For this purpose the.

It is also advantageous that the can be stretched. Each length of fabric itself is in rod-shaped bodies at its distances from the pockets over its length with several approximately protruding end sections on the guide wire the web width extending rods connected, 55 th sit and the end portions are releasably attached; For the purpose of this connection, the sides of the because if the ends of the z.

In these pockets you can see the plugs for replacing the rods inserted, being pulled out of the tubes at the end faces of the fabric spans fit and stretch the length of fabric and on the guides that are freely accessible from the side, to prevent lateral incidence of light. When wires get stuck. So the pipes are with like in greenhouses wide strips of fabric are used, the strips of fabric are removed and only then taken off the known measures for spreading pockets have been withdrawn. In addition to the cheaper zen or keeping the webs open and their production and assembly costs leads to the invention unusable because usual shading 65 proposal according to the invention with the further advantage that panels made of coarse-meshed fabric with less in the suspension elements are interchangeable and for neren strength exist.
