161 Cleaning apparatus for web offset printing press US57326 1998-04-08 US5868073A 1999-02-09 Toshihiko Ebina
A cleaning apparatus for a rotary printing press includes a cleaning blade, a cleaning cloth, and a cleaning unit and air cylinders, or an air cylinder, a guide shift mechanism, and a cleaning cloth travel mechanism. The cleaning blade has a distal end portion which abuts against the circumferential surface of an oscillating roller during a cleaning operation to scrape a waste ink, and a rear surface continuous to the distal end portion to guide the scraped waste ink downward. The cleaning cloth travels during the cleaning operation done by the cleaning blade to collect the waste ink scraped by the cleaning blade. The cleaning unit and air cylinders, or the air cylinder, the guide shift mechanism, and the cleaning cloth travel mechanism bring the cleaning cloth into contact with the rear surface of the cleaning blade, when the distal end portion of the cleaning blade is in contact with the circumferential surface of the oscillating roller, to collect the waste ink on the cleaning blade.

169 Container body inking apparatus US892891 1992-06-03 US5249524A 1993-10-05 Edwin C. Morris, deceased
An apparatus for applying ink to a printing plate which utilizes a plurality of successive, interconnected/interfacing rollers to provide a desired film thickness of ink to the printing plate such that a desired design may be transferred to a container body. In one embodiment, two transfer rollers directly engage the cylinder upon which the printing plate is positioned. The orientation of these rollers may be adjusted in a manner to enhance the distribution of ink to the printing plate. Advantageously, this adjustment does not require the positioning of any components within the roller body area (e.g., an area through which ink propelled away from the rollers would travel). In order to further enhance the distribution of ink, at least one of the rollers of the inker oscillates to alternately engage two adjacently positioned rollers. This oscillation is also provided without requiring components within the defined roller body area.
170 Printing press wash-up system US815381 1991-12-31 US5224424A 1993-07-06 Jon L. Layland
A printing press wash-up system is disclosed comprising a fluid receptacle arrangement, a mounting assembly, a wiper assembly, and a pivoting arrangement. The fluid receptacle arrangement is constructed and arranged to operably receive fluid from a printing press roller when it is mounted to the printing press by means of the mounting assembly. The wiper assembly selectively removes fluid from the printing press rollers in operable association with the fluid receptacle arrangement to direct fluid from the roller to the fluid receptacle arrangement. The pivoting arrangement selectively pivots the fluid receptacle arrangement between a first and second extreme position, the first extreme position occurring when the fluid receptacle arrangement is operably positioned to selectively receive fluid from the printing press roller and the second extreme position occurring when the fluid receptacle arrangement is positioned such that it cannot selectively receive fluid from the printing press roller. The pivoting arrangement allows the fluid receptacle arrangement to be readily cleaned out after a cleansing operation has been completed. In addition, the pivoting arrangement allows a person to readily gain access to the printing press rollers without having to remove the fluid receptacle arrangement from the printing press.

Exemplary processes include printing, coating, and painting.
172 Easy-to-clean inking mechanism for a printing press US828739 1986-02-12 US4643092A 1987-02-17 Kenich Yamagishi; Katsuyuki Mori
A printing press inking mechanism comprising a fountain roller dipped in a printing ink in an ink fountain, and a drawout roller movable alternately into and out of rolling engagement with the fountain roller and a first of a series of ink rollers for ink transfer from the former to the latter and then to a plate cylinder. The drawout roller when in rolling engagement with the first of the ink rollers can be revolved therewith and so can be automatically cleaned therewith clean of the printing ink by a solvent. The fountain roller has so far been left out of rotation, requiring manual cleaning. Thus a cleaning roller is additionally provided which is movable, at the time of the cleaning of the rollers, into rolling engagement with both the fountain roller and the drawout roller to transmit the rotation of the ink rollers to the fountain roller, so that the fountain roller can also be automatically cleaned with the other rollers.

177 Lithographic printing apparatus and wash-up device US31772372 1972-12-22 US3842735A 1974-10-22 SOUTHAM D; GAFFNEY J
Lithographic dampener has a hydrophilic roller for supplying dampening solution to a resilient dampener form roller capable of carrying ink and dampening solution. The dampener form roller is driven primarily by surface contact from the printing plate when in printing position, and driven solely by surface contact with a driven rider roller when in non-printing position. The rider roller is always maintained in contact with the dampener form roller during normal press operation, in both printing and nonprinting positions. An ink form roller of the inking system has three positions: a printing position, a first throw-off position, and a second throw-off or ''''wash-up'''' position wherein it contacts the rider roller of the dampener when the latter is in its non-printing position, whereby cleaning solution applied to the rolls of the inker is also transmitted to the dampener form roller for simultaneously cleaning the inked rollers of both the inker and dampener.
