<p>A device is used for mfr. of frame-shaped building parts pref. skylight mounts, from (glass-fibre-) reinforced plastics, using a mould defining the inner contours of the mount. Near the upper and/or lower edge of the mould there are hinged flaps. These bear on the outer surfaces of the moulding when it has not quite hardened, and cover the entire outer surfaces of the mount. Consequently, they define, with their inner (i.e. bearing) surfaces the outer contours of the mount.</p> |
