Study of three-dimensional nonlinear nip mechanics
(Oklahoma State University, 1993-06)
An understanding of nip pressure and deformed nip geometry is of vital importance to the design of web handling equipment. Axial variations in nip pressure and deformed nip geometry can lead to poor product performance and ...
Theory and application of draw control for elastic webs with nipped pull rollers
(Oklahoma State University, 1993-06)
Draw control is defined as changing or maintaining web tension by controlling surface speeds of consecutive driven rollers. Even though draw control is commonly used in web handling applications, there remains some ...
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, ...
Simulation of wrinkling patterns in webs due to non-uniform transport conditions
(Oklahoma State University, 1993-06)
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 ...
