Even heat transfer

Today it was a terrible day to travel.  Due to an autumn storm I got rebooked and delayed. This prevented me from getting some work done on the corrugator this afternoon, so I’m using the time wisely to talk about another parallelism challenge or better put ‘controlled heat transfer’. It is very important that anContinue reading “Even heat transfer”

Even glue application

 One of the hidden problems in corrugators are uneven glue application along the width and even sometimes in machine direction. Let’s concentrate here on the doublebacker glue machines. Luckily there is such thing as a wet film glue metering gauge that helps you checking the evenness of the glue application. The instrument is simple andContinue reading “Even glue application”

It all starts with parallelism.

The ideal we want to get in corrugating are  flat sheets, no delamination, no wash-boarding and no honeycomb. To obtain above one has to have a corrugator which is in a perfect state. And this has nothing to do with the age of a corrugator but all to do with maintenance. People spend millions onContinue reading “It all starts with parallelism.”
