3-Position Cantilevered Unwind System

Turnkey Solutions

A multi-spindle, turnkey, unwind system featuring independent web guiding controls, Open-Loop tension controls, and end of roll monitoring sensors for filter and mask-making production.

This open-loop cantilevered Triple Shifting Unwind Stand (SRS1-R10-8-U-C) with linear raceways to accurately unwind various narrow webs with total control of the web’s tension and alignment into the converting/printing process.

Features: All-Air Servo Controller, Ultrasonic Sensor, Montalvo tension control components, and a continuous leaf core shaft. Framework and idler rollers are aluminum.

At least one fixed idler roller is attached to – and moves in unison with the unwind stand to keep the material on a constant plane through the air-flow sensor as the diameter of the unwinding roll decreases.
The air-flow sensor mounts to a stationary part of the machine-independent of the shifting stand and does not move during guiding.
