Abstract: A method of, and an apparatus for, cleaning a web of photo film during the manufacture is disclosed wherein the web of photo film is transported in its lengthwise direction, and a cleaning tape made of felt is pressed onto an entire area or a side portion of a surface of the photo film or a side edge of the photo film, while the photo film and the cleaning tape are transported in opposite directions.

Abstract: An apparatus and method for removing material from an elongated member having known dimensions and traveling through known air densities, in which applied compressed air removes the material from the elongated member in a chamber configured to optimize the decompression and acceleration of the air.

Abstract: An embossing roll cleaning apparatus is provided. The cleaning apparatus includes a nozzle having an air inlet and an elongated narrow outlet that extends an embossing width of the embossing roll. A source of compressed air is connected to the air inlet of the nozzle. The outlet of the nozzle directs the pressured air as an air knife against the surface of the embossing roll to dislodge deposits stuck to the surface of the embossing roll.

Abstract: The device sprays a mist of cleaning fluid onto the record medium—e.g., motion picture film—and wipes it off, preferably with a soft material such as velvet. Then, the film is dried with air, including thin air jets to spread the liquid evenly, and heated, ionized air. The device has a closed housing and air in the housing is evacuated and sent to a still to recover much of the cleaning liquid and prevent its escape into the atmosphere.

Abstract: A method of cleaning tissue webs in a rewinder utilize the Coanda effect to produce an improved tissue product. The Coanda effect web cleaner utilizes the smooth flow of a thin layer of air to scrub off dust and lint embedded and entangled in the web surface while stabilizing the web in its travel. Two of these Coanda effect web cleaners arranged on opposite sides of a multiple-ply web in a rewinder are effective when operated according to the method of the invention to produce a rewound tissue with an unexpectedly low loose dust and lint count on its surfaces.

Abstract: A track assembly allows the placement of a pair of web cleaning devices on either side of a paper web moving upwardly through the floor of a press. The track assembly facilitates mounting and rapid removal of web cleaning buffs from beneath a press. A docking plate is installed on the operator side of the press, and a pivotally mounted flip plate is installed on the drive side of the press. A pair of tracks are mounted on either side of the web slot and extend between the docking plate and the flip plate. The tracks inter-fit with the docking plate and are clamped to the flip plate. A removable ramp can be temporarily attached to the drive side of the tracks to allow the cleaning assemblies to be moved up the ramp and positioned on each of the tracks.

Abstract: In a web cleaning and destaticizing apparatus, an upper surface of a front edge is shaped into a curve with a large radius of curvature so that a cleaning solution applied onto a surface of a web W can be smoothed. An upper surface of a doctor blade is shaped into a curve with a small radius of curvature so that a great part of the cleaning solution SOL1 smoothed by the upper surface of the front edge can be scraped off into a front slit 24. An upper surface of a back edge 23 is formed so that an undercoat solution can be applied onto the surface of the web just after the great part of the cleaning solution is scraped off by the upper surface of the doctor blade 22. Accordingly, the allowable range of web incident angle can be widened by the front edge, so that not only the cleaning solution can be scraped off by the doctor blade without scattering in the surrounding directions but also static electricity accumulated can be eliminated rapidly and efficiently by the undercoat solution.
