Abstract
The machine includes an extrusion head having flow ducts, the inlet orifices of which are connected to the outlets of at least two extruders for supplying extruded strips made of elastomeric compounds. The outlet orifices lead into a die which is adjacent to a roller and is designed to cooperate with the latter to shape the profiled element strip. The roller has a central axis surrounded by an external surface intended to receive the profiled element strip and a means for driving the roller in rotation about its central axis. The flow ducts are mutually parallel and are perpendicular to the circumferential direction of the roller, and the profiled element strip is joined to the receiving surface of the roller along an equivalent length of at least 700 mm.
