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.

A cardboard dispensing apparatus for providing cardboards at a food product supply area comprises a cardboard store for storing cardboards that form a cardboard stack, a cardboard buffer storage for storing a plurality of cardboards, and a cardboard conveyor for conveying the cardboards from the cardboard buffer storage to the food product supply area. A cardboard extracting device is configured to extract cardboards from the cardboard store and move the cardboards into the cardboard buffer storage, while the cardboard conveyor is configured to remove the cardboards from the cardboard buffer storage and convey them to the food product supply area.

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 method for supplying plate elements to a machine for processing the plate elements, from an initial pile of elements, the method includes: pushing a first batch of plate elements, from the top of the pile, downstream until the first batch comes at a storage capable of storing the first pushed batch, and simultaneously, displacing the storage downstream over a distance corresponding to the length of the first batch to separate the first batch from the pile; and thereafter transferring the elements of the first batch one after the other to the machine.

A main object of the invention is to provide a sheet material separation-aiding apparatus that ensures that there can be a gap produced stably between a specific sheet material from a stack of sheet materials and a sheet material just below it, and that achieves size reductions, reduced energy consumptions and a decreased parts count. As shown in FIG. 4, the sheet material separation-aiding apparatus 1 comprises a rotating means 2 including an abutment portion 21 that is capable of coming in abutment on an end of the uppermost sheet material 101, a supporting means 3 that supports the rotating means 2 in a rotatable manner and is capable of moving in a vertical direction, a biasing means 4 that biases the supporting means 3 in a downward direction, and a lifting means 5 that lifts up an end 23 of the rotating means 2 in opposition to the abutment portion 21. As the end 23 is lifted up, it causes the rotating means 2 to rotate with the abutment portion 21 coming in abutment on the end of the sheet material 101, and as the end 23 is further lifted up, it causes the supporting means 3 and rotating means 2 to keep on going up while the rotating means 2 is kept from rotation by a counterforce that the abutment portion 21 receives from the sheet material 101.
