Mechanics of cambered web belts on aligned rollers
(Oklahoma State University, 2019-06)
The lateral deformations of webs in roll-to-roll (R2R) process machines can affect the quality of the manufacturing process. Webs can enter a cylindrical roller normally if the forces required to sustain normal entry and ...
Web length creep in wound rolls
(Oklahoma State University, 2019-06)
For convenience, webs are stored in wound rolls. The available web length in a wound roll is one mark of roll quality and a concern for many who process and convert webs. Elastic winding models have proven very precise at ...
Predicting the web length and layers in a wound roll
(Oklahoma State University, 2019-06)
The length of web in a wound roll is one mark of roll quality. The available web length in a roll is a concern for many who process webs and those who convert webs. There are algorithms that estimate the length of web and ...
Assessing wound roll quality using a measured stiffness/model method
(Oklahoma State University, 2019-06)
For those concerned with roll quality it is difficult to suppress the urge to compress the outer surface of a wound roll with your thumb to sense how tightly the roll was wound and how large the internal pressures might ...
