of each embedding trench, and then a covering wall which allows the streams of the second elastomeric compound to meet by filling the embedding trench in question and by covering the corresponding insert so as to embed the insert at a predetermined embedding depth.
