Web Tension Control & Pneumatics:

Pneumatics ( or “air”) in web tension control is a type of force-balancing act. High pressure air is applied automatically to one side, or the other, of the diaphragm cylinder moving the cylinder shaft in the desired correction direction. The pressure is preset to match the desired operating tension. When the desired or preset tension level is achieved the cylinder pressure is neutralized and held at that point. If another upset, or change in tension is sensed, the process starts correcting all over again. Our Diaphragm Cylinder Series RDC features a nearly frictionless movement without sticking or slipping. Used in combination with our pressure regulator valve units, pneumatics offer a dancer control for web printing and converting operations in both wide and narrow web applications.

Maintaining precise tension control with electro pneumatic pressure regulators and low-inertia, low friction pneumatic cylinders, offers precise control over a wide range of tensions and web positions for all web materials, ribbons and related substrates. The pneumatic application geometry ranges from swing arm compensation units to ball screw compensators both in vertical and horizontal positions. Pneumatic tension control provides a wide range of tension adjustments not available in other mechanical systems such as torsion springs, etc.
