It represents an important innovation, because it is able to bend the profile in two directions, forming an ” S ”.
It represents the last frontier of section bending machines and offers a type of curvature that the normal machines on the market cannot perform.
The bending rolls move on a vertical axis and on a linear guide system. They are also retractable, and all these features allow the special “S” processing of the profile.
This innovative machine technology allows bending empty profiles avoiding any kind of deformation. In this regard the so-called “mandrel” plays a very important role. A jointed support that, by inserting itself into the profile, accompanies the curvature while maintaining full conformity of the piece.
