  • the sheetfed press does not need a cutting machine in the same way as a web-fed rotary printing press that requires cutting the web for processing, however, both types of press signatures as a stream of Transport printed products during press operation.
  • a stream of printed products can be gripped by a gripper conveyor, such as is generally known to the person skilled in the art. It is often desirable to include this product stream process, for example by dividing it into two or more separate streams or subjected to certain other processing such as conveying and stacking.
  • the conventional method of dividing a product stream, in particular Print products is to seal the original product stream over a vacuum belt pull, which runs slower than the conveyor system, and any other (i.e. second) signature release from a gripper conveyor as soon as the signature in question releases the vacuum belt contacted.
  • this often leads to a relative movement between the signatures, which are carried out on the vacuum belt and the signatures which are carried out by the Conveyor system remain in place. As a result, correct alignment and fixed Division (the distance between the same points of two consecutive signatures in a product stream) of the signatures supplied to the vacuum belt is not guaranteed become.

With a 45 degree turn one of the corners of the leading edge of the original product stream is the leading Corner. With a rotation of 135 degrees, however, one of the corners on the trailing can Edge of the original product stream will become the leading corner.
  • the individual grippers can be operated individually, so that a whole variety of Product sharing patterns can be achieved, such as sharing or pasting selected products whenever necessary. They are also alignment and division of the secondary product stream ensured because the products of the secondary Stroms do not have to be placed on a vacuum belt, which leads to changes in position the scale formation can lead.
