  • Patent number: 5887214
    Abstract: The apparatus for coating a photosensitive material (M) with a processing liquid comprises an activator coating mechanism (43) for metering a constant amount of activator to apply the metered activator to the photosensitive surface of the photosensitive material fed by the pair of introduction rollers. The activator is supplied form a plurality of discharge holes (121) bored in a pipe (122) and is once received by a receiving portion (124). The activator is diffused horizontally and flows downwardly through a plurality of openings (123) bored at the bottom of the receiving portion onto a coating roller (125). The activator is diffused again at the contact between the coating roller and a diffusion film (126) and is coated to the photosensitive material by the coating roller.

  • Patent number: 5875370
    Abstract: The present invention relates to a coating apparatus having a removable coating module for applying a protective coating to at least one surface of a photosensitive material. The coating apparatus can be a stand-alone unit and can be added to an existing or new photographic processor. The coating product can be a solution having a predetermined viscosity which is applied to at least one surface of the photosensitive material prior to drying in a manner that allows the solution to be uniformly applied to the at least one surface at a specific layer thickness. The viscous solution after drying functions as a protective coating which can protect the processed photosensitive material against scratches and moisture. The removable coating module facilitates maintenance and cleaning after the viscous solution has been consumed.

  • Patent number: 5839011
    Abstract: The apparatus for coating a lithographic printing plate or a photosensitive material (M) with a processing liquid comprises first and second pairs of feed rollers (41,42: 44,45) for feeding the photosensitive arterial along a predetermined path. A coating roller (125) is provided therebetween. Guide members (48, 49) contact the bottom surface of the photosensitive material and to guide the photosensitive material. The contacts of the guide members and the photosensitive material are at the levels higher than the coating level at which the processing liquid is applied to the photosensitive material to prevent uneven coating of the photosensitive material with the processing liquid after the trailing edge of the photosensitive material has passed the first pairs of the feed rollers (41,42).
