Abstract (en)
[origin: EP0125369A2] Known artificial thatches for constructing a roof covering are made in the form of tubes with a constant diameter over their entire length and with a smooth outer wall. As a result of this design, difficulties arise when covering the roof, since the artificial thatches do not possess any conicity like natural reed. Moreover, the known thatches have a small wettable surface, so that a thicker layer of thatch is required to absorb temporarily the rainwater falling on the roof covering. In order to achieve easier processing and a larger effective wetting surface, the artificial thatch has a spiral-shaped cross section with overlapping longitudinal edges and is provided on its outside with left-hand ribbing. <IMAGE>
