Definitions

  • the rear extreme parts of the two shafts 9 and 10 are respectively secured to two pinions 18 and 19, of the same pitch diameter, engaged with one another.
  • one of the pinions 18,19 in turn engages a drive pinion, not shown, which is rotatably mounted on the frame 1 of the printing apparatus and which is rotated by a general control device of the apparatus. Therefore the two plate cylinders 4 and blanket 5 are rotated in opposite directions to each other, at the same peripheral speed.
  • the front bearing 12 comprises a cylindrical bearing 12a passing through a corresponding opening 22 in the front flange 7 and a flange 12b fixed to one end of the bearing 12a, by means of screws 12c, and applied against the internal face of the front flange 7.
  • This front bearing 12 (FIG. 4) is mounted horizontally adjustable in the opening 22 provided in the upper part of the front flange 7 of the cassette in order to allow a slight bias between the shafts 9 and 10 to be adjusted as desired.
  • opening 22 has a diameter slightly greater than the external diameter of the bearing 12a of the front bearing 12 so that this bearing 12 is housed with a certain horizontal clearance in this opening 22.
  • the front bearing 12 is held by three support points.
  • a first upper support point A is constituted by the upper point of tangency between the cylindrical bearing 12a of the bearing 12, which is located in the opening 22 of the flange 7, and the upper part of this circular opening 22.
  • a second point support B located on the left side of the plane P passing through the axis of the bearing 12 and through the axis of the bearing 14 and at the left end of the diameter d of the bearing 12 which is perpendicular to the plane P, is defined by the contact point of a spherical stop 23 applied against the edge of the flange 12b by a bias adjustment screw 23a whose axis intersects the axis of the bearing 12 and which is screwed in the left part of the flange 7, in a support 24 fixed to this flange.
  • the other fulcrum, located on the right side of the bearing, is part of a device 39 playing both the role of bearing retainer and anti-jamming device.
  • This device 39 is provided, on each of the flanges 7 and 8, opposite the shoe 37, for example at the location of the right end of the horizontal diameter d1. However, the device 39 could also be located a little lower in the lower right quadrant.
  • This device 39 comprises a locking finger 41 with a rounded end and which is engaged in a notch 42 formed in the peripheral surface of the flange 15b of the bearing 15, at the location of the right end of the horizontal diameter d1.
  • the flanges 14b, 15b of the front 14 and rear 15 bearings of the blanket cylinder 5 carry, at their lower parts, inserts 46, fixed by means of screws 47 and projecting towards the bottom relative to the peripheral surface of the flanges 14b, 15b.
  • inserts 46 are intended to constitute lateral stops coming into contact, when the device is in the printing position, with adjustable stops, not shown, forming part of the movable assembly of the counterpart cylinder 11, and serving to define the crushing of the sheet between the blanket and the counter cylinder.
