Crescent formers and the like are the most nearly closed forming sections ever designed for paper machines. However, even they (don't even need to mention Fourdriniers) are still subject to the vagaries of the atmosphere. Why? Why can't we build a pressurized Fourdrinier? We think we are doing something with fancy foils, vacuum boxes and so forth, but all the air we suck through the wire comes to the wire from anywhere scientific principles say it can.…See More
Those of us used to dealing with physical items, and I'll throw paper scientists, mechanical engineers and chemical engineers into this basket, often take controls, control schemes and control programs for granted. This is a mistake. Do a Pareto analysis of your major causes of downtime, and I'll suspect electrons of one use or another rank high on the list. And we are content with this.…See More
In the past, we have shared our vision of "printing" a new paper machine in place rather than fabricating it elsewhere and moving the pieces to the erection site and assembling them. We see this first happening with machine frames, and perhaps first with dryer frames. Of course, by "printing" we mean Additive Manufacturing or 3-D Printing. For more, click here...See More
