  • Patent number: 11498792
    Abstract: The invention relates to a recovery device (10) for recovering sample blanks (P) for a processing machine (1) for processing elements in sheet form, the processing machine (1) comprising: a plurality of work stations (300, 400, 500, 600) including at least one waste removal station (600), and a conveying device (70) comprising a plurality of gripper bars (75) configured to drive the elements in sheet form through the work stations (300, 400, 500, 600), the recovery device (10) being characterized in that it comprises: a first removal belt (94), and a second removal belt (95) arranged after the first removal belt (94) in relation to the direction of travel (D) of the sheets, the second removal belt (94) being able to move between: a continuous-conveying position in which first ends (94a, 95a) of the first and second removal belts (94, 95) are close together so that sheet form element waste (F) can be conveyed from the first removal belt (94) to the second removal belt (95), and a raised position in which

  • Patent number: 10913624
    Abstract: The invention relates to an insert-sheet pick-up device (13) for an insert-sheet loading device (10) of a station for receiving copy (500). The pick-up device (13) includes a suction element (20) configured to pick up an insert sheet. The pick-up device (13) includes a pivoting axis (30) and at least one telescopic arm (33) including a proximal arm (33a), one end of which is fixed to the pivoting axis (30), and a distal arm (33b), able to move with respect to the proximal arm (33a), and one end of which is pivot-articulated to the suction element (20) to move the suction element (20) between a raised position and a lowered position according to a vertical movement of the suction element (20). Also, the invention also relates to an insert-sheet loading device, a copy-receiving station and a machine for processing elements in sheet form including the insert-sheet pick-up device.

  • Patent number: 9061845
    Abstract: A machine for processing elements in sheet form, the machine having chainsets which move gripper bars for moving sheet elements through the machine. At least one tensioner device generates a tension force in the chainsets. The chainset tensioner device includes a drive member capable of generating a variable force, having an intensity dependent on the instantaneous production rate of the machine. Chainset wear is greatly reduced, and the life of the chainsets is lengthened considerably.
