Definitions

  • sheets are started depending on their type - specifically their length and/or weight - at different times, i.e., fed by the respective feeding unit to the transport path, in order to apply a counter-error to potentially (even with respect to each other) wrong positioned sheets as expected during transport for correction at the onset, so that the desired position will be taken during transport.
  • a modification in this case provides that information for the selection of the starting time is yielded beforehand by at least one trial run with at least one type of printing material, preferably by trial runs with different types of material, while a corresponding empirical table is created, for example, configured as a look-up table, i.e., a specified table.
  • a feeder 1 for sheets of printing material a feeding segment 2 for sheets of printing material from said feeder 1, in which case also more than one feeder may be provided, and a pocket 3 for sheets of printing material, in which case an output segment 14 leads to said pocket.
  • the main part of a transport path for sheets of printing material consists of a duplex turning loop 5, which represents a segment of the transport path, the turning operation being symbolically indicated by bent arrows 16.
  • An integral part of this duplex turning loop 5 is a closed rotating transport belt 4, which, in particular, moves the sheets of printing material past printing units 15 in order for said sheets to be printed.
  • sheets having different weights exhibit different running time behavior in turning loop 5 and that sheets 6, 9, respectively, are to be batch-processed, in which case the number of sheets 6, 9, indicated here only as an example and sporadically for the sake of clarity, in a batch is such that the sheets of the batch just fill the turning loop 5, and that successive batches are to follow in registered position. Therefore, for potential skew correction in accordance with the invention, sheets 6, 7, 8, 9 experience two velocity changes in the duplex turning loop, i.e., at the sites indicated by dashed arrows 19 and 20, which is respectively downstream of turn 16 and upstream of lead edge sensor 13. Transport path segments exhibiting different speeds, for example, make sense even without skew correction in order to be able to feed sheets from feeder 1 at high speed into turning loop 5, for example, and be able to print, with printing units 15, at a relatively low process speed.
  • the pair of transport rollers 29 is followed by another pair of transport rollers 31, to which the sheet can be transferred. Apart from that, the further progress of the transport path is not illustrated in detail.
  • a sensor - in viewing direction of an arrow 32 - is provided for sheet detection, whereby said sensor may also be connected with electronic control means 30 in order to detect the time of arrival of the trailing edge of said sheet.
