Prediction model of paper-web wrinkling and some numerical calculation examples with experimental verifications
(Oklahoma State University, 2005-06)
In the web handling technology, it is very important engineering problems to predict and protect web wrinkling from several view points of product quality, manufacturing cost and so on. In this paper, the prediction model ...
Improvement of web spacing characteristics by two types of guide rollers
(Oklahoma State University, 1999-06)
In the manufacturing fields of plastic sheet, paper, magnetic tape, thin metal plate, photographic film etc., the web transporting systems supported by guide rollers are often used. In such systems, it is of cardinal ...
In-roll stress analysis considering air-entertainment at the roll-inlet with the effect of grooves on nip roll surface
(Oklahoma State University, 2005-06)
High-speed winding of paper web sometimes leads the winding system into unstable states, interlayer slippage of wound roll, paper breakage and so on, due to the excessive air-entrainment at the roll-inlet of nip contact ...
Prevention of wound roll defect of coated web
(Oklahoma State University, 2009-06)
The web which is coated with a coating agent on the surface to add a function is called coated web. This coated web is often made into wound roll to ease handling and storage after coating, and then it is passed to next ...
Theoretical modeling of traction characteristics between paper-web and steel-roller based on the contact mechanics
(Oklahoma State University, 2005-06)
This report describes the theoretical modeling of friction coefficient between uncoated paper web (newsprint; for example) and steel roller. In the modeling, the paper base is approximated by the linear spring and surface ...
