Tension control of webs - A review of the problems and solutions in the present and future
(Oklahoma State University, 1995-06)
Production plants with continuous moving webs have a complex structure where mechanical and electrical problems are involved. To solve the problems of this systems, it is necessary to take into account the total system to ...
Web tension in a flotation dryer
(Oklahoma State University, 1997-06)
In a flotation dryer, the web rides on a cushion of air and typically takes a "sine wave" path over the air bars. The non-straight path and the elastic effect of the air cushion interact with the normal tensioning of the ...
Coupling between out-of-plane displacement and lateral stability of webs in air-support ovens
(Oklahoma State University, 1995-06)
In drying ovens where the web zig-zags over and under air-support bars, the web sometimes drifts to one side or the other until it runs into the oven wall. This divergence is shown to be coupled to out-of-plane displacements ...
Revised Sievers lateral dynamics model
(Oklahoma State University, 1999-06)
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 ...
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 ...
Wound roll stress analysis including air entrainment and the formation of roll defects
(Oklahoma State University, 1995-06)
Numerous procedures have been developed to determine the stresses inside wound rolls of film. These typically use factors such as winding tension, film thickness and film properties to calculate the stresses. The calculation ...
