253951--23 - and the two still moist glass fiber layers-20 and 21-provided lower shell - placed on top and the two shells-6 and 19 - are connected to one another by applying pressure, for example by screwing them together, and the synthetic resin is allowed to harden . This creates heat in the synthetic resin itself, which accelerates the hardening of the synthetic resin, but if necessary, heat can also be supplied from outside. Before joining the two

1.

   Protective roof for tractors, consisting of essentially solid, non-deformable material, such as glass fiber reinforced polyester resin, the roof body of which is provided on its long side with tabs or the like protruding downward from the lower edge, each of which is supported by a substantially perpendicular and on the rear axle housing Strut is connected at a rigid angle, according to Patent No. 253951, characterized in that the roof body is held at a distance from one another by means of rigid spacers (23) distributed essentially over the entire roof surface and with these spacers and shells (6, 19) glued to one another. consists.

Claims

(23) consist of wooden blocks, the grain of which is substantially perpendicular to the mutually facing sides of the shells (6, 19) and that cavities (25) are provided between the individual spacers (23).

3. A method for producing a protective roof according to claim 1 or 2, characterized in that first the two roof shells (6, 26) are produced, a glass fiber layer mixed with plastic is sprayed onto one of the two, and the spacers (23) are placed on this and then another layer of glass fiber mixed with plastic is sprayed on and compressed, then a layer of glass fiber mixed with plastic is sprayed onto the second roof shell and the two roof shells are connected to one another in a known manner by applying pressure and possibly heat.
