There is described a method for applying foil material () onto successive sheets (S), especially sheets for the production of securities, such as banknotes. In a first step, individual sheets (S) are transported in succession along a sheet transport path. In a second step, at least one continuous band of foil material () is applied onto the individual sheets (S) along a direction substantially parallel to a direction of displacement (A) of the individual sheets, thereby forming a continuous flow of sheets linked to one another by the said at least one continuous band of foil material (). In a third step, the said at least one continuous band of foil material () is cut by means of a laser beam (L) such that the continuous flow of sheets is again separated into individual sheets (S) with portions of foil material (*) remaining on the sheet. The cutting is performed at positions located on the sheets (S) such that said portions of foil material (*) remaining on the sheets do not extend beyond leading and trailing edges of the sheets (S). Waste portions () of said at least one continuous band of foil material () that are not to remain on the sheets (S) are seized prior to cutting by the laser beam (L) and are held throughout the cutting process. There is also described an installation for carrying out the above method.

The invention relates to devices for aligning sheets (), which are overlapped with an offset and supplied to the device by a stream feeder and which can be transferred to a device () that is located downstream, after alignment of the front edge and one lateral edge of the sheets. At least pant of a sheet can be brought to rest on the periphery of an alignment cylinder (), which is used to align the front edge of the sheet by means of front lay marks located on the periphery of said cylinder. At least one recess is provided on the periphery of the alignment cylinder, which, by the application of a negative pressure to said recess allows at least part of the sheet to be fixed by friction on the periphery of the alignment cylinder, in such a way that in the contact zone, drive forces from said cylinder can be transferred by friction to the sheet. A measuring device () determines the offset of a lateral edge of the sheet in relation to a predetermined set alignment. A transversal displacement device is used to align a lateral edge of the sheet in accordance with the measurement result of the measuring device. The acceleration and/or speed and/or angle of rotation of the drive motor for driving the rotation of the alignment cylinder can be controlled or adjusted according to predetermined laws of motion, in particular in accordance with the angle of rotation of the alignment cylinder.

Devices for aligning sheets

Sheets which are overlapped with an offset are supplied to a device for the continuous alignment of sheets by a stream feeder. After alignment of at least the front edge and one lateral edge of each sheet, the sheets can be transferred downstream to a following device.

Device and a method for aligning sheets

The invention relates to a stacking device for a machine for processing sheets, especially a sheet printing machine. Said device can be displaced between a first stacking position () and a second stacking position (), and comprises carriers for a pallet receiving the stacked sheets in the first stacking position () and the second stacking position (). The inventive device also comprises transport units () for transporting the pallets () from each stacking position () to a single pile of pallets (), and for stacking the pallets () in the pile of pallets ().

The machine further comprises a paper sheet feed device, a device for transporting the paper and a unit for applying security images (,) supported by at least one ribbon (,a). The ribbon is brought into contact with the paper (,) so that the images (,) are applied at determined points on the paper. The application unit comprises an applicator cylinder (,) fitted with pads (,) in register with determined points on the sheets (,) and cooperates with a press cylinder (,), between which cylinders the paper (,) passes. The ribbon (,a) is mounted between two reels (B,, B,) for paying out the ribbon and (,) for winding up the ribbon. The machine is equipped with a device (,) for preheating the ribbon (,a) upstream of the applicator cylinder (,) so as to preheat the images (,) which will be applied to the sheet of paper (,) by simple contact of said pads (,) with the images (,) against the press cylinder (,).

Machine for security printing on security paper

An inner blanket securement assembly utilizes spaced inner blanket engaging pins and an inner blanket hold-down device with a hook-shaped holding nose to secure an edge of an inner blanket to a cylinder. The inner blanket is structured using a plurality of inner layers within an outer casing that is closed and bag-shaped adjacent the leading edge of the inner blanket.
