Seamless belts with freely configurable dimensions

The new line of Zeroseam belts is manufactured using a mouldless production process developed by Nitta. It allows for manufacturing rubber covered endless belts without joint, but with freely configurable length according to customer specifications. This is an advantage over the existing lineup of seamless belts, which is limited by available production sizes and surface materials.

“The new production process enables us to use a proprietary rubber compound, which has the best abrasion resistant properties on the market, in combination with the advantages of truly endless belts,“ explained Sebastian Vossmann, Area Sales Manager of Nitta Europe.

Due to its seamless structure, the Zeroseam belt offers high flexibility, even under low temperature conditions. The belt consists of a structured rubber surface and a polyamide fabric and has a special cord as its tension member. The surface material of structured rubber, possessing high grip and high abrasion resistance, is produced according to Nitta’s in house formulation. It is a variation of the rubber compound used in Nitta Polybelt and Polysprint lines. These features are for instance utilized in the tube winding industry, with high flexibility and grip lowering the necessary machine power and allowing for extended lifetime of the belt.

For its launch, Zeroseam belts are available in three configurations with different thickness and tension classes, with more belt types under development. Vossmann said: “We are developing additional products in the Zeroseam line including variations of material and surface structure, in order to introduce the product line to more industries and applications. There are many possibilities to explore.”

Apart from industrial belting, Nitta manufactures conveyor systems, plastic hoses and tubing, engineered rubber products, air filtration systems, industrial wipers and mechatronic sensor systems. These products are used in many industry sectors including logistics, paper processing and printing, banking automation, textile and other industry applications.
