    摘要: The apparatus comprises a housing (12) defining one or more treatment cells (14, 16, 18) having a sheet material path (20) extending therethrough from an entrance (22) to an exit (24). The entrance (22) and exit (24) are each closed by a respective drive roller (26) in contact with a reaction surface (28, 50) to define a nip (29) therebetween through which said sheet material path (20) extends. Rotatable sealing means (30) seal each drive roller (26) to said housing (12). A reduced pressure is established within said treatment cell (14, 16, 18). The continuous treatment of sheet materials can be carried out under reduced pressure, in a convenient and reliable manner.

    摘要: The present invention provides an apparatus for developing monosheet lithographic offset printing plates according to a DTR process, wherein the guidance control of a printing plate in a developing bath, is characterised by

    1) a pair of entrance rollers 21 that are disposed at the entrance of the developing station 12, one above the other and substantially parallel under an angle α of at least 5° to the horizontal, and
    2) a pair of exit rollers 22 that are disposed substantially parallel, under an angle γ to the horizontal less than 25°, at a distance from the pair of entrance rollers 21 so that the printing plate is guided through the developing station by any or both of the roller pairs 21 or 22, and
    3) a bottom guidance member 19 for supporting the printing plate, that has a curvature radius of at least 400 mm, and an exit plane inclined upwardly for guiding the printing plate in a well defined path in the developing bath 12, such that the leading edge of the plate is directed tangentially into the nip of said pair of exit rollers 22, defined by an angle β to the horizontal, said angle being less than 25° and wherein said bottom guidance member (19) has an open mesh structure.
