Abstract
The action pattern of the amount of web feeding by the lug folding flaps is made optimal in accordance with deviations of detection marks, such as specified printing patterns on the printing surface on web W, from the reference values when they are detected, and the pressing force applied onto web W by dancer roller 9 is stepwise or continuously adjusted according to the detection of the patterns. Therefore, in comparison with the conventional examples, it is possible to widen the corrective range for the amount of web feeding. Thus, the tolerance for printing errors on web W can be increased, and it is possible to operate the equipment without stopping. Furthermore, it is possible to produce packaging containers with printing patterns applied at appointed positions, and faulty products are eliminated.
