Truly endless

Manufactured without any splice or seam

Our endless belts are made according to a unique process – where no splice and no seam occurs! The highest application security in long-term working does beat the spliced “endless” several times.

Manufacture of fabric

From endlessly woven fibres, traction layers that are stable lengthways are manufactured to a precise length.

Gumming of fabric

The calibrated fabrics are covered and coated with raw rubber compounds.

Vulcanisation and belt coating

Each flat, timing and Poly-V belt is endlessly coated with high-quality rubbers and plastics.

Quality control/ Dispatch

Customer- and application-specific checks are carefully carried out. In some cases with certification. Prompt dispatch takes place subsequently.

Cutting/ Finishing

Under the defined tension force, the individual belts are cut, perforated, milled or even marked.

Grinding/ Milling

The belts and tapes are ground to a precise thickness across their full width.
