What is contemplated is a printing cylinder washer having a removable or portable drive assembly, or a series of portable drive assemblies of different lengths to accommodate different sizes of print rollers. The drive assemblies have a drive mechanism enabled by a dynamic flow of cleaning solution within the washer reservoir. What is also contemplated is the use of an elevation system, an agitation platform, under-immersion spray bars, an ultrasonic wave cleaning system, and a hatch or door equipped with a thermal breaker in conjunction with the hydro-driven portable drive assembly. What is also contemplated is a method of washing printing rollers within the above-described printing cylinder washer by aligning a nozzle with the drive assembly. |

Detachable inking device for a flexographic printing machine, its embodiment, cleaning and use in such a machine. This device comprises a chambered doctor blade (9) mounted on two lever-supports (13, 14) crossed by duct joining pieces (15, 16) respectively. The lever-supports are rigidly attached to a shaft (11) about which they are pivotable and which is held between the frames (34) of said flexographic printing machine. Said chambered doctor blade (9) consists of a body (25) made of light metal material, crossed at one of its ends by a tube (26) emgerging from the bottom (28) of said body (25), and at the other end by a tube (40) having its opening part (29) at level with the bottom (28) of the body (25). The latter rests on seals (38, 39) secured to the lever-supports (13, 14) to which are attached centering and fixing means (17, 18) allowing a quick loosening of the chambered doctor blade (9) without the help of any tool. The body (25) comprises two plane and outwardly slanted projecting parts against which are glued two doctor blades (19, 20) by means of a gluing means (48). The doctor blades (19, 20) are also held at their ends by a supporting piece (21) having two supporting parts (35, 36) applying the ends of the doctor blades (19, 20) on an end seal (22). Said chambered doctor blade (9) can be handled by a manipulator (55) and conveyed into an automatic washing device (80) or a device (100) for gluing and ungluing said doctor blades (19, 20). |

A system particularly adapted for cleaning ink residue from cells forming part of an outer surface of a ceramic inking roll of a printing press roller assembly includes an ultrasonic tank unit. Seated on an top open end of the tank unit is a drive mechanism comprising a set of spaced apart wheels operatively connected to a motor by a belt. As fitted over the wheels, the belt engages one end of a shaft of the ink roller assembly. An opposite end of the shaft then is held by a set of wheels of an idle mechanism also seated on the tank unit top end. For use the tank unit is filled with a cleaning solution so that about a bottom one-third of the roll outer surface submerges in the solution, and the shaft and any included bearings or gears on the shaft remain free from contact with the solution. As the motor drives the belt to slowly turn the roll through the cleaning solution, sonic energy from a generator in the tank unit forces solution into the roll cells to incrementally scrub out the imbedded ink residue. As residue is removed, the surface of the roll changes from a shinny-dark to a uniform dull-light appearance indicating that cleaning is complete. |

A process and apparatus for carrying out the ultrasonic cleaning of a printing cylinder including a cleaning tank, which contains a liquid cleaning detergent into which the printing cylinder to be cleaned is immersed. Heaters are also included for heating and maintaining the temperature of the cleaning liquid at a temperature below 185.degree. F., preferably within the range of 130.degree.-160.degree. F. while the printing cylinder is cleaned. The cleaning of the printing cylinder within the cleaning tank of the apparatus is carried out by ultrasonic waves which are generated and radiated throughout the cleaning liquid for a period of time, generally, between 5-30 minutes. In a preferred embodiment of the apparatus and process, the printing cylinder is continually rotated within the cleaning tank during the period of time when the ultrasonic waves are radiating through the cleaning liquid. |

A washing machine for a printing or processing table including an arrangement of two complementary carriages, each one of which rests on a lateral rail provided along opposite sides of the table for the tracking of the carriages. The carriages are solidly fixed to each other by means of a bridge element comprised of two telescopically arranged tubular bodies which are provided with adjustment and fixing means capable of securing the coupling of the tubular bodies to any relative dimension between two points, one of which is of maximum approximation while the other is of maximum separation. Each one of the carriages is provided with a cantilever arm directed inwardly of the table, which arms are longer than half the width of the table and support a plurality of circular brushes, each of the brushes being provided with a gear. The brushes are arranged in a zig-zag configuration and are suspended from pneumatic pistons the path of travel of which is greater than the distance which separates the brushes from the table and the pressure of which is limited by the action of a regulating valve. The telescopic tubes of the bridge are connected by a spindle and fixed nut device. |
