Ink Roller

The invention relates to an ink roller for inking unit of an offset printing press in which the inking roller includes a number of areas arranged in the direction of the axis of rotation and at least one ink reservoir inside the inking rollers. In each of the various zones, at least one ink tank is connected to at least one ink outlet in the circumferential surface of the inking rollers. In units of ink offset printing presses, ink is usually supplied by a source of ink or the ink to a group of roller inking unit through an ink roller ink and measuring devices arranged along the axis of rotation of the source of ink

roller. Different amounts of ink are provided for different areas governed by the measuring devices assigned individual ink to the individual zones as selected in accordance necessary to calibrate with precision, yet the manufacturing tolerances result in a given work and therefore in environments that are difficult to reproduce after certain time (including zero), in particular, if the ink metering device must be disassembled for maintenance. Also, the cost of Such ink, measuring element is considerable. An inking roller according to the invention for a inking unit of an offset printing press has a number of areas arranged in the direction of the axis of rotation of the inking rollers and at least one tank ink inside the ink roller. The at least one ink reservoir in each of the various zones are connected to at least one ink outlet in the circumferential surface inking roller so that the ink present in the ink may reach the circumferential surface of the ink roller. At least one pumping element for transport ink from the ink reservoir to the circumferential surface is assigned to each area and located in each zone within the inking rollers. The inking unit according to the invention constitutes a simple system that has very few components and does not cost much. Advantageously, the assembly of the inking roller requires less precision mechanical common ink metering devices. The hardness of the inking rollers must be maintained between 28 Shore A to a maximum of 32 Shore A, with tolerance of ± 5 Shore A. Most inks are oil-based rubber is ideal for the oil to be nice.
