AIMCAL R2R 2018 USA Short Courses
Optional short courses offer an excellent opportunity to further your knowledge on various topics of interest in the R2R processes. You do not have to be registered for the full conference in order to participate in one or more short courses. Those registered only for short courses are welcome to attend the Monday evening Welcome and Tabletop Exhibition. An additional fee for each course is required when registering for the short course classes.

The slot die approach provides many benefits, such as higher line speed capability and greater coat weight uniformity. To realize these benefits, the coating system as a whole must be designed to exacting tolerances based of the rheological characteristics of the fluid. The slot die can then achieve defect-free coatings with increased production speeds, positive coat weight control, controlled cross-web distribution and improved waste management.
This class will cover:
Rheology is a fundamental requirement of slot die coating technology. The study of fluid flow provides the basis for equipment design and process development. Shear rate versus viscosity data will be explained and basic formulas will be presented for understanding.
A slot die fluid coating system consists of more than the slot die. A variety of equipment is required for precision coating such as positioners, backing rolls and other ancillary equipment depending upon your substrate and application. These components will be highlighted.
When it comes to slot die coating, understanding the process and the desired outcomes is central to developing a fluid coated product. Slot die fundamentals, limitations of slot die technology and various types of applications will be presented. An understanding of statistical process window development will also be provided.
There are multiple ways to utilize a slot die for fluid coating. Both direct and indirect methods will be presented including curtain coating, lane coating, intermittent coating and tensioned web over slot die (TWOSD) applications.
Coating Defects and Resolutions
Common coating defects and the appropriate troubleshooting plan will be provided.

Wrinkling may be the number one cause of waste, delay and customer complaint in our industries. Find out why your web wrinkles and what can be done to eliminate them.
Why do wrinkles occur?
How do you diagnose the distinct types of wrinkles?
What factors influence each type of wrinkle?
How can wrinkles be quantified and predicted?
Spreading is one way to treat wrinkles, often as a last resort when all else fails. Find out which spreaders will work with your web and wrinkle type.
What are the dozen options for spreading and flattening?
Why does web caliper and web modulus determine which spreader might be best for your application?
Which spreaders can be adjusted and how do you adjust them?
Why do spreaders fail to spread and even cause wrinkles?
These courses are taught by world-renowned web handling expert Dr David Roisum.
This material is excerpted from his award winning and trademarked Web101 class that has been taken by about 5,000 students.

This short course will cover several areas important to delivering high quality fluids to a coating operation, including understanding the important variables for good mixing, estimating mix times, measuring key variables for good coating performance, and using statistical process control for solution preparation.

The last stage of many R2R processes is the production of a wound roll. Many operations struggle to achieve adequate and consistent roll quality, and end up with additional costs from scrap, customer complaints, loss of business and inability to sell into demanding markets. This course will explain the contributions of web material, equipment and conditions to winding problems. Delegates will learn about the causes of roll defects and their solutions. This will enable improvements to wound rolls and bring business benefits.
The instructor is Dr Dilwyn P Jones, who has 34 years’ experience of web handling and winding. He has presented courses in-house to several companies Europe-wide, as well as through AIMCAL at conferences and schools since 2004. He consults on web handling, plastic film technology and applications, and maintains a keen interest in scientific progress in the area, especially modelling. He will review the well-known fundamentals of winding, but also add in new material relevant to current products and processes.

Reducing flexible packaging industry annual losses from static electricity of 1% to 4% exceeds $200M in North America and $1B worldwide as the worldwide market is projected to exceed $100B USD in 2020. Static causes injuries and losses including igniting solvent vapors, shocking operators, causing sheets to stick together, attracting dust and debris to finished products, and causing logic error in machine control systems. Our AIMCAL Static Control Short Course reviews the major sources of static charging for moving films, demonstrates techniques for measuring static, and discusses methods for controlling static.
With this foundation, we learn static control methods for Roll-to-Roll manufacturing processes. After a brief overview of engineering principles, we review “best practice” static control for production operations including solvent coaters, corona treaters, nip rollers, lamination processes, winding rolls, and unwinding rolls. Included are the special static risks and counter-measures for metallized webs.
I encourage questions and comments through-out the presentation.
