Montalvo's Torque Sensing Control System

The Montalvo Torque Sensing Control System (TSC) is a total tension control solution that delivers performance, convenience, and productivity. Simple, compact and easy to install and operate, the TSC is the latest innovation in open loop tension control. Patented technology allows easy integration into existing machines as well as new machine builds.

The TSC is ideal for applications where...

• The machine cannot accommodate load cells or retrofits (space limitations, costs, etc.).
• There are multiple web paths or web is traveling directly from unwind roll into the process.
• The web cannot be contacted after unwind by rollers or requires minimal roller contact (coating, films, foils, etc.).
• Multiple unwind stands that each require cost effective, simple control, and a simple web path (sheeters, laminators).
• Existing open-loop system, but want to improve consistency and quality of your production.
• Utilizing a PLC or similar system and want to control torque with minimal modification and effort.

1. As a roll unwinds it rotates the shaft and brake disc. When friction pads attached to the spider plate are engaged against the brake disc, this force (torque) tries to rotate the spider plate.
2. This rotation is prevented by the Torque Sensor. The force (torque) being applied to rotate the spider plate is measured by the Torque Sensor.
3. The measured torque is provided to the U4 Tension Controller and, in conjunction with a diameter measurement, calculates tension of the web, which is then displayed on a meter.
