<p>The cover is used for making decorative concrete plates. The visible side surface pattern is exposed by direct washing and the plate held by contacting cover plates. The changeover from the treated to the untreated surface has a sharp boundary. A transverse member (3) of the press is held above the plate (14) on the plate washing arrangement. The plate is held between cover plates (13, 15) connected by supports to the transverse member. The cover plates have sealing profiles (16) with lip edges which contact the concrete plate. The cover plates are pressed against the plate sides.</p> |
