ABSTRACT:
A web and an associated web feeding and handling apparatus for performing a work operation on the web is disclosed. The apparatus feeds the web in a feed direction longitudinally of itself by means of a friction drive. The operation of the drive is controlled by lateral and longitudinal alignment indicia located on the web which insure that the web is properly aligned with the feed direction as the web is initially fed into and then through the apparatus, and to insure that any bowing of the web during the work operation is corrected or compensated for.
