  • the disadvantage is that tolerances in the distances between the individual sheets within the group can not be compensated and so a jam during threading can occur.
  • the single sheet B1 to be led from the printing unit D2 to the printing unit D1 is to be threaded between the individual sheets B6 and B7 on the switch W2.

Consequently, the single sheet B1 is reduced in its speed to the speed of the single sheet B7.
  • the cut sheet B7 leaves the printing area, preferably the area of the decurler, in the printing unit D1, it can be transported at increased speed again. Also, the single sheet B1 is then transported forward at an increased speed and reaches the transport path 50. The single sheet B1 is transported at a consistently increased speed to the area at the switch W6 and then controlled down to transfer printing speed. The time to reduce the transport speed of the single sheet B1 can be matched to the leading single sheet B11. Then, the gap between the end of the cut sheet B11 and the beginning of the cut sheet B1 can be set at the nominal pitch or slightly larger.
  • the other single sheets B2, B3 etc. within the group of individual sheets are transported in a similar manner as has been described for the single sheet B1.
  • controlled threading takes place at the shunt W2. This reduces the risk of congestion during threading and the distance between the individual sheets can be minimized.
  • the disadvantage is the increased control and control effort when threading.
  • the leaves can be threaded controlled on the switch W2, a second transport control path in the region of the switch W1 is required in addition to a transport control path in the region of the switch W2.
  • the operations and transport speeds of the single sheets from the input 16 to the switch W4 are consistent with those described in ungetriggered operation.
