摘要： 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.

摘要： 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.
摘要翻译：提供了一种系统和方法，用于确定在张力下通过印刷机移动的幅材的未张紧产品长度。控制器在幅材在张力下移动通过印刷机时确定幅材在印刷机的跨度中的张紧重复长度; 当幅材在张力下移动通过印刷机时，确定幅材在印刷机跨度中的弹性应变; 并且当幅材作为张力重复长度和弹性应变的函数在张力下移动通过印刷机时，计算出印刷机跨度中幅材的未张紧产品长度。
