ABSTRACT:
A web printing apparatus includes a positively driven printing base, a drive for driving a web to be printed over the printing base, and rollers positioned to contact and print a first portion of the web opposite the printing base. The drive moves the web at a higher speed than the base. The rollers press down on the web with sufficient force to create a friction connection between the web and the base, thus retarding and reducing the speed of the first portion of the web and tensioning a second portion of the web downstream of the rollers. The tension thus created in the second portion of the web is used to reduce the speed thereof.
