DESIGN OF EXPERIMENT (DOE)

Thu, July 29, 2021 - 2:00 PM (EDT)

Today’s manufacturing processes are increasing in size and complexity every day. As a result, the number of variables that can influence a process grows larger. Sometimes, a variable is not even known to have a significant effect until a proper analysis has been done. A design of experiment, or DOE, is a critical component of process improvement. Using statistical analysis and 6-Sigma methods, a design of experiment can improve process control and provide the necessary knowledge to control variables and produce quality products every day. This webinar discusses the basic principles of a DOE and how Precision Roll Grinders uses DOEs to verify and improve a system’s performance and continually add value to our customers’ production line.

Why Precision Grinding of Paper Machine Press Rolls is Critical

Thu, June 3, 2021 - 2:00 PM (EDT)
Why would you need a precision grind on a paper machine press roll?  After all, isn't it a soft cover that is going to deflect by design anyway?  Proper roundness and shape on press rolls is critical for your press section to run at optimum capacity.  Precision roundness prevents short-term machine-direction moisture variation and excess wear on your press roll bearings, frames, clothing and roll covers.  Precision shape provides the best cross-directional moisture profile and keeps press clothing performing as designed.  Join us for a short webinar outlining the necessity of precision roll grinding in your paper machine press section.  The webinar is free, but may fill up fast, so please register today.  We look forward to speaking with you.
 

Precision Roll Grinding as a High Return Investment Opportunity

How Paper Machine Calender Roll 'Barring' Hurts Your Bottom Line

Thu, Apr 22, 2021 - 2:00 PM (EDT)

When your calender rolls exhibit 'barring' or variation in roundness, it hurts your bottom line. Calender rolls that are not precision ground to roundness, shape and concentricity will quickly begin to induce variation in your product and adversely affect your product strength and appearance. With fiber costs rapidly increasing and other costs closely behind, it is more important than ever that your calenders are operating at their best. In addition, poor calender performance transfers to the end-user in the form of inconsistent printing, converting and overall performance. Please join us for a brief webinar explaining how calender roll 'barring' occurs and what can be done to eliminate it as a primary variable in your process.

Paper Machine Calenders - Precision Grinding for Optimum Performance

Thu, Jan 7, 2021 - 2:00 PM (EDT)

Roundness specifications for paper machine calender rolls should be 0.0002" or better. However, many paper machines are running calenders with rolls that are being ground to tolerances 4 or 5 times this specification. Usually it is because there is a history of producing acceptable product at these tolerances. However, are the calender stack rolls being changes 2 or 3 times more often than they should? Are there 'mystery breaks' at the dry end of the machine? Are strength test more variable than you would expect? Join us for a quick webinar outlining how proper precision grinding of calender rolls results in significant returns well beyond any additional associated costs.

SPECIALTY COATINGS

Thu, Jul 9, 2020 - 2:00 PM (EDT)

Today’s specialty coaters and laminators are always looking for new ways to run their operations more efficiently and smarter. They need to minimize material waste. And keep their lines up and running for as long as possible. This is an industry where waste reduction relies heavily on limiting/eliminating variation — like machine direction variations (sometimes called “corrugated”) and barring — through the coater or laminator, and the effects that doing so has downstream. Rolls that are not perfectly smooth — with microscopic peaks and valleys — will require the use of more production material. They’ll also create inconsistent product.
