    • Reading a roll 

      Roisum, D. R. (Oklahoma State University, 1997-06)
      Web or winder defects often leave a visible record of themselves in the wound roll that can be read much like the rings of a tree. Varying strains in each layer as it is wound will cause changes in geometry that can be ...

    • Real time data analytics as applied to web-to-roller traction in manufacturing 

      Cole, Kevin A.; Hopkins, R. W.; Hotto, N. A.; Scheible, J. J.; Schneider, Brooks J.; White, Thomas J. (Oklahoma State University, 2019-06)
      Avoidance of web handling-related imperfections is often a challenge. As an example, the limit of web-to-roller traction is typically not detected until it is exceeded, resulting in product damage. Detection is often made ...

    • Real time dynamic simulation for control system software verification 

      Bettendorf, R. (Oklahoma State University, 2001-06)
      It is a common practice in the paper industry to verify large portions of the control system software during machine commissioning. This is inefficient since the verification is done under production conditions when time ...

    • Real time dynamic simulation of a paper winder 

      Bettendorf, R. (Oklahoma State University, 2003-06)
      Typically, large portions of the winder control system software are tested during the commissioning process. This is inefficient since production is shut down and financial pressures limit the time available for testing. ...

    • Real-time tension control in a multi-stand rolling system 

      Shin, K. H.; Hong, W.K. (Oklahoma State University, 1995-06)
      The problem of real-time tension control in a metal-strip processing line is addressed. The tension in a metal strip changes due to not only the speed difference but also thickness changes at the ends of a span. The ...

    • Recent advances in web longitudinal control 

      Pagilla, P. R.; Knittel, D. (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 ...

    • Refining our rules of thumb 

      Lynch, Ronald (Oklahoma State University, 2015-06)
      Rules of thumb are common in web handling for good reasons. Many of the theories of web behavior are still under investigation and often are complex and a function of properties that are difficult to measure. Because of ...

    • Regulation concept for web spreading equipment in web processing machines on the basis of neural networks 

      Welp, E. G.; Wang, D.; Kleinert, A. (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 ...

    • Resiliency of an air-floated web 

      Chang, Y. B.; Swanson, R. P.; Moretti, P. M. (Oklahoma State University, 1999-06)
      Air-flotation ovens are used for non-contact drying of coated web materials such as photographic film, magnetic media, and paper. In a typical air-flotation oven, the air bars are arranged in such a way that the path of ...

    • Revised Sievers lateral dynamics model 

      Walton, R. L. (Oklahoma State University, 1999-06)

    • Robust control design using H-infinity methods in large scale web handling systems 

      Knittel, D. (Oklahoma State University, 2003-06)
      This paper presents H-infinity control strategies for elastic web transport systems. The aim is to reduce the coupling between web tension and web transport velocity. First of all, a multivariable H., centralized controller ...

    • Role of active dancers in tension control of webs 

      Pagilla, P. R.; Perera, L. P.; Dwivedula, R. V. (Oklahoma State University, 2001-06)
      This paper investigates the role of active dancers in attenuation of web tension disturbances in a web process line. A general structure of the active dancer is considered; an input/output model is developed for analysis ...

    • Roll design effect on nip pressure 

      Simbierowicz, G.; Vanninen, R. (Oklahoma State University, 2005-06)
      The quality of reeling process is a key factor in achieving production efficiency, especially when machine speed and paper width continue to increase. For calendered and coated grades of paper the main problems are the ...

    • Roll speed and web tension regulation using two degree of freedom control systems 

      Raul, Pramod R.; Pagilla, Prabhakar R. (Oklahoma State University, 2015-06)
      In this paper, we first consider the problem of load speed regulation in a two inertia system consisting of a motor shaft connected to the load shaft via a mechanical transmission. The problem is reminiscent of a material ...

    • Roll variability analysis for non-statisticians 

      Thuer, Amy; Dennison, Avery (Oklahoma State University, 2019-06)
      Roll variability can be characterized by several different methods. Off line cross-direction (CD) scans of thickness or coat weight give a snapshot of CD variation over a small machine-direction (MD) range. Roll hardness ...

    • Roll-to-roll gravure printed smart food package to replace the "use-by" date system of foods 

      Maskey, Bijendra Bishow; Koirala, Gyan Raj; Kim, Seongryeong; Sun, Junfeng; Shrestha, Kiran; Kim, Yushin; Park, Hyejin; Cho, Gyoujin (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 ...

    • Roller nip deflections 

      Cole, Kevin; Schneider, Brooks (Oklahoma State University, 2017-06)
      Rubber covered nip rollers are used in many web handling and processing applications. Successful use of these systems requires an accurate knowledge of the impact of various design and process parameters on key response ...

    • Sensorless tension control of webs 

      Wolfermann, W. (Oklahoma State University, 1997-06)
      Production plants with continuous moving webs have a complex structure where mechanical, electrical and control problems are involved. To solve the problems of these systems, it is necessary to take the entire system into account.

    • Sensors and signal processing: An optical edge sensor for transparent film applications 

      Gronquist, D. (Oklahoma State University, 1991-05)
      Sensing the edge of transparent film webs has always been somewhat difficult. Optical sensors typically see through the low opacity webs while pneumatic, ultrasonic and other sensors have their own sets of unique problems.
