Definitions

  • the invention relates to a sheet support device for bridging a page mark recess, which extends transversely to the sheet conveying direction over the width of the feed table, depending on the format in a maximum and a minimum position, of a rotary printing press. It can be used when processing paper, cardboard or sheet metal.
  • Such a bow support device is known from DE-AS 1 611 362 as a "scissor lattice table".
  • corrugated, vertically high ridges and supporting the supplied sheet of spring strips are arranged as length-adjustable table surfaces within the side mark recess.
  • a plurality of displaceable receiving elements are arranged in the gap area transversely to the sheet conveying direction.
  • the receiving elements which act as leaf springs and are guided on rods, have leg regions and V-shaped or U-shaped connecting regions which are arranged in an upright position in the plane of the table surface. They are pre-tensioned and can be compressed when the side mark recess is reduced and they adjust themselves when the recess is enlarged.
  • cover device In the recess of the feed table, spring-supported cover webs are arranged so that they can move vertically to the table surface. A sliding block acts on the cover webs from above and presses them into the recess against the spring force.
  • the object of the invention is to eliminate the disadvantages known from the abovementioned prior art. This is solved by the features of the characterizing part of the main claim. Further training results from the subclaims.
  • the solution according to the invention ensures reliable guidance of the printing material by the guide bridges lying parallel to the conveying direction, since no spring elements come into contact with the printing material. Dust and dirt can be removed and additional means for guiding the bend can be introduced into the recess, since the guide bridges can be quickly replaced with and without a spring element. Changes in size in the conveying direction are excluded, so that malfunctions when dirty cut or damaged edges of the substrate can be avoided.
  • the spiral springs are pre-tensioned so that they can be compressed for setting to small substrate sizes (minimum distance) and automatically adjust themselves to the maximum distance for setting to larger formats.
  • the guide bridges always remain parallel to the conveying direction and are always in the plane of the feed table.
  • the sheet support device is formed in a recess 10, which is delimited by a feed table 6, a feed plate 5 and a side mark 1.
  • a feed table 6 and feed plate 5 Parallel to the feed table 6 and feed plate 5, two spaced cross members 2 are arranged in a stationary manner below the cutout 10.
  • a large number of guide bridges 4, spanning the distance between the contact plate 5 and the contact table 6, are arranged on the cross members 2, parallel to the sheet conveying direction 7 (at right angles to the cross members 2).
  • Each guide bridge 4 is positively supported on the crossbeams 2 and forms a thrust joint 9 in this area.
  • the surfaces of the guide bridges 4 lie at the same level with the surfaces of the feed table 6 and contact plate 5.
  • an elastic spiral spring 3 for example a leaf spring, is arranged in an upright position, which is centered on the Side surface of the guide bridge 4 is fixed in position by connecting elements 8.
  • the torsion spring 3 is supported with its legs on the side surface of the adjacent guide bridge 4.
  • the length of the legs of the spiral spring 3 is shorter than the length of the guide bridge 4 in the compressed state (extended length) Printing material does not come into contact and the sheet is only supported by the guide bridges 4.
  • the side mark 1 is adjustable transversely to the conveying direction 7 depending on the format on the feed table 6.
  • the format is reduced, it is moved in the direction of the center of the feed table within the cutout 10, which reduces the distance between the guide bridges 4 and the bending springs 3 are compressed (minimum distance position).
  • the side mark 1 is moved in the direction of the outside of the feed table 6.
  • the elastic spiral springs 3 relax and the guide bridges 4 align themselves automatically within the recess 10. They are guided exactly over the thrust joints 9 formed with traverses 2 up to the maximum distance position.
  • the exemplary embodiment described can be further developed by arranging elastic spiral springs 3 on both side surfaces of the guide bridge 4.
  • Guide bridges 4 with spiral springs 3 and guide bridges 4 without spiral springs 3 alternate within the recess 10.
  • a further embodiment is achieved in that spiral springs 3 are arranged on each guide bridge 4 on both sides.
  • the adjacent spiral springs 3 are arranged at different levels or penetrate each other. The prerequisite is that the upper edges 11 of all spiral springs 3 remain below the level of the guide bridges 4.
