2018 Academic Advisory Committee Meeting 

& Senior Design Project Presentations

Thursday, May 17, 2018

The Paper Science & Engineering Academic Advisory Committee (AAC) Meeting is an annual event held each spring.

Each year, representatives from the paper and allied industries gather with the Paper Science & Chemical Engineering faculty and staff to listen and assess the Senior Design Project Presentations and provide students with constructive feedback on their projects.  After the presentations the committee meeting begins with an update from Karyn Biasca, Department Chair, on the status of the Department where industry representatives input on curriculum is welcomed.   The AAC meeting is followed by a Luncheon for participants. 

The schedule for May 17, 2018:

8:15 am Check-in begins

9:00 am Student Presentations

10:45 am Academic Advisory Committee meeting

12:00 pm Luncheon


Senior Design Project Abstracts

Fiber Blending and Recovery System

Students: Adam Socha, Evan Page, Victor Vang, Rudy Mogden, Nick Dercks, Jon Waterman, Casey Ausloos


The purpose of this project is to convert the fiber recovery system on the UW – Stevens Point pilot paper machine from a fractionation saveall to a sidehill screen. This installment will improve fiber blending capabilities and reduce plugging issues at the current saveall by limiting its use. If successful this project will allow for the use of synthetic fibers on the machine, the ability to control fiber length distributions, and the ability to utilize broke more effectively. By piping around the stock preparation section of the machine, recovered fiber from the couch tank may be sent back to the mix chest, with the filtered whitewater being recycled back to the seal tank. The fiber recovery systems will be able to run as an either/or, with hand valves controlling which piece of equipment the couch tank flows to. Consistency meters and flowmeters will be calibrated to ensure 100% accuracy. This will allow for weight percentage of each fiber type and the length weighted average length of the blend to be easily calculated. This design will keep the fiber blend consistent throughout the machine during a run. 

Secondary Headbox Implementation


Students:  Joseph Kinscher, Justin Okruszynski, Luke Mason, Farrah Scears


The purpose of this senior capstone project is to design and implement a secondary headbox on the Mead-Wittier Pilot Fourdrinier Paper Machine located at the University of Wisconsin Stevens Point. This group consists of four senior Chemical and Paper Science Engineering students including: Joeseph Kinscher, Luke Mason, Farrah Scears, and Justin Okruszynski. The group project objective is to optimize a secondary headbox by examining the design, method, wet end process, and types of grades that can be created. This technology will be useful to the Wisconsin Institute for Sustainable Technology (WIST) to meet the demands of their customers. Implementing a secondary headbox that can produce a uniform two-layer sheet will allow WIST to manufacture new grades of paper, adding new technology and value to the current pilot paper machine. In addition, a secondary headbox will allow the paper machine to produce a wider range of basis weights to provide learning opportunities for the Paper Science and Engineering students on campus, as well as the hands-on courses WIST offers to companies in the paper industry.

Pilot Paper Machine Size Press Improvement

Students:  Colin Koffarnus, Justin Dentici, Nathan Smith


The pilot paper machine at UW-Stevens Point is a small scale Fourdrinier paper machine that is used for education and research purposes. A horizontal size press is used to apply surface sizing coatings to the base sheet. The size press currently has runnability issues that prevent it from being a reliable piece of equipment and is therefore used minimally on machine runs. The size press has safety issues that need to be addressed and a recycle system needs to be installed to allow the sizing materials to be re-used and not wasted. The side dams need to be improved, a system for two stream blending needs to be installed and a standard operating procedure needs to be created for the size press. Research was done to see how conventional size presses operate, what variables to look at when dealing with coat weight control, how to cook and deliver starch, what other types of sizing additives can be used, and what mixing technology can be used in the process.

Three goals for this project are: make the size press a safer piece of equipment, decrease the amount of lost sizing agent, or coating, during a machine run by fifty percent, and introduce five new grades to the WIST run schedule. The solutions that have been derived from talking with machine operators and research have three different combinations. The first solution would move the pond height controls to the tending side of the machine and improve the catch pan and side dams. The rubber piping that is used needs to be replaced with clear, re-enforced rubber piping. The catch pan will be re-designed to hold a larger volume of coating and be able to recycle sizing material more efficiently. The side dams would be replaced with the same material, but will be cut to fit better in the dam area and easier to take in and out. The second solution would move the pond height controls to the tending side of the machine, improve the catch pan and side dams, and install a doctor blade on the non-driven roll. The doctor blade will be installed to prevent the wrapping of the size press with the paper web thus mitigating the operators from keeping their hands out of the nip region. The third solution would move the pond height controls to the tending side of the machine, improve the catch pan and side dams, and install a metering pump on the starch supply tank. The metering pump would replace the air diaphragm pump that is currently installed, and this would allow for a more consistent flow of sizing agents, or coating, to the size press. The paper machine is also at maximum capacity for compressed air and to operate the air diaphragm pump, a separate compressor needs to be attached. The separate air compressor would not be needed with a metering pump. The end date for accomplishing one or more of these goals is May 2018.

The first solution would provide the size press with some necessary improvements at a low cost. The second solution offers the most improvements at a slightly higher cost than solution one, but far lower than solution three. Solution three offers the best improvements to the size press, but at an excessive cost. Metering pumps are expensive and will most likely require more money than the budget for the project will allow. Moving the pond height controls to the tending side and improving the catch pan and side dams are relatively inexpensive and can easily be accomplished. The doctor blade assembly will require some contractor work, but it is still relatively inexpensive to the cost of the metering pump. If funding is available, the third solution should be pursued and if funding is not available for a pump, the second solution will still provide the necessary improvements to make the size press a more versatile and functional tool for WIST and the students of the Paper Science and Engineering major at UW-Stevens Point.

Size Press Unwind

Students: Benjamin Demchik, Austen Dins, Joe Molle, Jay Tienor


The University of Wisconsin Stevens Point (UWSP) paper machine, operated by the Wisconsin Institute of Sustainable Technology (WIST), can create paper and use an in-line size press to coat it with a desired chemical agent. There is a current interest by WIST customers to add coating to pre-made rolls of paper. This requires a new mounting system that would allow a roll of paper to be coated through the in-line size press.

The purpose of this project is to design an unwind stand that will allow rolls of external paper to be run through the size press on the UWSP paper machine. Our designs will satisfy the interest of WIST's customers. Three separate designs that each have varying processes and locations have been laid out to satisfy the problem.

The appropriate next steps are to audit these designs with electrical, mechanical, and structural engineers. This would prepare WIST and UWSP for the decision of a final design and eventually fabrication and installation. Then the equipment will be tested to work out any kinks. Operators will be trained on the loading and operating processes. After this is all completed, WIST will be able to utilize the new system to add coatings to pre-made rolls of paper.
