Issues in modeling slitting of magnetic tapes
(Oklahoma State University, 2003-06)
In order to quantify and understand the driving force for film layer fracture, delamination, and the cutting phenomena in general, an idealized two-dimensional "slitting" model was developed. The model includes two lower ...
On-line control of tension in web winding systems based on wound roll internal stress computation
(Oklahoma State University, 2001-06)
One of the key challenges in the processing of flexible media such as plastic films is to obtain rolls without any aspect defect: if one considers that a "defect" (i.e. wrinkling or buckling) is due to the fact that the ...
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 ...
Measurement of web surface profiles using fringe projection
(Oklahoma State University, 2009-06)
In this paper a full-field measurement technique, namely fringe projection technique was implemented to determine the three-dimensional surface profile for situations where webs are opaque or translucent. In this method, ...
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)
Prediction model of paper-web wrinkling and some numerical calculation examples with experimental verifications
(Oklahoma State University, 2005-06)
In the web handling technology, it is very important engineering problems to predict and protect web wrinkling from several view points of product quality, manufacturing cost and so on. In this paper, the prediction model ...
Roll-to-roll gravure printed smart food package to replace the "use-by" date system of foods
(Oklahoma State University, 2019-06)
The implementation of internet of things (IoT) to the food industry offers a great deal, accompanying each functional unit from production to the consumption to ensure the quality of a particular food item. Among several ...
Experimental and numerical studies of the reelspool and the parent roll interaction under gravity forces
(Oklahoma State University, 2001-06)
In wide paper machines, gravity forces may cause excessive stresses to the paperlayers of the parent roll due to bending of the reel spool. Experimental and numerical studies of these effects will be described in this ...
