摘要

An extrusion head comprising a feeding device (12) formed by at least a feeding module (14, 15, 16) and a shaping device (13). Each feeding module comprises one or several supply channels (21) of material to be extruded. The channels have a tangential material intake. The shaping device comprises at least a pair of forming rolls (22) and a support (23). The rollers are mounted so as to pivot about a central pin (24) perpendicular to the longitudinal axis (25) extruding direction. During extrusion, the support (23) and the rolls (22) rotate so as to shape the extruded cable.
