Prevention of web floating at wrapped transport and guide rollers
(Oklahoma State University, 2003-06)
Increasing productivity of web converting machines requires constructive improvements for the prevention of web floating at transport and guide rollers. Existing solutions which carry off the air like vacuum or grooved ...
Complete material law of paper for modelling and simulation of finishing processes
(Oklahoma State University, 2005-06)
A complete three-dimensional material law is necessary for the mathematical description of the material behaviour and for the simulation and calculation of finishing or converting processes. In order to achieve this goal, ...
Interactions of time dependent, thermal and hygroscopic characteristics and runnability properties of paper
(Oklahoma State University, 2007-06)
For purposes of design and optimization of industrial processing, many of the physical properties of paper have to be taken into account. The knowledge of the mechanical properties as part of the physical ones must be ...
Phenomens of rolling contact in paper calendering
(Oklahoma State University, 2009-06)
In soft calenders synthetic roll covers are "state of the art", without knowing their detailed rolling contact behavior and their phenomenological effects to gloss and smoothness of paper. Complex interactions of process ...
Influence of the gap throttle effect on the winding process and roll quality
(Oklahoma State University, 2005-06)
In the paper industry the winding technology has a significant influence on the quality of finished rolls. The rising productivity and quality efforts require a constant optimization of the winding process concerning the ...
Regulation concept for web spreading equipment in web processing machines on the basis of neural networks
(Oklahoma State University, 2001-06)
Web spreading systems are used in converting machines in order to guarantee a folding free web transport and a sufficient slit gap or slit separation. The adjustments, dependent on the respective application, are carried ...
Future online concept for roll and sheet production in papermaking technology and process requirements for web handling
(Oklahoma State University, 2003-06)
The process of on-line converting is discussed as a chance to increase the productivity and quality in roll and sheet converting in paper mills. In this article the technical and process related prospects will be presented ...
New objective method for quantitative assessment of cut edge quality for paper and board
(Oklahoma State University, 2001-06)
In the paper converting and finishing industry the cut edge quality is of particular importance to the manufacturing processes, e.g. the printing process. In this paper an objective method for the quantitative evaluation ...
Optimized slitting parameters for the shear slitting of paper
(Oklahoma State University, 2003-06)
Due to the demand for an increasing quality of cutted or slitted products and the requirement of rising productivity in the slitting process, the optimization of mechanical slitting is gaining in importance for the converting ...
