Abstract
A method and apparatus for a calendering system is provided to allow for fine gauge adjustment of the product. The calender system has a first and second roller each having a first and second end mounted in opposed end supports. The end supports each have an inlet and an outlet in fluid communication with one or more internal passages, wherein a heat transfer medium may be circulated through the one or more internal passages. The heat transfer medium may either heat or cool the internal passages of the end supports, resulting in the respective increase or decrease in the gauge of the product.
