Abstract (en)
[origin: EP2133574A2] The spatial protective screen comprises radially arranged support rods (1) that are formed as multiple flat profiles (3) wounded over the high edges. The concentric grating rings (2) are firmly connected with the support rods. The sections (5) are formed from the plane of the flat profile, where the sections are placed between an inner end (4) and an outer end (6) of the support rods. An independent claim is included for a method for producing a spatial protective screen for propellers.
