Abstract
Tambour de confection (10) expansible radialement destiné à la fabrication d’une ébauche d’adaptateur (1) de pneumatique sur une jante, d’arbre central d’axe X-X’ pour une zone de confection (50) munie d’une pluralité de segments (100, 200), lesdits segments comportant des gorges (103, 203) de réception de tringles, et comportant des dispositifs de retroussage (30, 40) autour de tringles disposés de part et d’autre de la zone de confection (50) en étant adaptés pour être déplacés axialement l’un vers l’autre et l’un à l’écart de l’autre, chaque dispositif de retroussage comportant plusieurs bras de retroussage (31, 41) adjacents disposés circonférentiellement sur le tambour où chaque bras de retroussage présente une extrémité proximale (32, 42) apte à retourner les composants autour des tringles, caractérisé en ce que l’extrémité proximale (32) de chaque bras d’au moins l’un des dispositifs de retroussage (30) comprend au moins deux ressorts hélicoïdaux toriques (321, 322) adjacents, chacun étant destiné à venir au contact de l’ébauche. Figure pour l’abrégé : Fig. 1Radially expandable building drum (10) intended for the manufacture of a tire adapter blank (1) on a rim, with a central shaft of axis X-X' for a building zone (50) provided with a plurality of segments (100, 200), said segments comprising grooves (103, 203) for receiving rods, and comprising devices for rolling up (30, 40) around rods arranged on either side of the zone of garment (50) being adapted to be moved axially towards each other and apart from each other, each roll-up device comprising several adjacent roll-up arms (31, 41) arranged circumferentially on the drum where each roll-up arm has a proximal end (32, 42) capable of turning the components around the rods, characterized in that the proximal end (32) of each arm of at least one of the roll-up devices ( 30) comprises at least two adjacent toroidal coil springs (321, 322), c each being intended to come into contact with the blank. Figure for abstract: Fig. 1
