Mechanics of grooved flexible spreader rolls
(Oklahoma State University, 2007-06)
All known web spreading hardware work based upon one of three principles. Sometimes it is unclear which principle(s) apply to a given spreading device. The flexible spreader roller is such a device. In this paper we will ...
Analysis of web spreading induced by the curved axis roller
(Oklahoma State University, 1993-06)
This paper describes the development of a model for predicting the elastic deformations and stresses in a web crossing a curved-axis roller. The Finite Element Method was used to compute web displacements, forces and ...
Air entrapment and residual stresses in rolls wound with a rider roll
(Oklahoma State University, 1995-06)
Air is entrained during the process of winding webs. Rider rolls are often employed in an effort to reduce the amount of air which enters the wound roll. This paper presents the results of an experiment which allows the ...
Surface compression of wound rolls
(Oklahoma State University, 2013-06)
Stress levels and profiles in the vicinity of contact between a wound roll and a nip or a rigid surface are important for the quality of the product during manufacturing or storage stages. Excessive or insufficient pressure ...
Nip impinged center-winding including a nonlinear beam model
(Oklahoma State University, 2017-06)
Nip pressure is commonly applied in winding processes in order to maintain structural stability and prevent air entrainment at high speeds. In nip induced winding modeling nip and roll are assumed to be beams with ...
Coupling of winding models and roll quality instruments
(Oklahoma State University, 2015-06)
Winding models have been under development for roughly 50 years. These models have become mature in their ability to predict the internal residual stresses within a wound roll as a function of winder type, winder operating ...
