  • Patent number: 6682065
    Abstract: 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.
