  • 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.

  • Patent number: 6609352
    Abstract: A machine for manufacturing packages for compact discs or similar out of cardboard work piece. The packages consist of a casing part and a slide part inserted therein, with a compact disc and a booklet. These two components are manufactured in separate tracks (A, B), which consist of jigs, whereby each of these rotates stepwise in a rotating table. The casing parts are manufactured by laying down the forward half of a work piece on a placing plate (1), laying down a cover (2) over this, the cover having the same outer shape as the inside of the finished casing, folding its edge upwards with first folding devices (7), folding over its edge with second folding devices (9, 10) applying melt glue on the top flap and laying down the rear half over disc, and squeezing by means of the second folding devices until the glue has stuck.
