The invention concerns a device for feeding objects which have the shape of essentially flat but flexible sheets (1) or blanks of sheet material, piece by piece from the top of a magazine (24) consisting of a plurality of such objects which are arranged on top of one another, comprising separation means (31a, 31b, 27a, 27b) for parting the uppermost object from the underlying objects in the magazine, before it is moved from the magazine, and first motion devices (42, 43, 44, 45) for removing the parted uppermost object from the magazine. A characteristic feature is that said separation means comprises members provided to bend the uppermost object (1a) to adopt an upwardly convex shape, while the adjacently underlying object is bent to a less convex shape than the uppermost object, or remains at least essentially flat, before the uppermost object has been removed from the magazine.
L'invention concerne un dispositif d'alimentation en objets en forme de feuilles souples sensiblement plates (1) ou de découpes de matériau en feuille, pièce par pièce depuis le sommet d'un magasin (24) comprenant plusieurs objets qui sont disposés en pile. Ledit dispositif comprend des moyens de séparation (31a, 31b, 27a, 27b) conçus pour séparer l'objet le plus haut des objets situés au-dessous dans le magasin, avant qu'il soit enlevé du magasin, et des premiers dispositifs de mouvement (42, 43, 44, 45) conçus pour enlever l'objet le plus haut du magasin. Le dispositif de l'invention se caractérise en ce que les moyens de séparation comprennent des éléments conçus pour déformer l'objet le plus haut (1a), de sorte qu'il prenne une forme convexe et que l'objet se trouvant directement au-dessous prenne une forme moins convexe ou reste sensiblement plat, avant que l'objet le plus haut soit enlevé du magasin.
