Pneumatics

"Pneumatic solutions for the Printing and Converting Industry."

Rexroth pneumatic components play an important role in all automated printing and paper industry processes. From valves, cylinders, control units to handling systems, Rexroth products ensure reliable and consistent quality results. If you are a commercial, publications, newspaper, packaging, or label printer look at Rexroth products when consistent and reliable products are needed in your production cycle. Printing companies today using either Flexography, Offset, Gravure,or the Digital printing process look to the Rexroth name and products for reliability, reduction in down times and faster make readies. If you are a Converting company, you will also experience the same quality and performance using Rexroth components in your laminating, die cutting, coating, folding, embossing and other related converting operations. From Pre-press to Post Press operations, we are the only automation partner to offer electric drive and controls systems, pneumatics, linear motion technology, assembly systems and world wide sales and service, all from a single source.

With our library of experience and knowledge working both with the leading press manufacturers and printers around the world, we are in an excellent position to solve your many needs and answer the many questions that arise in your daily functions. Put your trust in Rexroth and let us show you how we may improve on your day to day production operations.

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 Series RDC Diaphragm Cylinder features a nearly frictionless movement without sticking or slipping. Used in combination with our pressure regulator valve units, pneumatics offers 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.
