Definitions

  • the invention relates to a sheet transfer drum between Printing units in the side walls of a rotary printing press is stored.
  • DE-PS 36 02 084 shows a sheet transfer drum, which has three times the diameter of the plate cylinder.
  • This drum is designed so that from the full Cylinder required for rigid substrates Movement space was removed. That almost leaves one triangular contour. This contour shows that in the Advantages mentioned on patent.
  • the drum can be used to hold thin papers with sheet support elements full cylinder can be added.
  • the surface of this full Cylinder can in turn be provided with an anti-lubrication coating be.
  • DE-PS 35 36 536 and DE-PS 35 36 442 describe others Solutions with foldable slats, which can be adapted to should enable the substrate. However, it must Blown air protection against lubrication can be achieved. This Devices can only cover a smaller area Process substrates. For boxes must go through again strong use of blowing air combined with very high Operating and installation costs Lubrication-free be aimed for. For the particularly stiff materials such solutions, however, cannot be used.
  • the object of the invention is to provide a sheet transfer drum to create double large diameters without any elaborate Makeready times all substrates available on the market, i.e. Cardboard boxes, papers can be processed without smudging.
  • FIGS. 1 to 4 The invention is illustrated by FIGS. 1 to 4 described.
  • the blade effect of the drum contour is shown in FIG. 4 illustrated.
  • the design of the by guiding surfaces of the Drum core or the sheet guide plates, on the drum core generated contour geometry takes place in addition to the consideration of aforementioned trajectory also taking into account the Pressure conditions and air turbulence when rotating the drum.
  • the bow end 21 is in the confusing zone of the drum the pressure effect 17 pressed against the baffle 18.
  • the curvature of the baffle is only in contact with the Trailing edge where at the same time the separation by the arch between the overpressure and underpressure zone.
  • the cross section of the drum core 7 is whose side surfaces 2 are designed as guide surfaces can be thickest in the direction of the axis x, but in the The narrowest area of the grab bridges. Nevertheless, this one Drum core 7 in the area of the axis x of the cross section greatest distance from the theoretical drum circumference line 22.
