PosiLeno® brings value added to Leno weaving –
PTFE-coated conveyor belts

As an innovative technology, leno weaving is opening up new opportunities and new application possibilities all the time - and one example is where conveyor belts made from polytetrafluorethylene (PTFE) for the textile industry are concerned. The requirements placed on precision and production quality here are very stringent. Which is why PosiLeno® from Groz-Beckert is the right choice.

The field of application


PTFE conveyor belts are used for drying, fixing and laminating. They are suited to belt speeds of up to 60 m/min and roller diameters of 90 mm upwards. PTFE-coated, open-mesh leno fabrics made from aramid (warp) and fiberglass (weft) are perfect as textiles. Mesh widths of 1x1, 2x2, 4x4 or 5x5 are available for selection.

The properties of the dimensionally stable and tear-resistant leno fabric combine perfectly with the advantages of PTFE coating:

  • Temperature-resistant with low thermal expansion
  • Chemical resistant
  • Physiologically safe
  • Anti-adhesive and sliding properties

Leno system and leno healds - the perfect combination


You can find just the right products for this application in the Groz-Beckert portfolio! Special leno healds with C or J shaped eyelets open at the side are available, and their proven combination of synthetic lifting healds and steel half-healds guarantee optimal performance. Moreover, the gentle movements of the PosiLeno® system make it possible to process the aramid fibre warp yarn optimally.
