- the middle ring 226 is fixed on one side to the flange 216 and on the other side to the collar 206.
- the inner ring 224 is slightly eccentric with respect to the middle ring 226, of the order of 1 mm.
- the middle ring 226 and the outer ring 228 together form a sliding bearing, that is to say that the middle ring 226 is able to perform a rotation by sliding relative to the outer ring 228, this outer ring 228 being fixed to the amount 24 of the frame 4.
- the structure of the eccentric bearing 202 'located on the control side 26' of the printing unit 2 is identical to the structure of the eccentric bearing 202 which has just been described.

- the adjustment means 204 are not reproduced on the control side 26 '.
- the collar 206 has a substantially annular appearance, apart from two forks 232 and 234, one being substantially opposite the other.
- the fork 232 is secured to a deflection triangle 210 which provides coupling with the first offset device 100.
- the deflection triangle 210 is secured by the rod 106 to the collar 104 and thus to the eccentric bearing 105 of the first device
- the second offset device 200 uses the elements 104, 105 and 106 of the first offset device 100. These elements are therefore part of both offset devices at a time.
- the deflection triangle 210 consists of three vertices A, B, C connected by straight segments S1, S2, S3.

- the lever 238 is mounted on the tube 208 at the end located on the function side 26 of the printing unit 2.
- the elements connected to the lever 238', namely the rod 236 ', the collar 206 'and eccentric bearing 202' (not shown in FIG. 7) are identical reproductions of the corresponding function-side elements 26 which ensure identical spacing of the other end of the drive shaft of the blanket cylinder 14. Reproduction of the same elements of the function side 26 and the control side 26 ', connected by the tube 208, allows a homogeneous displacement on either side of the lower blanket cylinder 14.
- an operator wishes to print with a paper of a given thickness using the printing unit 2 according to the invention.
- the operator will set the distance between the lower blanket cylinder 14 and the upper blanket cylinder 10 according to the thickness of the paper to be printed by the second offset device 200 according to the invention.
- the operator will turn the rotary knob 222 by a desired angle (see Figure 4).
- This rotational movement is reproduced by the cardan shaft 220.
- the shaft 220 being only free in rotation but not in translation, its rotation will have the effect, through its threading engaged with the complementary thread of the 218 nut, to advance or retreat the nut 218, as shown in Figure 4 by the double arrow G.
- This movement G results in a pivoting of the flange 216 and thus the middle ring 226 and collar 206 (see Figure 6).
- This pivoting is transmitted through the tube 208 on the other side 26 'of the printing unit 2 and results in a corresponding pivoting of the middle ring 226' of the eccentric bearing 202 '.
- the ends 22, 22 'of the drive shaft of the lower blanket cylinder 14 being housed slightly eccentrically inside the bearings 202, 202', a pivoting of these bearings results in a slight radial displacement of the cylinder lower blanket holder 14 with respect to the upper blanket cylinder 10.
- radial displacement means a displacement of the cylinder perpendicular to its longitudinal axis, that is to say a displacement along a longitudinal axis. radius of the cylinder.
- the linking kinematics of the diverting triangles 210, 210 ' ensures a permanent contact between the lower blanket cylinder 14 and the lower plate cylinder 16 during the adjustment with the aid of the device. 200.
- the return triangles 210, 210 ' rotate exclusively around a second center of rotation C2, distinct from the first center of rotation C1 (see FIG.
- FIGS. 8 to 11 illustrate the elements situated on the function side 26 of the printing unit 2.
- the bottom plate cylinder 16 can be distinguished with its collar 104, the lower blanket cylinder 14 with its collar 206, as well as the upper blanket cylinder 10 with its collar 107.
- the upper plate cylinder is not represent.
- FIG. 8 shows the cylinders in their operational state, the first offset device 100 having not been activated and the second offset device 200 being in "mini" adjustment mode, where the distance L between the cylindrical surface 18 of the upper blanket cylinder 10 and the cylindrical surface 20 of the lower blanket cylinder 14 is substantially equal to 0 mm. It will be noted that the distance D between the cylindrical surface of the lower blanket cylinder 14 and the cylindrical surface of the lower plate cylinder 16 is also substantially equal to 0 mm.
- the term "cylindrical surface” the surface of revolution of the cylinder extending from one amount of the frame 4 to the other.
- the state shown in FIG. 9 corresponds to the state shown in FIG. 8, with the difference that the first offset device 100 has been activated. This activation causes a pivoting of the lever 118 and therefore the collars 107 and 104, which causes a spacing of the cylinders 10 and 16 relative to the cylinder 14.
- the cylinder 14 and its associated collar 206 on the other hand have not moved. From this spacing results a value of L and D of about 1.5 mm.
- FIG. 10 again shows an operational state, but in this case, the operator has actuated the offset device 200 to adjust the distance between the two blanket cylinders 10 and 14 in the "max" mode, L having then a value of about 0.3 mm.
- This setting is suitable for optimizing the print quality on thick paper.
- the collar 206 of the lower blanket cylinder 14, and with it the bearing 202 have pivoted by an angle ⁇ with respect to the position shown in FIG. 8. Thanks to the deflection triangle 210, the cylinder bottom plate 16 followed the movement of the blanket cylinder lower 14, so that the distance D is always substantially equal to 0 mm.
- Figure 11 corresponds to Figure 10, the offset device 100 having been activated.
- the distance L is then equal to about 1.5 mm, while the distance D is equal to about 1.65 mm. It can be seen that the activation of the offset device 100, when the offset device 200 is in "maximum” adjustment mode, results in a gap D between the lower blanket cylinder 14 and the lower plate cylinder 16 (see FIG. 11) which is greater than the spacing D obtained when activating the offset device 100 when the eccentric device 200 is in the "mini" adjustment mode.
- FIGS. 12 to 14 illustrate alternative embodiments of the offset device 200. In all three cases, these are representations of the elements of the function side 26.
- the variant according to FIG. 12 is different from the preferred solution previously described by the shape of the deflection triangle 210 and associated links.
- the deflection triangle 210 has substantially the shape of a boomerang with an elbow K and two branches B1 and
- the branch B2 is directly connected to the collar 104 of the lower plate cylinder 16, while the branch B1 is connected to the collar 206 of the lower blanket cylinder 14 via a link 212.
- the rod 106 is removed and the link 128 extended.
- the deflection triangle according to FIG. 13 has a shape of a continuous curve, in contrast with the reference triangle according to FIG. 12 which consists of two straight segments connected by a corner.
- the branch B2 is connected to the collar 104 via the connecting rod 106.
- the elbow K is directly connected to the collar 206.
- the eccentric bearing with three rings of the lower plate cylinder is replaced by a new four-ring eccentric bearing 108.
- a first ring 110 of this new bearing 108 is part of the first offset device 100 and is connected thereto by a rod 132.
- a second ring 214 of this new bearing 108 is part of the second offset device 200 and is connected thereto by a link 240.
- the role of the rings 110 and 214 is reversed, that is to say that the ring 110 is then part of the second offset device, while the ring 214 is part of the first device runout. It is this new four-ring bearing 108 which couples the first offset device 100 and the second offset device 200.
- a comparison of the preferred solution with that of FIGS. 12 to 14 shows that the preferred solution according to Figures 1 to 11 allows both high accuracy, ease of adjustment, easy machining, minimal space, and efforts and reduced costs.
- the offset system 5 for printing units 2 which has just been described, combining a first device 100 for offsetting the rolls with a second device 200 for adjusting the distance between the blanket cylinders, has in particular the following advantages:
