Computing wound roll stresses based upon web surface characteristics
(Oklahoma State University, 1993-06)
Historically wound roll models have required the input of a radial modulus of elasticity. Heretofore this modulus has been measured using material testing systems which have shown the radial modulus to be dependent upon ...
Analysis of web spreading induced by the concave 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 concave (or negative crown) roller. The Finite Element Method was used to compute web displacements, ...
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 ...
