PRINTING MACHINE FOR INTAGLIO PRINTING Russian patent published in 2017 - IPC B41F13/00 

FIELD: printing industry.

SUBSTANCE: proposed printing machine for intaglio printing, comprising a plate cylinder, on which one or more intaglio printing plates are installed, and the paint for the plate cylinder comes from the inking unit containing several templates cylinders, which directly or indirectly transfer ink to the plate cylinder, the printing gravure printing machine includes adjustment system acting on the patterned cylinders to compensate the elongation of one or more intaglio printing plate. The adjustment system comprises a steering actuator cylinder for each pattern, wherein the adjustment actuator is disposed between the cylinder template, performing the function of a rotating variable drive output body, and the drive gear, which performs the function of rotating the input variable drive body. Adjustable drive for selective adjustment generic cylinder rotation frequency relative to the frequency of rotation of the drive gear. The position of adjusting the controlled drive of actuation in rotation of the cylinder is regulated on each turnover of the template cylinder using the adjustment cylinder engine of the controlled drive. In uncontrolled position of the regulated drive, the adjusting motor is turned off, and driving rotation of template cylinder is exclusively mechanically controlled by the drive, wherein the templated cylinder rotates at the same rotational speed as the drive gear.

EFFECT: increase control system reliability.
