This is the case. if e.g. B. the printing of a material web with a printing cylinder with signatures with two different printed images in each revolution Printed circumferential direction. Then when the signatures cut off the web become. the signatures alternately contain one of two different ones Print images. It is often desired.

  • friction forces an instantaneous transition of the signature from the original Speed vector to a new speed vector making conventional Shock curves have considerable disadvantages.
  • One of the disadvantages is the unreliability of the Shock curves when initiating a new speed vector.
  • Another disadvantage is that there is a risk of damage to the signatures and / or a jam in the press exists.
  • conventional shock curves cannot be separated the "A" signatures are used by the "B" signatures. Rather, one must separate downstream separating device can be used to the To split the signature stream into several sub-streams.

It is therefore necessary to have the bow already to be offset laterally before entering the device, so that there is a free side section on each individual sheet.
  • the Splitting the sheet by such a device can therefore only with the help of a upstream device for lateral pre-separation or relocation of the sheets happen.

A However, these incoming product flows are not divided. The merged product flows are in turn deflected at one point which is also possible to split the current. However, the Product streams have twisted signatures for distribution in the transport direction, so that there are free side areas to grab the signatures. Consequently also teaches DE 196 43 395 A1, the pre-separation of the transported products before the actual separation.
