ABSTRACT:
A die-base ring (11) has at its upstream end a tubular ring (12) provided with a collar (12a) and co-operating with means for fixing the ring to a support (1). The fixing device includes four radial screws (19), pressing against a cylindrical bearing surface (13) of the support and making possible a mechanically operated off-centering of the ring relative to the support, and a clamping collar (20) making it possible to place two cylindrical bearing surfaces (14 and 15) in strictly coaxial positions. Axial screws (16) pass through the support with sufficient radial play to allow the adjustment.
