  • Patent number: 7225560
    Abstract: A system for curing printing plates with controlled radiant energy sources. A conveyor moves a printing plate through a chamber having energy radiators above and below the conveyor. Power to the radiators is controlled for each radiator or to groups of radiators defining radiation zones. Curing time may be controlled by adjusting power to the radiators and adjusting the conveyor speed. Sensors detect a plate as it enters and exits the chamber. Heat sensors may detect chamber or plate temperatures. A color sensor may detect plate color as an indicator of degree of curing. A computer system stores curing scenarios and uses the sensor signals and operator inputs to control power to the radiators and conveyor speed to provide uniform curing of the plate.

    Abstract: A dryer is disclosed in a compact design for interstation use on printing presses, particularly lithographic presses. High velocity air is combined with intense infrared radiation to heat, evaporate and scrub vapor from freshly printed substrates. Air under pressure is provided through passages in a housing which is passed toward and by the infrared lamp in such a way as to cool the lamp and thereafter impact the substrate being dried. A pressure sensing control prevents operation of the lamp without the cooling air. The lamp power circuit is switched off if air pressure is lost. The dryer is mounted in an extractor housing provided with a negative pressure to extract the supplied air after it impacts upon the substrate.

    Abstract: A combination infrared/air convection dryer or oven for 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, and to create a sealed air chamber when in the closed position. Enhanced drying of the web and/or a coating on the web at high speed is achieved without a concomitant increase in dryer length. When the drying atmosphere has a high concentration of solvent, exposure of that atmosphere to the heating elements, which can cause explosions, is eliminated by actuation of the shutters. In a preferred embodiment of the invention, air bars are used to floatingly support the moving web to avoid contact of the web with dryer elements.

  • Patent number: 5966835
    Abstract: A web to be heat-treated bears against a rotary cylinder containing a stationary complement of IR burner modules in an assembly that is axially removable from the cylinder. The IR burner complement extends all along--but only partway around--the cylinder, leaving an arcuate gap. An exhaust manifold in the gap has a configuration that precludes localized accumulation of high-temperature exhaust. The cylinder is heated primarily by radiant transfer from the IR burner modules and from heat shields, which fill any arcuate spaces not occupied by either the exhaust manifold or the IR burners. The arcuate extent of the IR burners is proportioned for developing prescribed heat output when the air/fuel mixture is supplied at maximum rate. The cylinder heat output may be reduced over a wide range, notably when the cylinder speed is adjusted during start-up and slow-down of operations. The IR burner modules heat annular bands around the cylinder to develop a temperature profile along the cylinder, i.e., across the web.

  • Patent number: 5867920
    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.

In view of the fact that one pit or the other pit of pits in the form of a pair is blocked with the torus 1 in felled wood to cause poor removal of water in cells, it is intended to prevent the blockage of the pit membrane, i.e., to break the pit membrane per se, thereby facilitating easy escapement of water in cells after the breaking. In the present invention, wood fuel is burned, and subject wood is allowed to stand in a treatment chamber filled with smoky wood gas generated by the combustion for a predetermined period of time, to expose the subject wood to far-infrared radiation and components contained in the wood gas.
