Abstract (en)
[origin: EP0980725A2] A strip (1) of plastically deformable material is pleated over its whole surface in a meander, esp. wave-like, zig-zag, or step-shape. Reforming of the pleat at a distance to the longitudinal edges, creates at least one flat section (3) on the strip. The section extends in parts over the length of the strip, so that water drainage channels (5) are formed between the flat section parts. The flat sections are formed esp. by folding, upsetting, or stamping, and pref. have a higher wall thickness than the remaining folded sections, esp. 1,5 to 2,5 times higher.
