An extrusion head (12) is mounted on a support (11) borne by a movable assembly (8). By rotation of two arms (9 and 10) about their pivoting axes on a base (6), the extrusion head is moved from a preparation position to a working position. Beforehand, another extrusion head (14) which had been in working position was removed after opening of a clamp (21) and maneuvering of another movable assembly (18) so as to reach the preparation position, where new tooling can be put in place, adjusted, and regulated, and where the extrusion head can be preheated.
