  • This stationary point of the printing table plate does not necessarily have to be rigid or even connected to the printing table base, but the connecting elements can be arranged so that a thermal expansion of the printing plate plate is possible only from the point-like or linear area.
  • the connecting elements for the application of holding forces in and against a holding direction are provided and mounted in relation to forces and displacements perpendicular to the holding direction substantially flexible or movably mounted.
  • the connecting elements are thus essentially designed as monovalent bearings.
  • univalent bearings are pendulum supports or roller bearings, in which forces can be transmitted in and against a holding direction, but perpendicular to the holding direction but shifts are possible.
  • fasteners By using such fasteners, the risk of tension is significantly reduced because holding forces are applied in different directions by different fasteners.
  • the connecting elements have first connecting elements whose holding direction runs perpendicular to the printing table surface, and second connecting elements, the holding direction of which runs parallel to the printing table surface.
  • the first connecting elements thus keep the printing table at a constant distance from the printing table base and are therefore primarily responsible for a table flatness with extremely small deviations.
  • the first connecting elements can be adjustable, for example, to be able to adjust a table flatness.
  • the first connecting elements can not hold the printing table plate against relative movements parallel to the printing table surface.
  • the second connecting elements are provided, the holding direction is parallel to the printing table surface.

  • the first connecting elements are designed as retaining bolts which are arranged perpendicular to the printing table surface are.
  • the retaining bolts have at least one circumferential groove and are bendable about the region of the circumferential groove perpendicular to its longitudinal extent.
  • retaining bolts allows the realization of a monovalent bearing in the manner of a pendulum support and at the same time opens up the possibility of adjusting the pressure plate plate with respect to their flatness over a length adjustment of the retaining bolt.
  • a plurality of adjustable retaining bolts are provided for this purpose distributed over the surface of the printing table plate.
  • a substantially flexible embodiment of the retaining bolts can be achieved by two spaced circumferential grooves on the retaining bolts, the depth of which is for example in the range of half the radius of the retaining bolt. In the area of the circumferential grooves, the retaining bolt can thereby be bent with comparatively little force, so that in the case of a thermal expansion of the pressure table plate, no significant tension and consequent distortions of the pressure table plate are to be feared.
  • the second connecting elements are formed as retaining tabs which are formed parallel to the printing table surface and parallel to its longitudinal extension for the application of holding forces and which are formed with respect to relative movements of the printing plate and printing table base perpendicular to its longitudinal extent substantially bendable.
  • the provision of retaining tabs allows very flat fasteners that can be easily arranged between printing table base and printing table top.
  • the retaining tabs may be formed, for example, as sheet metal parts, with retaining forces can be transmitted only in and against the longitudinal direction of the retaining tabs by appropriate design of the sheet metal blank. Perpendicular to the longitudinal direction, the retaining tabs can be deformed by very small forces are so low that no tension and consequent distortions of the printing table plate are to be feared in thermal expansion. This also applies to a deformation by rotation about the longitudinal direction, which also requires only small moments.
  • the retaining tabs are designed as sheet metal blank, for example, leaf spring-like.
  • the retaining tabs are formed by means of a free-cutting in a cover plate of the printing table base and / or a cover plate of the printing table plate.
  • the retaining tabs require no additional space between the printing table base and printing plate.
  • the retaining tabs can be cut out, for example, by means of a laser from the cover plate and are therefore easy and high precision to produce.
  • the retaining tabs are realized by means of a free-cutting in a cover plate, no separate components for the representation of the second connecting elements are required.
  • FIG. 1 a schematic side view of a printing table 10 is shown in the lower area, and a schematic plan view of the printing table 10 is shown in the upper area.
  • the printing table 10 has a printing table plate 12 and a printing table base 14, which are connected to each other by means of first connecting elements 16 and second connecting elements 18.
  • the first connecting elements 16 are shown only in the side view of FIG. 1 and shown in the left area of the side view as pendulum supports. In the right side of the side view of Fig. 1, the representation was selected by means of the symbol for a monovalent bearing. It is essential that the first connecting elements 16 can apply only holding forces perpendicular to the printing table plate 12 and thus keep the printing table plate 12 at a constant distance above the printing table base 14. Compared with displacements, for example caused by thermal expansion, parallel to the pressure table plate 12, the first connecting elements 16 are designed to be yielding. This applies to displacements or expansions of the printing table plate 12 in two mutually perpendicular directions X and Y, as indicated by the coordinate system indicated in the side view and the plan view. The connecting elements 16 can thus holding forces only in and opposite to their holding direction, namely perpendicular to the printing plate plate 12 and according to a Z direction, apply, displacements perpendicular thereto, however, are possible.

  • the connecting elements 18 were shown as pendulum supports, in the upper area symbols for univalent bearings were used.
  • the connecting elements 18 are designed and arranged so that they can apply only holding forces in and against a holding direction, wherein the holding direction of all second connecting elements 18 is parallel to the printing table plate 12.

  • the second connecting elements 18 are arranged so that they can apply holding forces only perpendicular to the imaginary lines 20, 22, 24, 26.
  • a thermal expansion of the pressure table plate 12 is thus possible starting only from the center 28, wherein the center 28 itself is always stationary relative to the printing table base 14.
  • the center 28 is not rigidly connected to the printing table base 14, since due to the special arrangement of the second connecting elements 18, a displacement of Center 28 relative to the printing table base 14 is not possible. This also applies to local heating and expansion of the printing plate 12. If the printing plate 12, for example, locally heated in a strip-like, indicated hatched area 30, a displacement of the center 28 is arranged opposite to the X direction by the perpendicular to the imaginary line 26 second connecting elements 18 prevented.
  • a displacement of the center point 28 in or against the Y direction is achieved by the second connecting elements 18, which are arranged perpendicular to the imaginary line 24, and by the connecting elements 18, whose holding direction is perpendicular to the imaginary line 20 and by the second connecting elements 18, which are arranged perpendicular to the imaginary line 22 prevents.
