Abstract:
There is described a method for applying foil material (200) onto successive sheets (S), especially sheets of securities. 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 (200) is applied onto the individual sheets (S) along a direction substantially parallel to a direction of displacement 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 (200). In a third step, the said at least one continuous band of foil material (200) is cut by means of a laser beam such that the continuous flow of sheets is again separated into individual sheets (S) with portions of foil material (200*) remaining on the sheet. The cutting is performed at positions located on the sheets (S) such that said portions of foil material (200*) remaining on the sheets do not extend beyond leading and trailing edges of the sheets (S). Waste portions (205) of said at least one continuous band of foil material (200) that are not to remain on the sheets (S) are evacuated by aspiration, evacuation being carried out by direct aspiration of the waste portions (205) at least at a first position located downstream of and proximate to a cutting position where said at least one continuous band of foil material (200) is cut by the laser beam. There is also described an installation for carrying out the above method.
Abstract:
There is described a delivery unit (20) for sheet-fed printing or processing machines comprising several delivery piles (21.1 to 21.3) disposed one after the other along a sheet delivery path. A transporting system is provided for transporting the sheets along the sheet delivery path, and sheet-delivery control means for selectively delivering the sheets in any one of the said delivery piles. The delivery piles are built in a modular fashion, each delivery pile being constructed as an independent delivery module with individual sheet transfer means for assisting transport of the sheets along the sheet delivery path. Individual control means are provided for selective delivery of the sheets in the delivery pile. The delivery unit further comprises an adaptation unit (22) for adapting the delivery piles to a printing or processing unit.
Abstract:
The invention relates to a method and a device (01) for the continuous alignment of sheets, which are overlapped with an offset and supplied to the device by a stream feeder. After alignment of at least the front edge and one lateral edge of the sheet, said sheets can be transferred to a device (36) that is located downstream.

Abstract:
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 (02) and a second stacking position (03), and comprises carriers for a pallet receiving the stacked sheets in the first stacking position (02) and the second stacking position (03). The inventive device also comprises transport units (14, 16, 18) for transporting the pallets (09, 21) from each stacking position (02, 03) to a single pile of pallets (11), and for stacking the pallets (12, 19) in the pile of pallets (11).
Abstract:
There is described a method for applying foil material (200) 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 (200) 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 (200). In a third step, the said at least one continuous band of foil material (200) 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 (200*) remaining on the sheet. The cutting is performed at positions located on the sheets (S) such that said portions of foil material (200*) remaining on the sheets do not extend beyond leading and trailing edges of the sheets (S). Waste portions (205) of said at least one continuous band of foil material (200) 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.
