A system and method is provided for determining an untensioned product length of a web moving through a printing press under tension. A controller determines a tensioned repeat length of the web in a span of the printing press while the web is moving through the printing press under tension; determines an elastic strain of the web in the span of the printing press while the web is moving through the printing press under tension; and calculates an untensioned product length of the web in the span of the printing press while the web is moving through the printing press under tension as a function of the tensioned repeat length and the elastic strain.

System and method for measuring untensioned product length of a web during production

A noncontact web stabilizer is provided in which members located on opposite sides of a web reduce out-of-plane web vibrations. Specifically, a first member is located on one side of a web and a second member is located on the opposite side of the web. Both members are positioned so that the distance between the web and the members decrease in the direction that the web is moving, creating opposing regions of high pressure that force the web toward its nominal running position, thereby reducing out-of-plane web instability.

Noncontact web stabilizer

The present invention concerns an apparatus for preventing condensation in machines for processing web-like material, and in particular an apparatus for preventing condensation on the safety guard of a printing press. The apparatus includes components of a processing unit, and elements assigned to the components to maintain the surface temperature of the components above the dew point of the surrounding air.
