    Abstract: The present invention is directed to a method and an apparatus for applying a surface treatment composition to a photosensitive printing element during thermal processing. A photosensitive printing element is contacted with a web of absorbent material that is capable of absorbing material that is melted or softened from an imaged and exposed surface of a photosensitive printing element. The web of absorbent material is coated with a surface treatment composition to transfer the surface treatment composition from the web of absorbent material to the imaged and exposed surface of the photosensitive printing element. Applying the surface treatment composition during thermal processing provides for more complete and more uniform coverage of the surface treatment composition on the photosensitive printing element.

  • Patent number: 7169260
    Abstract: A paper or paperboard web (W) is precalendered. A web that has undergone earlier dewatering stages is calendered to attain a suitable surface for the coating process. The web is calendered (C) one-sidedly in such a manner that the absorption level of the second side (W2) of the web entering the calendering, which is higher than the absorption level of the first side (W1), is reduced in the calendering nearly to the same level or at least to the same level with the first side (W1).

  • Patent number: 6904262
    Abstract: The invention provides a double-faced image formation system that prevents transfer and adhesion of a lubricant to an image retaining conveyer and an intermediate transfer part. The system is provided with, on a return path for reversing and conveying a sheet having toner images fixed on one side thereof, a front face electrifying unit and a rear face electrifying unit. Oil adhered on the rear face of the sheet in a fixation unit by the rear face electrifying unit is electrified to a negative polarity, and the oil adhered on the rear face is made impossible to transfer to an intermediate transfer belt. The oil adhered on the front face of the sheet in the fixation unit by the front face electrifying unit is electrified to a positive polarity, and the oil adhered on the front face is made impossible to transfer to a secondary transfer conveyance belt.

  • Patent number: 6730165
    Abstract: A device for impregnating a paper web with a molten polymer to produce a paper with improved resistance to oil and grease are provided. The device includes, as part of an on-machine process, an ordinary paper web composed of cellulose or synthetic fibers, a polymer applicator, a hot reel, and a winding reel. The web, which is created through a series of processes located upstream of the subject invention, first encounters the polymer applicator, which deposits a quantity of molten polymer onto the surface of the web. The web is next transferred to a hot reel, which maintains the temperature of the molten polymer above its melting point and thereby facilitates wicking of the molten polymer into the web. After the web passes the hot reel, it is wound onto a winding reel, where additional wicking occurs until the molten polymer cools to a temperature below its melting point.

  • Patent number: 6699328
    Abstract: Temperature control of the coating medium is performed to influence the processability of coating media in an applicator system. In order to operate without losing efficiency, devices acting directly from the inside or the outside for heat supply or dissipation are connected to the elements guiding the coating medium. The temperature of the coating medium is influenced by measuring the temperature within the coating medium and, if necessary, at the elements guiding the coating medium.

  • Patent number: 6572703
    Abstract: An apparatus for forming and finishing a continuous fabric web in a single operation. The apparatus includes a fabric web forming station for forming a continuous fabric web and a finishing station downstream from the fabric web forming station for receiving the continuous fabric web from the fabric web forming station and for providing a finishing treatment to the continuous fabric web. In the preferred embodiment, the finishing station includes a substantially excess-free applicator which helps to prevent thick spots in the coated fabric web which may occur when a coating applicator is stopped and restarted. In the preferred embodiment, the finishing station includes a curing station downstream from the applicator. The curing station may include both a drying station and a heat set station downstream from the drying station. The operating temperatures of the drying and heat set stations are controlled to minimize the amount of air having VOCs to be treated before being discharged into the atmosphere.
