Abstract: There is disclosed a method of feeding a dampening water to a plate cylinder in an offset printing press which is accelerated to, operated at and then decelerated from a predetermined speed for printing. The method comprises the step of programmatically controlling the feeding amount of the dampening water to increase in accordance with the increase in speed of the printing press along a first curve which is predetermined to indicate the relation of the feeding amount of dampening water to the speed of printing press, when the printing press is accelerated. The method further comprises the step of programmatically controlling the feeding amount of the dampening water to decrease in accordance with the decrease in speed of the printing press along a second curve which is predetermined to indicate the relation of the feeding amount of dampening water to the speed of printing press, when the printing press is decelerated. The first and second curves being different in feeding amount of the dampening water from each other.

Abstract: A device for stacking selected sheets in an offset manner so as to facilitate print quality measurements. Certain sheets are automatically or manually selected to be offset deposited onto a stack of sheets so that an edge of the selected sheet including a number of printed measuring fields extends beyond other sheets in the stack. A measuring head transversely scans the measuring fields of the selected sheet for print quality measurements while subsequent sheets are stacked in the ordinary manner. Since subsequent sheets do not cover the extending edge of the selected sheet, sufficient time is provided to complete the scanning operation with a single measuring head without interrupting or slowing the normal stacking rate.

Abstract: A method for measuring and regulating the amount of printing ink supplied by an ink fountain roller to a vibrator roller includes passing the ink fountain roller past a measuring bar which measures ink thicknesses and angles of duration. This data is then utilized to ascertain a volume of ink transferred with this information being then compared with a pre-selected set point volume. Adjustments to the ink metering gap for each ink doctor blade can then be made so that the ink volume actually transferred will be the same as the set point value.

Abstract: Ink is picked up by an ink roller which has a surface characterized as consisting of a foamed plastic with pores open at the outer circumference but not interconnected. The ink roller dips into ink within an ink trough. The ink being applied to the ink roller is controlled by stripping elements formed as rollers which are pressed with controllable force against the surface of the ink pick-up roller; the force can be controlled, for example, by pneumatic or hydraulic fluid means, such as pressure piston-cylinder arrangements, blow-up pillows, or fluid pressure being applied against the roller mechanism directly; or by mechanical means, such as by a spring suspension in which the attachment points of the springs are selectively positionable. Preferably, the stripping rollers are about 1/15 or less of the diameter of the ink pick-up roller, and driven at a circumferential speed which is slow with respect to that of the ink pick-up roller. Ink can be transferred directly to a printing plate cylinder, or to ink transfer rollers. Both the ink pick-up roller and the stripping roller, preferably, are axially oscillating.

Abstract: To apply herbicide to weeds extending above a crop, a nylon carpet on the cylinder of a roller applicator has herbicide applied to it as a tractor or other vehicle carries it through a field. The roller is held just above the crop where it contacts weeds and is rotated in the opposite direction as the tractor. A moisture sensor is spaced from the applicator on the roller and controls a valve that applies the herbicide to the roller to maintain a preset moisture level in the roller carpet. The amount of moisture is set by experimentation to permit an adequate amount of herbicide to be applied to various weeds without causing dripping from the point of contact on the roller by the weeds.
