A method for feeding laminar elements into an introducer associated with a graphic printing station provided for printing at least one of the faces of the laminar element, wherein a plurality of laminar elements are grouped in an orderly manner in a stacked group of laminar elements that extends upwards, such that the longitudinal axis of each of the laminar elements is located perpendicular with respect to an advance direction of the group, the advance direction of the group being perpendicular to the advance direction of the introducer. This group of laminar elements is turned 180 degrees with respect to a rotation axis that is parallel to the advance direction of the introducer, such that the upper face of each one of the laminar elements is oriented downwards, the turned laminar element advancing in a direction perpendicular to the advance direction of the introducer.

A divider for dividing a pack of flat-folded cartons into a plurality of stacks of flat-folded cartons, the divider comprising a magazine adapted to hold the carton pack, where the magazine includes a stop member, and where the divider includes a pusher member and a holder foot, where the magazine is arranged in an inclined position, where the pusher member is adapted to compress the carton pack between the pusher member and the stop member, where the holder foot is adapted to bear on the upper side of the compressed carton pack, and where the pusher member is adapted to release the pressure on the carton pack when the holder foot bears on the upper side of the carton pack, thereby creating a low density area adjacent a first carton stack.

When sheet products 1 are discharged, the sheet products are collided against shutter bars 5 so as to fall and stack on a feed conveyor 4. Then, each of protrusion bodies 7 and 8 are lowered by a first drive 9 so as to nip the sheet products between the protrusion bodies and the feed conveyor. Then, coming products are successively discharged and stacked on the protrusion bodies. And then, a second drive 12 is operated in conjunction with the feed conveyor so as to feed the sheet products nipped between the protrusion bodies and the feed conveyor 4. The shutter bars 5 are elevated and lowered by a third drive for adjusting the height position thereof.

The present disclosure is generally related to an apparatus having cutter elements for destroying articles such as paper sheets and a mechanism for separating at least a sheet from a stack in a tray. The separation mechanism can be activated by rotation of the cutter elements. In one embodiment, the separation mechanism is provided in the form of a helical mechanism configured for insertion into the stack and to receive separated sheets from the stack in between its space(s) as it is rotated. The separated sheets can fall via gravity into the shredder mechanism. Optionally, a paper feed mechanism can feed separated paper to the cutter elements. The tray can include an edge to assist in directing separated paper towards the cutter elements. One or more staple picking support mechanisms can also be provided to assist in separating sheets from a stapled set of pages.

A portioning system for portioning stackable flat carton elements in a stack (101) for further processing. A feeder device (105) includes a lifting platform (106) and a pushing platform (107), wherein the feeder device (105) is movable along a linear path (108) for pushing the stack (101) to a delivery position. The feeder device (105) is further movable along a lifting direction (110) having at least a component parallel to the gravity direction. The feeder device (105) is configured such that the lifting platform (106) is movable partially below the flat elements defining the stack (101) such that an edge portion (111) of the stack (101) is arranged on the lifting platform (106) for being liftable by the lifting platform (106). The feeder device (105) is further configured such that the stack (101) is pushable by the pushing platform (107) along the linear path (108) until the stack (101) is arranged at the delivery position.

The invention concerns a method of handling stacks of flexible substrates (14) by means of a gripper (8) as well as a robot cell (1) for carrying out the method. The gripper (8) is arranged on an arm (6) of a robot (2) and has a lower finger and a corresponding upper finger. The method comprises the steps of inserting said lower finger below a bottom substrate (14) of a stack resting on a base and said upper finger above a top substrate (14) of the stack, and gripping the stack by clamping it between said lower and upper finger. Then by means of the gripper (8) starting at a stack front the entire stack is lifted into a pendent state and moved to a support (16). There the stack is lowered such that a stack rear, which is opposite to said stack front, comes into contact with the support (16). Finally the entire stack is laid out on the support (16) with said bottom substrate (14) up by further lowering and while horizontally displacing the gripper (8) in a bottom-to-top substrate direction before letting the gripper (8) release the stack.

A feeder system for feeding a stack (101) of stackable flat, carton elements to a processing device: A delivery ramp (103) includes a receiving surface (104) on which an edge portion (111) and a center portion (116) of the stack (101) is arrangeable. A transport device (125) includes a supporting platform on which at least a further edge portion (115) of the stack (101) is supportable, wherein the supporting platform is arranged adjacent to the receiving surface (104) such that the further edge portion (115) of the stack (101) may be received. A downholder element (117), adjusts a size of a gap (705) between the downholder element and a supporting platform, such that the further edge portion (115) of the stack (101) is clampable between them. The transport device (125) is movable between the receiving position, at which the stack (101) may be received by the delivery ramp (103), and a hand over position at the processing device such that the stack (101) is movable from the receiving position to the hand over position.
