ABSTRACT:
The invention provides an aid for threading a printing-material web or part printing-material webs which are produced from the printing-material web by a longitudinal cutting device. The aid enables threading by a threading apparatus even in the region of offset bars. For this purpose, guide bars are introduced into the web course during the threading operation. The printing-material web is threaded through the offset bars but wraps around these guide bars instead of the offset bars. The guide bars are then either withdrawn from or pivoted out of the web course so that the printing-material web can be pulled taut on the guide bars. Likewise, it is also possible for offset bars mounted on one side to undertake the function of the guide bars during the insertion operation.
