<p>The device has a polymer or composite material film i.e. glass fiber film (4), with rot-resistant, hard and smooth surface, and rigid properties, where the film has sufficient flexibility to be rolled up in an easily transportable form. The film is formed of a single piece or reduced number of pieces for being deployed in a flat manner on a horizontal support (3) and on the entire length of an animal housing. The support is a framework that is fixed to posts (2) of the housing, or a floor of the housing. A rubber scrapper (6) has round ends matching with round edges of the film.</p> |
