摘要： The invention relates to a method and a device for conveying sheets in a sheet-fed printing press. The invention provides a method and a device to convey sheets unmarked on their printing surfaces by means of conveyor and/or positioning element even when the sheet is immediately run through the printing press a second time. According to the invention, this is performed in that the sheet to be printed is exclusively grabbed by a gripping edge during its trajectory (conveyance and positioning).

摘要： The invention relates to a device for feeding sheets from a sheet pile to a sheet conveyor drum of a printing machine. The invention seeks to create a device to feed sheets with high feeding performance and low dynamic load. According to the invention, this is performed in that a conveyor element is placed above the sheet pile, configured as a suction box and connected to a lever mechanism, grabs the respective top sheet on the sheet pile, separates the sheet from the sheet pile and conveys the sheet across a feed table to lay marks; and in that, underneath the plane of the feed table, a pre-gripper, configured as an oscillating suction element, grabs the sheet to be conveyed, accelerates its conveyance and delivers the sheet to the sheet conveyer drum.

摘要： The invention relates to a printing machine with at least one integrated device to print a printed form from a printing cylinder. The aim of the invention is to create a printing machine with a compact design. This is achieved by arranging the cylinder groups (11) symmetrically in relation to a horizontal α bisecting line (12) of an angle (α) formed by the connecting lines of the centers of the offset cylinders (9) with the center of the printing cylinder (13).

摘要： The invention relates to a method for printing the front and the reverse side of a sheet. The invention provides a method for printing the front side of the sheet and subsequent printing of the reverse side thereof without requiring great mechanical and technical means or excessive handling. According to the invention, this is performed in that the sheet to be printed is taken out of the sheet feed pile (1), passed on to the sheet guide cylinder (4) to print the reverse side of the sheet. Once the reverse side of the sheet is printed, it is forwarded to the sheet exit pile (11) in the direction opposite to the running direction of the sheet towards the sheet guide cylinder (4), by a sheet transporting device (15). It is then deposited in the sheet exit pile (11) placed before the sheet feed pile in an equal plane relative to the running direction (14) of the sheet, the printed reverse side facing upwards. The sheet exit pile (11) can be brought to the position of the sheet feed pile for consecutive printing of the front side of the sheet.

摘要： The invention relates to a short inking mechanism for flatbed rotary presses, comprising a roller with a structured lateral surface (e.g. an intaglio printing roller), ink ducts, a doctoring device and a form roller with a rubber elastic envelope. The aim of the invention is to provide a short inking mechanism with a structured roller e.g. an intaglio printing roller or a hatching roller. This is achieved in the following manner: the maculation rings of the roller with the structured envelope surface can be pre-stressed with the maculation ring of the form roller associated therewith, whereby said rings roll onto each other during operation.

摘要： The invention relates to a printing machine comprising a sheet feeder, elements for conveying a sheet to be printed to a feed line, feed mechanisms for conveying sheets from the feed line to a printing cylinder having a diameter which is three times larger and provided with printing surfaces, at least one cylinder group interacting with the printing cylinder and consisting of a double-sized offset cylinder, a double-sized printing cylinder or a double-sized printing form cylinder, each having two working surfaces, a device for printing a printing form arranged on a printing form cylinder and a sheet exit unit containing an output chain circuit. The aim of the invention is to design a sheet path in a conventional printing machine ranging from the printing cylinder to the sheet pile in such a way that the sheet can be further processed. To do this, the sheet discharge device (26) contains two delivery drums (15, 16) arranged downstream from the printing cylinder (6) and upstream from the sheet exit unit (25) and by assigning special devices (28), it is possible to influence the sheet in a selective manner on the second delivery drum, i.e. by arranging a drying device (29) to dry the sheet (10) or by arranging a cutting device (38) to separate the sheet (10) in the middle, or by arranging a powder device (24) to powder the sheet (10), or by arranging an application device (18) to coat the sheet (10) or to provide it with another color.

摘要： The invention relates to a method and a device for feeding sheets (1) from a sheet pile (2) to a sheet conveyor drum (3) of a printing machine. The invention seeks to create a method and a device to feed sheets (1) in high-speed machines showing greater feeding accuracy even in case of thin printing material and reduced overall dimensions. According to the invention, this is performed in that each top sheet (1) to be fed of the sheet pile (2) is grabbed by a conveyor element (6), separated from the sheet pile (2) and transported in the direction of the printing machine through a feed table (9) up to the lay marks (10), the sheet then being released from the conveyor element (6), positioned, caught by a pre-gripper (13), accelerated and conveyed to the sheet conveyor drum (3).

摘要： The invention relates to stacking logistics for a printing machine to print the front side of sheet and the reverse side of a sheet. The aim of the invention is to create stacking logistics for a printing machine whereby the front side of a sheet is printed first, followed by the reverse side of a sheet. According to the invention, this is achieved by putting the stacks on conveyor trolleys assigned to a common stacking plane and placing a cantilever arm with a vertical drive mechanism in the side areas of the feeder stack and the exit stack on both sides, symmetrical to the machine's longitudinal axis and locating it below the respective assigned conveyor trolley.
