On-line control of tension in web winding systems based on wound roll internal stress computation
(Oklahoma State University, 2001-06)
One of the key challenges in the processing of flexible media such as plastic films is to obtain rolls without any aspect defect: if one considers that a "defect" (i.e. wrinkling or buckling) is due to the fact that the ...
Gauge optimization of the reference tension in winding systems using wound internal stresses calculation
(Oklahoma State University, 2007-06)
In winding process, the quality of the roll is directly connected to its stress state. The winding tension is the most significant parameter which plays an important role in the stresses generated within a roll, during ...
Control and online tension reference optimization in winding systems: Application to an identified three-motors simulator
(Oklahoma State University, 2005-06)
It is well known that the tension reference value, which a priori guarantees a good quality roll, is based on the stress generated within the roll. However, due to the imperfections of the winding systems and to the limited ...
