| 29 | Rotary printing plate washing apparatus | US558692 | 1990-07-26 | US5067193A | 1991-11-26 | Daniel J. Thomas |
| The apparatus includes an elongate housing containing a rotatable plate-mounting drum, a reversibly rotatable brush roll, and first and second spray manifolds for respectively spraying fresh water and recirculated water onto the printing plates. The plate-mounting drum may be formed of perforate metal so as to facilitate mounting printing plates thereon. When the printing plate or plates to be cleaned extend longitudinally along only part of the plate-mounting drum, valves associated with the manifolds may be closed to cause water to be discharged only from those manifold sections that confront the printing plates. The fresh water supply circuitry of the apparatus is separate from the circuit for the recirculated water circuitry. A limit switch associated with a housing cover of the apparatus prevents discharge of water from the spray manifolds when the cover is not fully closed. Passive piston and cylinder assemblies assist in movement of the cover portion of the housing from its closed position to an open position, and prevent overly abrupt movement of the cover portion from its open position to its closed position. The spray patterns emitted by laterally adjacent nozzles of the spray manifolds are inclined such that edge portions of laterally adjacent ones of the spray patterns are disposed in overlapping but non-impinging relationship to each other. The spray manifolds are mounted within a pivotally movable housing cover of the apparatus, so as to be readily accessible for purposes of cleaning and/or repair. | ||||||

| 33 | Printing screen cleaner | US3580261D | 1969-05-12 | US3580261A | 1971-05-25 | KEY JOHN W |
| Printing screens are carried through a tunnel by an overhead conveyor. In an enlarged central section of the tunnel are opposed rows of spray heads to direct a cleaning solvent at the screens under pressure. A solvent with material removed from the screens drains into a removable separating tray to extract at least a portion of the material from the solvent. The solvent then drains into a sump from which it is pumped back to the spray heads. At opposite ends of the central cleaning section are entrance and exit sections having doors which are pushed aside by the screen as it is moved through the tunnel. A fan draws air in from the ends of the tunnel and discharges it out a stack. Fire quenching means has spray heads in the tunnel.
