Web tension and wrinkles in the printing press
(Oklahoma State University, 1993-06)
In a modem paper mill the web handling in every process stage is optimized to fulfill productivity demands. The same kind of demands also exist in the printing plants. Smooth production without runnability disturbances is ...
On the web tension dynamics in an open draw
(Oklahoma State University, 1995-06)
Increasing productivity of paper machines, i.e. speeds, and requirements on decreasing basis weights of paper grades demand a deeper insight of the web tension behavior in the open draws. Runnability of a paper machine is ...
Effect of dual actuating strip guidance systems in a continuous steel annealing line
(Oklahoma State University, 1997-06)
In the past, Royal Hoogovens, a main primary steel and aluminum manufacturer in the Netherlands, used pre-shaped rolls and sophisticated tension tables to guarantee good strip tracking for all strip geometry's in both their ...
Comparison of center and surface winding using the wound-in-tension method
(Oklahoma State University, 1999-06)
Pfeiffer first defined the wound-in-tension measurement in 1968[1]. This technique requires the outer layer of web to be pulled away from a winding roll and a measure of the web tension is made prior to returning the web ...
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, ...
Web bagginess: Making, measurement and mitigation thereof
(Oklahoma State University, 2001-06)
Web bagginess is a defect so tenacious that few machines will totally escape its grip. It is so pervasive that it can be found on materials as diverse as tissue, writing paper, carpet, nonwovens, plastic film and steel. ...
Manufacturing and performance evaluation of carbon nanotube-parylene sandwich thin films
(Oklahoma State University, 2007-06)
Parylene-C, an inert and relatively mechanically strong polymer, which can be deposited in a conformal manner, is a promising substrate candidate for flexible electronics (Flextronics) devices. Parylene-CNT sandwich-films ...
Performance of paper tubes
(Oklahoma State University, 1999-06)
The tube performance requirements critical to a manufacturer's needs are dependent on such parameters as the manufacturer's processes, winding media, packaging, and equipment. Two important strength requirements for paper ...
Analysis of trough formation and lateral steering of a web due to a tapered downstream roller
(Oklahoma State University, 2005-06)
Cylindrical rollers are never perfectly cylindrical. A common defect of a cylindrical roller is radial taper. A roller with a radial taper will induce a lateral shear force into the web. This shear force will cause a ...
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 ...
