The seamless belt substrate (fabric) is manufactured endless on looms, or knitted as a tube. The threads are wound in a spiral in the belt running direction. The belt circumference is determined by the diameter of the spirals, while the required width is obtained by slitting the tube. To reach the required properties and dimensional stability, the belt substrate is coated with a specific elastomer and treated in a special thermal process. Seamless belts are available in stable, semi-stable, semi-elastic, and elastic versions.
For friction-feed applications, Habasit’s GRABBER belts are 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.
Endless woven or seamless processing belts are available in a range of belt strengths and are uniformly coated with thermoplastic materials or silicone to obtain the required properties for the specific application.
