Definitions

  • the invention relates to a blanket cylinder for sheet-fed offset printing machines, which is provided with a device for covering the cylinder channel, according to the preamble of claim 1.
  • the disadvantage here is that the channel cover does not offer optimal protection against the penetration of liquid detergents used in cleaning the cylinders or does not offer optimal protection against the penetration of water or color-water emulsions.
  • a further disadvantage is that the device for channel cover arranged in the cylinder channel can only compensate for insufficiently existing unbalances of the rotating blanket cylinder, because the masses and the masses formed by the components of the channel cover cannot form sufficient counterweights for dynamic balancing.
  • the object of the invention is to provide a cover rail for the wide cylinder channel of a sheet-fed rotary offset printing press, which makes it possible, in conjunction with the clamped rubber blanket, to shield the entire area of the cylinder channel tightly against the ingress of liquids, thereby preventing the rubber blanket from loosening and at the same time to better compensate for imbalances of the rotating blanket cylinder.
  • the main advantage of the cover rail according to the invention is that liquid detergent, water or the like can no longer penetrate into the cylinder channel of the blanket cylinder, so that disruptions in the printing process due to such liquid accumulations in the cylinder channel are excluded from the outset.
  • the parts of the blanket cylinder located under the cover rail e.g. the tensioning devices for the rubber blanket, for elevators and the like are better protected against corrosion.
  • the cover rail according to the invention also forms a suitable counterweight in order to better compensate for imbalances occurring in sheet-fed rotary offset printing machines.
  • the wide rail head of the cover rail also secures the position of the rubber blanket so that it cannot loosen easily. Last but not least, the cover rail serves to avoid injury to operating personnel in the wide cylinder channel.
  • the blanket cylinder 1 has an axially parallel cylinder channel 2.
  • a rubber blanket 5 is stretched on its cylinder jacket.
  • the ends 6, 7 of the rubber blanket 5 are inserted by means of tensioning spindles 3, 4 in the cylinder channel 2, and by turning the tensioning spindles 3, 4, the rubber blanket 5 is stretched on the outer surface of the blanket cylinder 1.
  • the rubber blanket 5 is pulled over the channel edges.
  • the cover rail 8 extends over the entire length of the cylinder channel 2 to close to the side walls 13, 14 of the blanket cylinder 1 and has an approximately mushroom-shaped rail profile shape in cross section.
  • the rail head 9 is dimensioned so that its width is approximately equal to the distance between the central axes of the clamping spindles 3, 4. This round-edged rail head 9 is supported over the stretched blanket 5 on the clamping spindles 3, 4 along the cylinder channel 2. Between pages walls 13, 14 and the lateral surfaces of the rail head 9, a sealing compound 16, 17 is provided.
  • the cover rail 8 also represents a counterweight to the dynamic balancing of the rubber blanket cylinder 1. At the same time, a loosening of the rubber blanket 5 on the channel edges is prevented, since the rail head is in contact with the rubber blanket 5, with a slight clamping effect of the screwed-in cover rail 8.
  • the cover rail 8 is provided with a radius of curvature in the region of the transition from the rail web 10 to the rail head 9 and adapted in size so that a gap corresponding to the thickness of the rubber blanket 5 to the clamping spindles 3, 4 remains.
