A closed-loop system can maintain a pre-set cut length of a material as the material
is cut and placed on a web. The system has the ability to measure the actual cut
length, compare the average actual cut length to a target cut length, and to adjust
web tension or feed roll speed to achieve the target cut length. Actual cut length
variation is thereby reduced. Furthermore, short term cut length variation is further
reduced by minimizing the tension of the web just prior to the material being cut.
