SYSTEM OF PRINTING, SYSTEM OF SHEET PROCESSING AND DEVICE FOR CHANGING SHEET DIRECTION Russian patent published in 2014 - IPC B41J15/18 

FIELD: polygraphic industry .

SUBSTANCE: system includes the first input unit and the second input unit, which are both used to introduce a sheet in the first direction, with the first input unit and the second input unit being close to each other. Direction of the sheet movement is changed from the first direction to the second direction by a unit of direction changing. The first output unit and the second output unit, into which sheets are brought in the second direction, are provided. The unit of direction changing changes direction of the sheet movement from the first to the second direction. In case of two-sided printing a sheet, supplied from the first input unit, is subjected to printing on its first side in the first printing device, and its movement direction is changed in the unit of direction changing, with the sheet being reversed and after that subjected to printing on its second side in the second printing device and is output into the second output unit. In case of one-sided printing a sheet, supplied from the first input unit, is subjected to printing on its one side and its movement direction is changed in the unit of direction changing, and after that the sheet is output into the first output unit. Direction of movement of the sheet, which was supplied from the second input unit, is at the same time changed in the unit of direction changing, and the sheet is subjected to printing on its one side in the second printing device and is output into the second output unit.

EFFECT: possibility to perform processing of sheets such as high-speed printing.
