All-air web guide for high tension applications

The all-air RDG-5 from Coast Controls is a web guide ideal for higher tension applications such as business forms or other strong webs run in widths up to 26 inches. Requiring no electrical controls or wiring, this self-contained web guide is easy to install and simple to operate, says the company. The all-air unit, powered entirely by low-pressure, plant-supplied air (3 to 6 psi), consists of a rugged anodized aluminum frame, guiding rollers, air-actuation cylinder, and a friction-free servo controller backed by a 10-year warranty. Steering stability is provided by a three-point suspension system  incorporating two cam followers with a single pivot point. Self-cleaning pneumatic edge detectors are effective with all opaque and transparent webs, including paper, film, foil and nonwoven materials.
