“The Case for Precision Grinding of Calender Rolls on Linerboard Machines”

Thu, Jan 21, 2021 - 2:00 PM (EDT)

Do you really need Precision ground calender rolls to make linerboard? After all, it is not fine paper with all those demanding print quality tests. The answer is a resounding YES. Boxes are printed, so print quality is necessary in the form of consistent smoothness and caliper over time, strength is always critical and the board has to run well over the winder and on the corrugator. Precision ground calender rolls are critical in meeting all these demands. And they should meet these demands for longer periods of time between changes when ground correctly. It can all add up to significant ROI on your calender roll service when done right. Join us for our upcoming webinar on what you should be looking for in your linerboard machine calender roll grinding and service provider. The webinar is free but fills up fast, so please register today. We look forward to speaking with you.

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.
