Manufacture of arch elements according to the KS bending process

Patent No. DE 33 22 572 C2

During the KS bending process only the arch area is plasticized by briefly heating it in a warm bath thereby making it pliable.
This is an advantage when bending circular and basket arches with straight legs since only the bended portion is heated and the profile legs remain cold. This enables us to bend PVC profiles in one piece. This eliminates welding the profile legs and the unattractive attachment from the arch to the straight piece.

With this method the profile cross section remains true to size and the cross pieces can be easily welded. The incorporation of cross-bars or posts are also no problem.

The KS bending process makes it possible to fit both white and foiled profiles perfectly to form.
