Unwinding Web Guide

Max load 5,000 pounds (2268 kg)

This cantilevered Shifting Roll Stand (SRS2), with 1.0-inch or 1.5-inch race rods on a dual raceway assembly, accurately unwinds various web widths and can support a load up to 5,000 lbs. (2268 kg). The operator can maintain total control of the web’s tension and alignment into the converting/printing process.

A 6-inch diameter air cylinder with a 4-inch to 12-inch stroke powers the system.

Each system features Montalvo tension control components and a continuous leaf core shaft.

A shifting idler roller is standard with all Unwind Stands to maintain a proper web plane through the sensor.

These compact unwind systems are perfect for:
pharmaceutical • medical • food packaging • label • other applications where proper web alignment is crucial

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.
