Web Guiding and Spreading
Web guiding and spreading are two elements of web control that are used in web-producing processes. On paper and board machines, several fabric loops require web control to keep them running correctly on the machine. Web control is also used on the sheet after it has been dried to ensure the success of dry end and winder operations. This module will discuss web guiding first, and then web spreading.
