The guide roller mechanismis available as either a center-pivot system or an end-pivot system. NIRECO provides the guide roller mechanismsuited to the requirements of the web quality, width, tension, correction quality and speed and installationconditions by applying its extensive experience with EPC technologies.Center-pivot guide roller mechanism (LCD series)End-pivot guide roller mechanism (LED series)The center of rotation is the center of the planar extending surface of the web on the side where it enters the guide roller. Thismethod may be applied for webs which are likely to break or have a permanent distortion due to the tension difference betweenboth edges of the web, i.e., non-elastic materials such as paper, newsprint paper, coating paper, metal, foil, cellulose, acetate,fragile plastics, etc.This method may use 1, 2, or 3 rollers, and will be selected depending on the location where it will be used. It is generally usedunder light loads, to control elastic webs such as cellophane, vinyl, or polyethylene, or when handling webs that will easilyabsorb changes in tension at either end of the web. In addition, the end-pivot method can easily be installed in the middle of theproduction line.
