Overview

The Guide Roll Mechanism is used to correct meandering of the traveling web. The Guide Roll Mechanism is available with the center pivot system and the end pivot system.
NIRECO provides the guide roll mechanism suited to the requirements of web material quality, width, tension, correction quality and speed and installation conditions of a machine by applying its long experience of EPC technologies.

Center pivot system

The center pivot system allows the center of the extending surface of the web on the guide roller side to be the pivot center. Installation may sometimes be difficult, but in all other regards, this is the best intermediary guide roller system.

Features:

• Excellent stability and accuracy of control;
• No negative influence on the upstream side of the guide rollers;
• The design of the center pivot system means that adjustments can be made simply by applying torsion to the web, with minimal risk of creasing.

This makes the center pivot system ideal even for paper, metal and foil webs that have a high modulus of elasticity.

Specification

End pivot system

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.
