摘要:
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.
摘要:
A process and device are disclosed for assessing the quality of processed sheets. The sheets to be inspected are tautly held on a drum during inspection.
摘要:
The invention relates to a device for cutting paper webs (01) for forming several partial webs. The inventive device is arranged between an output of a printing machine and the input of a folder for folding the cut partial webs. Said device comprises a water jet cutting appliance (10).
摘要:
A pallet (03) comprising a support plate (21) provided with supporting projections (26) which are arranged on the main side thereof which is configured as a supporting surface (19) for bearing a load, said projections being tapered towards a free end thereof, enabling supportive contact to be established with a second pallet (03) selectively at a small or imperceptible first distance or a large second vertical distance between said pallets (03). In order to receive the supporting projections (26), recesses (33) are formed on the second main side of the pallet (03) opposite the supporting surface (19).
摘要:
A printing unit has two screen printing cylinders (12, 17) and a printing gap (14) formed by two cylinders (9, 16). At least the second cylinder of the two cylinders that form the printing gap is a transfer cylinder which co-operates with the second screen printing cylinder. A screen printing cylinder for the printing unit has a screen (23), a doctoring device which is situated radially inside said screen and a support element (36) which extends axially on the screen printing cylinder in the area of a limited peripheral section and which is used for sustaining a pressure exerted radially, outwards on the screen by the doctoring device when the limited peripheral section passes in front of said doctoring device.
摘要:
The invention relates to a device and method for processing valuable documents. According to the invention, a sheet (02) printed with individual banknotes is cut into strips (03). These strips (03) are inspected and subsequently cut into individual banknotes.
摘要:
The invention relates to a cylinder drive (01, 02) of a rotary printing press. According to the invention, a friction torque which is produced by a process-related friction gear (03, 04) is approximately compensated with an additional friction torque of a second friction gear (06, 07).
摘要:
In a web guiding system for a rotary printing press, printed webs, in particular, are deflected without smearing in that the acting diameter of a rubber-covered cylinder of a printing mechanism corresponds to the diameter of a driven web guiding roller or, in certain conditions, to an integral multiple of this diameter.
摘要:
The invention relates to a method for the regulation of a web tension in a rotary print machine, whereby the web (B) passes through at least two printing groups (06, 07, 08, 09). A change in the extension of the web during the run, is determined by means of a change in a phase shift between a first phase position of a printing group and a second phase position measured behind a last printing group. The change in phase position is compensated by means of a change in the tension (S) of the web before the first printing group.
