Abstract (en)
[origin: FR2738170A1] A movable head (3) includes spreader shafts (27), guide carriages (4), a fixed end block (5) and a drive (6-8). A cylinder (10) of polygonal cross-section is attached to the head, with at least some of its faces having attachment points of different configurations for the rear ends of the spreader shafts. The attachment points are formed by perforations, e.g. of keyhole shape, in the cylinder surface which cooperate with a mobile plate with similar perforations. The rear ends of the spreader shafts include a narrowed portion close to the ends, defining an end head which engages in the keyhole-shaped perforations for selective fastening.
