Abstract (en)
[origin: WO0142579A1] The present invention relates to a partially rigid section obtained from a sheet (1) by notching the same in the crosswise direction and in positions close to one another and by bending it along longitudinal lines so that a central, longitudinal, continuous ribbing is formed. The section has a cross section like a double U with two vertical flanges connected to each other centrally and having a continuous squeezed bending (5). The top plan view of the section shows the crosswise notches which extend from the base of the central, vertical squeezed bending and are symmetric with respect to such bending and rise along the vertical side flanges. The section may also show a curved shape, with the side flanges being not necessarily parallel to each other, and may be provided with longitudinal slots both in the base flange and in the side flanges. In any case, however, the section always has a longitudinal continuous bending.
