Guide roller mechanism (Electric type)

Guide roller mechanism (Electric type)

Overview

The guide roller mechanism is used to correct the meandering of the traveling web. The guide roller mechanism is available as either a center-pivot system or an end-pivot system.

Feature

NIRECO provides the guide roller mechanism suited to the requirements of the web quality, width, tension, correction quality and speed and installation conditions by applying its extensive

Center-pivot system(LCD)

The center of rotation is the center of the planar extending surface of the web on the side where it enters the guide roller. This method may be applied for webs which are likely to break or have a permanent distortion due to the tension difference between both edges of the web, i.e., non-elastic materials such as paper, newsprint paper, coating paper, metal, foil, cellulose, acetate, fragile plastics, etc.

End-pivot system(LED)

The end pivot system comes in two forms: the dual-roller S-wrap type and the single-roller 90°-wrap type. The dual-roller S-wrap end-pivot system is used in the middle of the web line, while the single-roller 90°-wrap end pivot system is installed at the point where the web makes a 90-degree change in direction.
