Vanguard Tow and Tape Tension Control Systems

Precise, Consistent, Uniform Tension Control of Every Individual Tow

Inconsistent and non-uniform tension on every tow creates many negative outcomes, from manufacturing scrap to catastrophic failure of end products. Inconsistent tension amongst tows which are meant to work together to form a single product creates weak points across the end material as tension varies. Proper tension control of every tow ensures each tow’s effectiveness is maximized, creating stronger, better, higher quality end products.

The Montalvo Vanguard System (MVS)

The patented Vanguard System is Montalvo’s flagship closed loop tow and tape tension control technology system, leading the way in precise, uniform, consistent, automated tension control.

The MVS automatically controls even the slightest changes to ensure tension is automatically and always, precisely where you set it. Maximize your productivity and profitability!

The Montalvo Vanguard System is comprised of three major portions – Tension Control, Tension Measurement, and Torque Control for a total closed loop tension control system.
