A rotatable drum (10) useful in the manufacture tires. Plural segments collectively defining the outer circumferential surface of the drum are divided into two sets (18, 20) one set being disposed on each of the opposite sides of a transverse center plane (19). The two sets of segments are mounted for selective positioning thereof axially of the drum from a location external of the drum to adjust the overall working width of the drum. Movement of the plurality of segments of each of the two sets of segments radially of the rotational axis (14) of the drum is effected by "slaving" the two sets of segments off a central mechanism which controls the radial positions of all the segments simultaneously and equidistantly from the rotational axis (14), while further providing for axial movement of the two sets of segments relative to one another while the segments are positioned at any given radial location of the segments.

L'invention concerne un tambour (10) rotatif utile dans la fabrication de pneus. Les multiples segments définissant collectivement la surface périphérique extérieure du tambour sont divisés en deux ensembles (18, 20), l'un des ensembles étant placé sur chacun des côtés opposés d'un plan (19) central transversal du tambour. Les deux ensembles de segments sont montés en vue d'un positionnement sélectif de ceux-ci dans le sens axial du tambour, à partir d'un emplacement extérieur au tambour, afin de régler la largeur globale du tambour. Le déplacement de la pluralité de segments des deux ensembles radialement par rapport à l'axe (14) de rotation du tambour est mis en oeuvre par un <= asservissement >= décalé des deux ensembles de segments à un mécanisme central qui règle les positions radiales de tous les segments simultanément et de manière équidistante par rapport à l'axe (14) de rotation, ce qui permet d'assurer en outre le déplacement axial des deux ensembles de segments l'un par rapport à l'autre, quelle que soit la position radiale des segments.
