The invention relates to an apparatus, in particular a roll cross cutter, for forming a shingled stream of underlapping or overlapping sheets, in particular paper or cardboard sheets, comprising a transport device for transporting sheets, a shingling device for underlapping or overlapping of the sheets at least in some regions, a braking device following the shingling device in the transport direction of the sheets for braking of shingled sheets, in particular by the formation of a brake gap for the passage of sheets brought together in a shingled manner, and a cross-cutting device upstream of the shingling device for cutting a material strip into individual sheets. According to the invention, an intake section is provided between the shingling device and the braking device for intake and further transport of a sheet, trailing in the shingled stream, into the braking device.

A diverting system is proposed for diverting boxes from normal production flow. One embodiment comprises a diverter with a diverter surface, a diverter cam in contact with the diverter, a diverter cam shaft connected to the top diverter cam such that rotation of the diverter cam shaft causes rotation of the diverter cam, and an electric motor connected to the diverter cam shaft and configured to rotate the diverter cam shaft. The diverter cam is configured to control position of the diverter as the diverter cam rotates such that rotation of the diverter cam causes the diverter surface to move from a position above normal production flow to a diverting position within the normal production flow.

A packaging machine having several work stations, a transport chain and a chain deflection pulley on which the transport chain is mounted. The transport chain comprises chain clips, each chain clip having an upper part and a lower part, wherein the upper part and/or the lower part may be moveable relative to each other to move the chain clips between an open position and a closed position. The material blank may be introduced into the open chain clips and secured in the closed chain clips to transport the material blank in a direction of transport using the transport chain. A chain opening mechanism may be actively and operably changed between an opening state and a closing state in order to open and close at least one chain clip disposed on a planar oriented section of the transport chain and/or to maintain an already opened chain clip in an open state.

A method for operating a packaging machine including one or more of the method steps advancing a transport chain along a chain deflection pulley, wherein chain clips are arranged on the transport chain and moved during the advancing motion of the transport chain along a run-on contour, to open at least one of the chain clips; introducing a flat material blank into the at least one open chain clip using a feed device or by entraining the flat material blank using a connection to a second material blank preceding the flat material blank, wherein the material blank enters the open chain clip during an advancing motion of the transport chain; closing the chain clip by leaving the run-on contour, to grip and secure the material blank in the chain clip; and transporting the material blank to a work station using the transport chain.

Apparatus for automatically unstacking a pallet on which at least two stacks of blanks are arranged. The apparatus comprises an unstacking station which is configured for receiving a pallet on which are arranged at least two stacks of blanks in collapsed condition. The unstacking station is further configured for taking off one by one individual blanks from the at least two stacks of blanks which are on a pallet received in the unstacking station. The apparatus further includes a feed track for conveying pallets. The feed track links up by a discharge end with the unstacking station for the purpose of feeding a pallet with stacks of blanks to be unstacked to the unstacking station. Further, the apparatus includes a blank main discharge assembly for discharging individual blanks to a further processing station.

An automatic loader for delivering vertically stacked media to a hopper of a feeder. The automatic loader includes a powered conveying device, actuated plates, a first sensor, and a second sensor. The first sensors detects a height of the vertically stacked media that is in the hopper, and the second sensor detects a separation between the hopper and the vertically stacked media that is in a staging area of the conveying device. Based on signals generated by the first and second sensors, the conveying device automatically delivers the vertically stacked media that is in the staging area to the hopper of the feeder.

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 paperboard sheet and a method of using the paperboard sheet is provided in which a surface of the paperboard sheet provides a pattern of indentations, the indentations reducing the surface area between adjacent sheets to facilitate the transfer of a top sheet from a stack of similar sheets.

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.

Provided are a sheet stacking device, a counter ejector and a box making machine, wherein: a hopper unit stacks sheet-like cardboard boxes; feeding rolls feed a cardboard box to the hopper unit; and a guiding device is disposed between the feeding rolls and the hopper unit and includes a first guide part that extends in a horizontal direction and guides a lower surface of the cardboard box and a second guide part that extends in a vertical direction and guides a rear end of the cardboard box. Due to this configuration, the occurrence of damage to box making sheets in high-speed conveying of the box making sheets can be suppressed and the box making sheets can be appropriately stacked in a prescribed posture.
