GRAVURE PRINTING MACHINE WITH MOBILE TROLLEY THAT SUPPORTS COLLECTING CYLINDER FOR DYE Russian patent published in 2015 - IPC B41F13/00 

FIELD: printing industry.

SUBSTANCE: gravure printing machine is proposed, comprising a stationary machining frame supporting a plate cylinder and an impression cylinder in contact with the plate cylinder. The dyeing system for applying dye to the plate cylinder, where the dyeing system comprises the collecting cylinder for dye, is designed to contact with the plate cylinder, and at least one inking unit for device for feeding the dye to the said collecting cylinder for dye. At least a first mobile trolley supporting the collecting cylinder for dye, where the first mobile trolley is adapted to move relative to the stationary machining frame between the working position in which the collecting cylinder for dye contacts the plate cylinder, and a retracted position in which the collecting cylinder for dye is removed from the plate cylinder. The axis of rotation of the collecting cylinder for dye lies below the horizontal plane intersecting the axis of rotation of the plate cylinder. The first mobile trolley is adapted to move along the direction parallel to the horizontal plane. And the plane intersecting the axis of rotation of the collecting cylinder for dye and the axis of rotation of the plate cylinder forms in the working position of the first mobile trolley an acute angle relative to the horizontal plane.

EFFECT: improvement of quality of printing.
