Thinking Thin?

Presented by David R. Roisum, Finishing Technologies, Inc.

Markets drive us to ever thinner webs to reduce material costs and waste going to the landfill. The challenges for running a lighter basis weight or thinner caliper are at least as difficult for web handling as they are for web manufacturing. However, these challenges may not be as familiar as more commonly known machine limitations such as width or speed. Because they are not as familiar, they may catch us off guard. The challenges described in this paper include: wrinkling, air entrainment, tension control, roller design, problems associated with profile variations and others.
