Abstract: 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.

Abstract: A system and method is provided for closed loop control of an untensioned product length of a web moving through a printing press under tension during production. While a printing press is printing on the web, a controller receives a calculated untensioned product length Lo(t) of the web in the span of the printing press while the web is moving through the printing press under tension, compares L0(t) to a previously stored untensioned product length setpoint Lsetpoint, maintains closed loop control of the untensioned product length by controlling one or more components on the printing press as a function of said comparing step, and repeats the steps receiving, comparing, maintaining and controlling over time while the printing press is printing on the web.

Abstract: Method and apparatuses for measuring and regulating the strain of a material web is disclosed. A material web is passed through a first and second non-slip roller pair. The first and second roller pair form a predefined span. In some embodiments, the angular positions of the first and second roller pair are monitored, and the phase angle between the roller pairs is calculated. The phase angle is directly related to the level of strain in the web, and the velocity of the web is controlled to maintain a phase angle which corresponds with the desired strain level. This maintains a constant strain level in the predefined span. In one embodiment, the strain entering a non-slip roll pair is controlled to be zero. The roll pair then introduces a predefined strain to the span entering subsequent processes.

Abstract: A web offset print unit includes a first plate cylinder, a first blanket cylinder selectively in contact with the first plate cylinder, a second blanket cylinder, the web passing between the first and second blanket cylinders, the second blanket cylinder and first blanket cylinder being selectively disengageable from the web in a throw-off position to permit the web to pass between the first and second blanket cylinders, and a second plate cylinder selectively engageable with the second blanket cylinder. A single drive motor drives the first plate cylinder, first blanket cylinder, second blanket cylinder and second plate cylinder when the first and second blanket cylinders engage the web and the single drive motor rotates the first and second plate cylinders when the first and second blanket cylinders are in the throw-off position. Autoplating during the throw-off position thus is possible.
