Printing module of the flexo printing type, provided with an anilox roller (16) and an impression roller (18) which are set up between two frame parts (12, 14). Further, the printing module comprises a plate cylinder assembly (20) which is receivable in a plate cylinder holder assembly (30, 32). The plate cylinder holder assembly is provided with a plate-shaped body part (34) with a supporting ring support surface (36) with a special curve (C) which is symmetrical with respect to a curve plane. Further, each plate cylinder holder assembly comprises a body part assist assembly via which the body part is connected with the associated frame part, wherein the body part assist assembly is configured for pivoting the body part about a first imaginary pivoting axis and for pivoting the body part about a second imaginary pivoting axis, such as to allow a substantially independent distance setting between the plate cylinder and the anilox roller on one side and between the plate cylinder and the impression roller on the other side. |

1. A printing module provided with:
a frame which comprises two opposite frame parts; an anilox roller which is bearing-mounted in the frame in a manner rotatable about an anilox roller axis and extends between the two opposite frame parts; an impression roller which is bearing-mounted in the frame in a manner rotatable about an impression roller axis and extends between the two opposite frame parts; a plate cylinder assembly comprising:
a stationary shaft;two supporting rings which are each connected with the shaft near an associated end of the shaft; anda plate cylinder which is mounted on the shaft in a manner rotatable about a plate cylinder axis, the diameter of the plate cylinder substantially corresponding to the diameter of the supporting rings; a first and a second plate cylinder holder assembly which are each connected with an associated frame part, and which are each configured for removably placing and fixing therein a supporting ring of the plate cylinder assembly; wherein each plate cylinder holder assembly comprises: a plate-shaped body part which extends in an imaginary body part plane which extends perpendicular to the plate cylinder axis, wherein a side of the plate-shaped body part proximal to the plate cylinder axis forms a supporting ring support surface which extends substantially perpendicular to the body part plane and runs along a curve which extends in the body part plane, wherein the curve is mirror-symmetrical with respect to an imaginary curve symmetry plane which extends substantially perpendicular to the body part plane and with respect to which the anilox roller axis and impression roller axis are substantially symmetrically positioned and in which the plate cylinder axis extends, wherein the curve, viewed from the plate cylinder axis, comprises:
a central concave curve part which is symmetrical with respect to the central curve symmetry plane;a first convex curve part which adjoins a first end of the concave curve part and which extends to a first convex free end; anda second convex curve part which adjoins a second end of the concave curve part and which extends to a second convex free end, the two convex parts being symmetrical with respect to the curve symmetry plane; and a body part assist assembly via which the body part is connected with the associated frame part, wherein the body part assist assembly is configured for pivoting the body part about a first pivoting axis and for pivoting the body part about a second pivoting axis, wherein the first and second pivoting axes are symmetrically positioned on opposite sides of the curve symmetry plane, wherein the first pivoting axis substantially coincides with the impression roller axis, that is, coincides exactly with the impression roller axis or extends parallel to the impression roller axis with the distance between the first pivoting axis and impression roller axis being less than 50 mm, and wherein the second pivoting axis substantially coincides with the anilox roller axis, that is, coincides exactly with the anilox roller axis or extends parallel to the anilox roller axis with the distance between the second pivoting axis and anilox roller axis being less than 50 mm. |
