INKING APPARATUS OF PRINTING PRESS, PRINTING PRESS COMPRISING SAME AND METHOD OF PRODUCING VIBRATOR ROLLER Russian patent published in 2019 - IPC B41F31/04 

FIELD: printing equipment.

SUBSTANCE: disclosed is a printing device of a printing machine, in particular an offset printing machine or a high-printing machine, comprising at least one ink box with an ink feed roller, a recoiling apparatus comprising at least one ink roller receiving ink from at least one ink box, and at least one transfer roller located between the ink supplying roller and the ink roller, wherein said transfer roller is reciprocally pivotable between the ink supplying roller and the ink roller and intermittently transferring ink from the ink supply roller onto the ink roller. Transfer roller circumference has a paint transfer structure which reflects the required profile of rolling the ink on the printing plate to be rolled by a paint device, and structurally designed to control amount of paint carried by transfer roller. Structure for transfer of paint on circumference of transfer roller is subdivided in circumferential direction of transfer roller to integer number of separate parts for transfer of paint, repeated through predetermined circumferential period in circumferential direction, wherein each separate part for transfer of paint reflects required profile of rolling of paint on printing form, subject to rolling of paint by means of paint device.

EFFECT: contact length on which the transfer roller comes into contact with the ink feed roller is equivalent to a certain circumferential period of the separate parts for transfer of paint or the whole multiple of this definite period of period of separate parts for transfer of paint.
