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 ...
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 ...
Industrial use for the "nip-inducted effect" to separate sheets
(Oklahoma State University, 2009-06)
This paper introduces an analytical method for the explanation of the nip inducted effect. This effect is known for a long term as a disturbance effect in the web handling industry. Here it is used for breaking bindings ...
Lateral mechanics of an imperfect web
(Oklahoma State University, 2001-06)
A model describing the lateral mechanics of an imperfect web has been derived which brings forward information on the much debated fourth boundary condition. The model is based upon a generalized beam theory. Calculations ...
Air entrainment on two sides of a web passing through the nip of two rigid rolls
(Oklahoma State University, 2001-06)
When web materials (paper, plastic films, or metal foils) are wound into rolls, excessive amounts of air can be entrapped between layers of the web, resulting in defective rolls. Entrapped air layer between a coated film ...
What we know that just isn't so
(Oklahoma State University, 2007-06)
This paper proposes a metric for the permeation of the science of web handling into industry. The variable of interest is misunderstandings, myths if you will, that are common in plants. The origin of the myths is unimportant ...
Gauge optimization of the reference tension in winding systems using wound internal stresses calculation
(Oklahoma State University, 2007-06)
In winding process, the quality of the roll is directly connected to its stress state. The winding tension is the most significant parameter which plays an important role in the stresses generated within a roll, during ...
Recent advances in web longitudinal control
(Oklahoma State University, 2005-06)
Stable web transport through processing machinery is critical in the web processing industry. Demands for improved performance under a wide variety of dynamic conditions and web materials are placing additional emphasis ...
Calculating coilset based on curvature of a web
(Oklahoma State University, 2003-06)
A web which has passed over a roll can exhibit coilset due to differential yielding of fibers through its thickness. Modeling can provide a radius of curvature, R, the web would achieve if no external forces were applied. ...
