Belt Design

The belt substrate (fabric) is woven endless on looms as a tubular hose. The threads are wound in a spiral in the belt drive running direction. The belt circumference is determined by the diameter of the spirals, while the required width is obtained by slitting the hose.

To reach the required properties and dimensional stability, the belt substrate is impregnated with a specific elastomer and treated in a special thermal process. For friction-feed applications, the belts are further coated with a specific cover compound in a truly seamless manner, ensuring uniform physical properties during the entire service life. This unique manufacturing process guarantees optimal, smooth and vibration-free operation, even at high speeds. Seamless belts are available in stable, semi-stable, semi-elastic, and elastic versions.
