There are two basic guide roller control methods: the centerpivot method and the end pivot method. Nireco, based on many years of experience with EPC technology, hasselected the optimal guide roller mechanism for the web material, width, tension, amount of web correction, speed,as well as the machine installation conditions. We offer these roller mechanisms to our customers.Center-pivot guide roller mechanism (GCD model)End-pivot guide roller mechanism (GED model)The guide roller mechanism on a center pivot is designed so that the center of the web plane extension on the guide roller inlet sideis the center of rotation. This guide roller system is used for web grades that can suffer permanent deformation or wrinkles when adifference in tension arises between both edges, i.e. non-expansion paper, newspaper, coated paper, metal, foil, cellulose, acetate,and brittle plastics.The guide roll mechanism based in an end pivot is available with one, two or three rollers. The number of rollers is selected accordingto the place of use. This guide roller mechanism is used for webs that are expandable and easily absorb a difference in tensionbetween both edges, i.e. cellophane, vinyl and polyethylene. It has the advantage of relatively easy installation in the middle of a line.
