ABSTRACT:
Packaging material, particularly for forming blanks for hinged lid packets, is delivered to a packaging machine in web form and at least one creasing or shaping operation is performed (44; 112) on the web (2) prior to severing individual blanks (50) from the web. Folding or wrapping of a blank around an article to be packed in the machine is monitored and the creasing or shaping operation varied to optimise machine performance: for example, an adjustable creasing tool can be adjusted to compensate for tool wear. Individual blanks are inspected for longitudinal curl, usually caused by the web having been wound on a reel, and where necessary a correction is applied during feeding of the web, e.g. by adjusting the angle of wrap of the web around a decurling roller (38; 108).
