    Abstract: A doctor blade system utilizes a lightweight doctor blade chamber to apply ink to an inking roller. The doctor blade chamber is removably positioned on a support plate which is, in turn, carried by linear guides on pivotable end plates. A rigid box beam is also attached to the end plates and is spaced from the support plate. A plurality of membrane cylinders are mounted on the rigid box beam and engage a surface of the support plate opposite to the surface that supports the doctor blade chamber. Through the application of suitable force, the support plate and its supported doctor blade chamber can be moved, by sliding motion on the linear slides, into uniform engagement with the surface of the ink roller. The system uses pivotable end plates which are supported by exterior plates that are, in turn, pivotably supported by press side frames.

  • Publication number: 20080245246
    Abstract: There is described an apparatus (1) for coating a cylinder (C), in particular a wiping cylinder of an intaglio printing press, with a plastic composition comprising inter alia a blade mechanism (4) comprising a single substantially planar blade (40) with a straight edge (40a) extending along the full length of the cylinder to be coated and which is mounted rotatably about an axis parallel to the axis of rotation of the cylinder to be coated. The blade comprises, at its terminal end proximate to the cylinder, an inclined end portion (4a) having an inverted-V shape rising from the upper side of the blade, the top edge of the inclined end portion forming the straight edge of the blade. The blade is adapted to be rotated so that the straight edge of the blade undergoes an upward movement substantially tangential to the periphery of the cylinder in order to discontinue the application of the plastic composition onto the surface of the cylinder.
