The invisible and innovative welt seam in the area of textile sun protection. The NonVi Twin consists of two half welts with a groove. The fabric is fed between the welt halves and sewn.naht im Bereich des textilen Sonnenschutzes. Der NonVi Twin besteht aus zwei Halbkedern mit Nut. Das Gewebe wird zwischen die Kederhälften geführt und vernäht.

The NonVi Twin is highly flexible and can be used both on the fabric shaft side and in the front profile, depending on the application.

The defined fabric tension over the entire width of the fabric prevents the fabric from “shrinking”. This creates a smooth transition that ensures a clean winding behaviour. Creases are also demonstrably minimised.

Application Areas

• Front side and fabric shaft side of textile sun protection and other hangings.

• 4-sided processing for big banners.

• Interior and exterior fabrics.

• Acrylic, screens, Soltis and other
  coated fabrics.

• Sewn onto fabric with groove.

• Special features

  • Because the NonVi Twin is bonded directly with the fabric edge, which is then completely inserted into the profile, it ensures a seamless transition from the fabric to the profile. This creates an appealing appearance without shadowing due to double plies of fabric.

  • Using the NonVi Twin means that the traditional fold is eliminated, thus reducing material costs.

  • The welt can be optimally adapted to the welt profile as it is available in various sizes.
