  • Patent number: 4527476
    Abstract: An improvement in printing presses in which at least one inking roller is placed in rolling contact with two other rollers, one of which is a slide table, this inking roller being mounted pivotally about the axis of rotation of the slide table. The inking roller (4, 5) is mounted rotatably about a shaft (15), the corresponding slide table (3) is supported by two fixed bearings (18, 19) each comprising a cylindrical outer face (20, 21), each end (22, 23) of the shaft (15) of the inking roller (4, 5) is connected to each corresponding fixed bearing (18, 19) through the intermediary of a flexible metal band (28, 29) bent in U shape, the central region of which partly surrounds the cylindrical face of the fixed bearing, being fixed thereto, and the two ends of which are fixed to the ends (22, 23) of the shaft (15) of the inking roller.

  • Patent number: 4481883
    Abstract: A low-blade type inking mechanism, comprising an ink duct roller (1) and an ink duct (4) carrying at least one detachable trough (7). The ink duct (4) is mounted on an axis (3) parallel to the axis of the roller (1) and rotatable about the latter so that the ink duct (4) can pivot about the roller (1) without the through (7) moving away from said roller (1), and pivot about the axis (3) on which it is mounted so that the trough (7) moves away from said roller (1). The mechanism is used in rotary printing presses, particularly for color printing.
