Abstract: A drying apparatus and method utilizes the combination of radiant heat and air to quickly dry photosensitive material. The arrangement of the drying apparatus is such that radiant heat is first applied to photosensitive material at a radiant heat application section to substantially dry the photosensitive material without emulsion side contact and, thereafter, an air flow is directed onto both sides of the photosensitive material after it leaves the radiant heat application section. A plurality of air flow nozzles are used to direct the air onto the photosensitive material with the nozzles being oriented so as to direct air away from the radiant heat application section of the drying apparatus. This provides for an efficient and quick drying of photosensitive material in a compact unit.

Abstract: A combination infrared/convection dryer or oven for drying travelling webs. A shutter assembly is provided between the infrared radiation source and the moving web in order to selectively expose the web to infrared radiation. Drying efficiency is optimized by adding heated impinged air at high velocity on the machine direction ends and between the infrared elements. The air being discharged on the web is heated as it is pulled across the elements to a centralized return air duct. The return air is pulled into the inlet of a close coupled supply fan which then discharges the air to the nozzles. A portion of the air is also exhausted to atmosphere to maintain the oven enclosure in a negative pressure state, thus drawing fresh make-up air into the oven housing through the web inlet and outlet slots. Flotation nozzles can be used where contactless support of the running web is desired. Enhanced drying of the web and/or a coating on the web at high speed is achieved without a concomitant increase in dryer length.

Abstract: A drying apparatus and method utilizes radiant heat and forced air to provide for rapid drying of photosensitive material without emulsion side contact. The forced air is supplied through air passages formed between cover members that partially surround radiant heating bars, and is directed onto the photosensitive material where it impinges upon the photosensitive material. As the air passes through the air passages, it is heated by radiant heat from the heating bars. The heated air increases the drying effect of the drying apparatus and at the same time, impinges on the photosensitive material in a manner which assists in holding the photosensitive material firmly against, for example, drive rollers.

The first cooling section has a curved shape such that the imaging material is curved when riding on and being cooled by the first cooling section.

Abstract: A method and apparatus for coating and drying coated substrates without introducing significant surface imperfections while running at higher web speeds than known drying methods. The substrate is preferably coated within the drying enclosure or the coating bead may form a closure at the entrance of the drying enclosure. The substrate is moved through a first drying enclosure along a first axis. The first drying enclosure is substantially isolated from an external environment. A first low velocity, substantially laminar flow field of a drying gas is directed across the front surface of the substrate. The first flow field is generally parallel to the front surface and generally perpendicular to the first axis to minimize the formation of surface imperfections during the evaporation of the coating solvent. The substrate may then be moved to subsequent drying enclosures through transition enclosures that minimize surface imperfections due to high velocity interaction between the adjacent drying enclosures.

Abstract: Drying a coated substrate which includes magnetic particles includes a condensing surface spaced from the substrate. This creates a longitudinal gap between the substrate and the condensing surface. Liquid is evaporated from the substrate to create a vapor and the vapor is transported to the condensing surface without requiring applied convection. The vapor is condensed on the condensing surface to create a condensate which is removed from the condensing surface. Removal is performed, using more than gravity, without allowing non-uniformities of the condensate film to occur. The magnetic particles are oriented on the coated substrate by subjecting the coated substrate to a magnetic field created at a location outside of the dryer space.

Abstract: An infra-red dryer utilizes high velocity air jets which scrub and break up the moist air layer which clings to the surface of a freshly printed and/or coated sheet. The high velocity air jets are directed through multiple air flow apertures across an array of infra-red lamps onto the freshly printed and/or coated sheets. An extractor exhausts the moisture-laden air from an exposure zone while short wave infra-red radiation heats the ink and/or protective coating. The effective exposure to pressurized air is increased by the air jets which produce a balanced pressure air blanket along the sheet travel path. The moist air layer is displaced from the printed and/or coated sheet and is extracted from the press as the sheet moves through the exposure zone.

Under the preferred post-drying conditions, bonding of the previously wet paper fibers takes place to lock in the desirable printing characteristics and to prevent heat roughening on the offset press.

Abstract: A method for drying photographic materials from an initial moisture content to a desired final moisture content is provided. At least one side of a photographic material having an initial moisture content is heated, with a first heater stage, to achieve an intermediate moisture content in the material. The intermediate moisture content is less than the initial moisture content of the material and greater than the desired final moisture content. The intermediate moisture content of the material is measured and an output signal corresponding to the intermediate moisture content is provided to a control means. The material is then heated with a second heater stage to the desired final moisture content. The second stage heating is controlled using the output signal and the desired final moisture content.
