A medium feeding device includes a storage unit that stores media in a form of a sheet, a delivery unit that is disposed downstream in a medium delivery direction relative to the media stored in the storage unit and that delivers the media individually, a transfer unit that is disposed above the storage unit and that sticks by suction to each of the media stored in the storage unit and transfers the media to the delivery unit individually, and a fluffing unit that is disposed beside the media stored in the storage unit in a direction intersecting the medium delivery direction. The fluffing unit fluffs an upper-side region of the media in a state of being separated by blowing air toward a side of the media. The medium feeding device further includes plural position detection units that are arranged in a region that is on the delivery unit side relative to a position of a downstream end portion, in the medium delivery direction, of each of the media stored in the storage unit and that does not reach a contact portion where the delivery unit comes into contact with the media. The position detection units are arranged at an interval in a width direction of the media intersecting the medium delivery direction. The position detection units detect a position of the downstream end portion, in the medium delivery direction, of each of the media.

The present invention relates to a method to remove an adhesive label (22) from a bobbin (28), the bobbin including an end portion (24) and an outer surface (25), the method including: providing a bobbin of a coiled sheet closed by an adhesive label positioned on top of the end portion of the coiled sheet (26) to attach the same to the outer surface of the bobbin; locating the adhesive label; applying a sucking force to the location of the adhesive label so as to detach the adhesive label and the end portion of the coiled sheet from the bobbin; and cutting a part of the detached end portion including the adhesive label from the bobbin. The present invention also relates to an apparatus to detach an adhesive label from an end portion of a coiled sheet in a bobbin, the adhesive label being located between the end portion and an outer surface of the bobbin.

A sheet stacking apparatus includes a sheet alignment mechanism configured for aligning a sheet in a predetermined reference position; a gripper arrangement configured to grip the aligned sheet at at least two spaced-apart points of the sheet and to release the sheet on a stack; and a holder configured to hold the sheet in position on the stack while the gripper arrangement releases the sheet. The gripper arrangement is movable along a predetermined trajectory for moving the sheet from the reference position to a stacking position.

Example printer finishing apparatus are described herein. An example printer disclosed herein includes an alignment guide, a track to align a sheet relative to the alignment guide, a clamp to move between a raised position and a lowered position relative to the sheet, and a force applicator coupled to the clamp. The force applicator is to cause the sheet to engage the alignment guide when the clamp is in the lowered position.

An inkjet printing machine for printing individual sheets comprises at least one printing station and a transport system defining a transport track for transporting the individual sheets through the printing station, along a transport direction. The transport system comprises a plurality of gripper conveyors (150) running along the transport track for holding the individual sheets during a printing process in the printing station. Each of the gripper conveyors (150) comprises an energy storage (161) for providing energy for operating a gripper mechanism (171) of the gripper conveyor (150). The printing machine allows for efficient and flexible handling of individual sheets, in particular large format sheets of materials such as corrugated cardboard or other materials that have a certain degree of inherent stability.

A printing apparatus includes a feeding roller configured to feed a printing sheet stacked on a stacking unit, a conveyance roller configured to convey the printing sheet fed by the feeding roller, a printing unit configured to print the printing sheet conveyed by the conveyance roller, a conveyance control unit configured to control conveyance of printing sheets so that the trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and the leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other, and a determination unit configured to determine whether to convey the succeeding sheet to a position facing the printing unit while keeping an overlap state between the preceding sheet and the succeeding sheet.
