| 64 | Cylinder impurity remover apparatus | US09729026 | 2000-12-04 | US06457412B1 | 2002-10-01 | Phillip E. Jones |
| A removable, compact and easily accessible cylinder impurity remover apparatus has a wiping position for removing impurities from a rotatable printing plate cylinder on a printing press and a non-wiping position. The impurity remover removeably slides or swings into position for wiping a plate on the plate cylinder. Most preferably, a pressure source acts on two pistons to move two parallel reciprocably mounted shafts and a wiper blade mounted thereon to the wiping position. Both the pistons and shafts are preferably contained inside an actuator bar, which is mounted parallel to a printing plate cylinder. As the wiper blade moves forward to the wiping position, a bias member is compressed and remains compressed until the pressure source stops, allowing the bias member to automatically retract the reciprocably mounted shafts and wiper blade to a non-wiping position. According to one embodiment of the invention, the actuator bar is mounted on the top side of a primary support bar having a shaped track to permit a sliding movement into and out of the printing press. According to a second embodiment of the invention, the actuator bar is pivotally connected to a first main side support and the opposing end of the actuator bar is receivable in a docking portion of a second main side support for pivoting movement relative to the printing press. Both embodiments are compact and allow for the operator to easily access the wiper blade for maintenance and cleaning. | ||||||

| An improved apparatus and method for cleaning one or more of the rollers used in printing presses. Typically, the printing press features manual or automated devices for supplying cleaning solvent to the press during a washing operation. A blade assembly is pivotally disposed for engagement with the press roller. The blade assembly features a blade unit for scraping solid and liquid debris from the roller, and a receptacle trough for collecting used solvent as well as solid and liquid debris. In the improvement, a sheathing system is provided to supply protective sheath material to cover the blade assembly to keep the blade assembly clean during the washing operation. The sheath material preferably has a low coefficient of friction to prevent wearing of the components and is relatively thin to maintain the blade geometry for effective cleaning of the roller. An absorbent lining is disposed in the receptacle trough to absorb the used ink and solvent and to protect the trough from soiling during the washing operation. The sheathing system is automatically actuated either upon the pivoting engagement of the blade assembly with the press roller or when the blade assembly is pivoted away from the press roller. | ||||||

| 71 | Method and apparatus for cleaning a roller surface | US571824 | 1996-02-06 | US5644986A | 1997-07-08 | Erik Gydesen |
| Disclosed is a method and apparatus for cleaning a cylinder surface. The method is particularly suitable for use on flexographic printing cylinders where the automatic cleaning apparatus facilitates the cleaning of plate cylinders or on any type of cylinders. The method comprises detaching particles such as dust, fibers and other foreign objects deposited on the cylinder surface by means of pressurized fluid of air, liquid, ultrasound or other suitable media. After the particles have been detached, the cylinder surface is exposed to a vacuum unit whereby the detached particles and other material deriving from the cleaning medium are sucked off the surface of the cylinder. The advantage is that, in many cases, it will not be necessary to halt the printing process for cleaning the cylinder. The apparatus comprises a cleaning head or pipes capable of providing the pressurized fluid to the cylinder surface and removing any particles detached from the cylinder surface while the cylinder is in normal operation. | ||||||

| 78 | Press dampening system | US940686 | 1992-09-04 | US5218903A | 1993-06-15 | Edward P. MacConnell; Robert King; Donald L. Frank |
| A dampening system has a pan for containing dampening fluid, and transfer and metering rollers for bringing dampening fluid up out of the pan. A transition roller contacts one of the transfer and metering rollers. The transition roller is movable between first and second positions. In the first position, the transition is off of the plate cylinder and dampening fluid is applied to the plate cylinder by ink form rollers. In the second position, the transition roller is on the plate cylinder. Another version of the dampening system has a bridge roller between the transition roller and a ink form roller, which bridge roller is movable between third and fourth positions. In the third position, the bridge roller is on the transition roller. In the fourth position, the bridge roller is off of the transition roller. The dampening system can dampen the plate cylinder without the use of alcohol. The transition roller is rotated by a separate motor so that its speed is controlled independently of the other rollers. When the transition roller is on the plate cylinder, it can be slowed down to clean hickeys off of the plate cylinder. When the plate cylinder is clean, it can be moved off of the plate cylinder or speeded up to the same speed as the plate cylinder. A controller is provided to automatically adjust the amount of dampening fluid being applied to the plate cylinder by regulating the speed of the transfer and metering rollers. | ||||||
