The invention concerns a device for setting sleeves on objects moving past, said sleeves being sectioned from a continuous sheath (13) passing on a shaping device opening the floating sheath. The invention is characterised in that the rollers (30, 31) lowering the sheath and the rollers (32, 33) ejecting the cut off sheath section (15) are driven in rotation by associated electric motors (41; 42, 43) whereof the control is synchronously produced by a common electronic programmer (50) arranged for determining a continuous profile of speed variation so as to control the lowering of each sheath section, said programmer including at least a control card (55) co-operating with an adjacent encoder (47) mounted at the end of a shaft (46) driven in rotation by a central gear motor (40, 45). The resulting synchronisation enables to obtain very high speeds with a sleeve diameter hardly greater than the maximal diameter of the objects.

L'invention concerne un dispositif de pose de manchons sur des objets en défilement, lesdits manchons étant tronçonnés à partis d'une gaine continue (13) passant sur un conformateur (20) d'ouverture de gaine du type flottant. Conformément à l'invention, les galets (30,31) de descente de gaine et les galets (32,33) d'éjection du tronçon de gaine coupé (15) sont entraînés en rotation par des moteurs électriques associés (41; 42, 43) dont la commande est réalisée en synchronisme par un programmateur électronique commun (50) agencé pour déterminer un profil continu de variation des vitesses, afin de piloter la descente de chaque tronçon de gaine, ledit programmateur incluant au moins une carte de commande (55) qui coopère avec un codeur adjacent (47) monté en bout d'un arbre (46) entraîné en rotation par un groupe moto-réducteur central (40,45). La synchronisation obtenue permet d'envisager des cadences très élevées avec un diamètre de manchons à peine supérieur au diamètre maximal des objets.
