The process of turning 55"
diameter parent rolls into a small enough size to be used
as paper towels and toilet paper involves rewinding as well
as cutting the paper. Given the difference in size between
the parent rolls and the finished product, the cutting
process is extensive and can generate levels of heat
which hinder equipment performance. Laun explains "In
cutting our paper logs, we use a 40-inch diameter circular
blade to saw through logs from 4" to 12" diameter at
up to 50 cuts per minute. The sawing process creates
a lot of friction and heat. Once you reach 100 degrees
Fahrenheit, the blade begins to wobble and at that point
it's unsafe to continue cutting anymore.
