Paper Machine Adjustable Drives

Sectional drive technology has evolved over the years and advancements in drive and motor designs are continuously being made. Innovations have allowed for increasingly higher machine speeds and production rates. Yet, for all of the advancements in technology, the purpose of sectional drive systems remains the same. That is to give the papermaker a means of controlling the speed and tension of the paper web as it is transferred from one section to another. AC sectional drives are most common on newer machines because of the durability, energy efficiency and affordability of AC motors. This module covers the purpose, types, and operation of paper machine adjustable drives.
