Abstract: A method and apparatus for adjusting skew settings in a dampener in a printing press. One or more skew adjustment linkages connect skew adjustment rods for the upper and lower dampeners of each printing unit. The linkage ensures that a single movement by the operator will allow adjustment of the skewing of both the upper and lower dampeners at the same time. The linkage or linkages are preferably connected at one end to skew adjustment brackets, which in turn are connected to a skew adjustment rod for one of the upper or lower dampeners. The skew adjustment rod adjusts the amount of skew of associated pan rolls. Movement of the linkage may be controlled by movement of a spring plunger, which is connected to the linkage or linkages. The spring plunger may be spring biased, and may be adjusted and locked into different skew setting positions using a pinhole arrangement.

Abstract: An additive is dispersed in a matrix having a larger thermal expansion coefficient, which forms a film that prevents the permeation of the ink at the room temperature while allowing the permeation of the ink at high temperature. An ink roller is formed by covering a roller-like sponge body containing ink (an ink holder) with the film. Along the outer circumference of the ink roller, a thermal head that heats the surface of the ink roller according to a print pattern and a platen roller that sandwiches recording sheet between itself and the ink roller are disposed. Then, by rotating the ink roller and heating the thermal head, the ink permeates through the heated part of the film and is transferred to the recording sheet to form an ink image on the recording sheet.

Abstract: A guide blade for guiding sheets in a printing machine in in-line or perfecting mode processes employing trailing edge turning, the guide blade has a front edge and an end piece, and air nozzels located in a flow surface extending from the front edge along the end piece. The air nozzels are connected to a source of pressurized gas, and direct pressurized gas in the direction of travel of the sheets. A plurality of parallel, spaced-apart, guiding fins project downwardly from the flow surface. The guiding fins have downstream ends which are spaced further away from the flow surface than the upstream ends thereof. The sheet, along with the guiding fins and the flow surface, create a diverging flow channel below the end piece of the guide blade, inducing a partial vacuum in the flow channel, which maintains the sheet in contact with said guide blade. The guide fins include air nozzels and the angle between the guiding fins and the flow surface can be adjusted.

Abstract: An apparatus and method which reduces solid mottling in an offset printing press. One or more form rolls having a hard elastomeric outer surface, in the range of approximately 50-100 Shore A durometer hardness, preferably approximately 60-90 Shore A durometer hardness, are used to transfer ink to the plate cylinder. The use of a form roll of this type ensures a smoother application of ink to the plate cylinder, which in turn ensures smoother ink application to the blanket cylinder and printed web. If more than one form roll is used, it is preferable that, at a minimum, the final form roll, i.e., the last form roll the plate cylinder contacts in the direction of rotation, be a hard elastomeric form roll. In another aspect of the present invention, the form rolls can be made of a convex shape along their axial length, such that the diameter of the form rolls at their axial center is larger than the diameter of the form rolls at their axial ends.

Abstract: An engraving head that includes a movement mechanism for moving an engraving stylus within the body housing of the engraving apparatus is provided. The movement of the engraving stylus causes the tip of the engraving stylus to approach and recede from an engraving surface. The movement mechanism contains a movable body and a first energizing means. The movable body moves in association with a movement space member's inner circumference. The movement space member is positioned inside the body housing. The first energizing means is employed to energize the movable body in a direction away from the engraving surface. Additionally, a second energizing means serves to energize the movable body in a direction towards the engraving surface against the opposing energizing force of the first energizing means. The second energizing means may be, for example, compressed gas. As the movable body travels downward towards the engraving surface, the tip portion of the engraving stylus also approaches the engraving surface.

Abstract: An image recording apparatus, having a recording head and a pair of transport rollers in front of the recording head and another pair of transport rollers behind the recording head, with a larger transport speed for a recording sheet in the latter pair for applying a suitable tension on the recording sheet, is capable of detecting the remaining amount of the sheet in front of the first pair and varying the transport speed and/or the recording area of the recording head after the rear end of the sheet leaves the first paired roller. Consequently, a potential error in record position, resulting from sheet advancement by the second paired rollers only, can be compensated. In this manner the area of precise image recording on the sheet can be expanded.
