The changeover takes place here to different cutting lengths of signatures in that an inner and an outer part of the Cylinders are rotated against each other. This is through allows an additional, second gear train.
  • the disadvantage here is an increased volume of the Cutting cylinder and the need for a second Gear train.
  • DE-C-671 790 describes a cutting device for Cross cutting of running webs, being in one first operating mode two cutting blades diametrically opposite and in a second operating mode Cutting knife offset to the second cutting knife is arranged.

  • the advantages which can be achieved with the invention consist in particular in that a simple changeover of the cutting device from "non-collecting operation” to “collecting operation” is possible.
  • the cutting cylinder can be rotated with respect to the collecting cylinder by a simple phase adjustment, which saves time and thus reduces the set-up costs.
  • the size and structure of the cutting cylinder are not changed, which is why previous cutting cylinders can be used.
  • Existing cutting cylinders with helical toothed drive wheels can also be retrofitted, since only one axial displacement device has to be provided for the drive wheel.
  • a correction of the cutting register is also possible due to the phase-changeable cutting cylinder. So-called snipping can also be avoided.

To adjust the cutting cylinder 3 to its collecting position, a first cutting knife 23 is displaced, for example by changing the spacer 24, by an amount l parallel to the plane of symmetry 16, so that the cutting knives 23, 25 are no longer opposite one another, but are offset by this length l.
