Doctors, or scrapers, are used to perform a variety of functions. For example, in papermaking, depending on machine position a doctor may be required to remove water, clean the roll, remove the sheet, direct the sheet, or some combination of these functions. Proper blade design must take all of these factors into account, in addition to many others.
Essco combines its process knowledge with its engineering and manufacturing capabilities to meet specific application requirements. It is this solutions-based approach that has earned Essco the trust of customers globally. Many Essco designers have worked in paper mills alongside millwrights and have come to Essco from previous positions in the industry. This experience allows Essco to design doctor systems that are easy to install and maintain, as well as deliver high performance and long-term reliability.
