摘要： A rotary cylinder printing press in which the disadvantages incurred by having to stop each sheet to set it in registration with the printing cylinder are overcome by carrying the longitudinal register on a transfer cylinder so that the sheets can be set in exact register with the printing cylinder without stopping. The transfer cylinder is rotated continuously in the same direction and its speed is varied cyclically as each sheet is set in register and then transferred to the printing cylinder. The transfer cylinder is also provided with a safety system which detects misalignment of sheets or damaged sheets to prevent the transfer cylinder from conveying such sheets to the printing cylinder.

摘要： The excess of damping liquid taken from the vessel 3 by the fountain roller 4 which rotates in the direction indicated by the arrow 6 is removed by the wiper element 9 formed of a body made of elastic material of circular cross section housed in a longitudinal groove in the rigid support bar 11. The fountain roller is rotated by the dc motor 5, the speed of which is adjusted by pulses coming from the processor 23 under the influence of the signal transmitted to the processor by the speed detector 23 which is located on the shaft of the plate roller 1. The speed can also be influenced by other signals transmitted to the processor, for instance from the keyboard 30 where it is possible to enter data relative to different characteristics of the equipment and of the damping liquid, for instance according to its viscosity. The fountain roller transfers the liquid to the duct roller 7, the peripheral speed of which is equal to that of the plate roller, or to the first of the rollers of the inking system. The wiper element is subjected in three zones of its length, preferably separated by equal spaces, to the thrust of the rods of three membranes actuated by pressure fluid. To each of these membranes can be applied a pressure which is adjustable by means of a regulating device 21 controlled by pulses coming from the processor which are created therein based on information transmitted to said processor, for instance by detectors of the relative humidity of the air and the temperature on the opposite sides of the machine and at the intermediate part thereof or in response to signals transmitted to the processor by the scanner 25 of the plate at three different strips on the peripheral surface of the plate (FIG. No. 2).
