Abstract
Bag sections that pass through a machine are scanned as to their spatial positions within the machine. The measuring points have been arranged at distances corresponding to the stroke of the machine, so that it is possible to intervene in the operation of the machine when a deviation from a given nominal position occurs, before a stopper formation occurs. Each bag section that comes into the machine triggers a subsequent comparison of nominal and actual values in a manner such that the signals of defects that are generated by the lack of work pieces, are neutralized.
