A Method For Manufacturing A Ceramic Roof Tile, As Well As Roof Tile Provided With A Solar Heat Receiving Panel And Hot Water System Provided With Such Roof Tiles

摘要

When a roof tile provided with a hole is manufactured, first a non-cured composition 11 is fed between two facing mold surfaces 13b and 15b of two mold halves 13 and 15 after which the two mold halves are brought together.;The mold surface 13b of one of the two mold halves 13 is provided with a bulge 17 which has a thickness 19 that is smaller than the distance 21 between the two mold surfaces 13b and 15b at the location of this bulge in the state of the mold halves brought together. As a result, the roof tile obtains a thin part 23 at the location of this bulge 17. ;After the pressing operation the two mold halves 13 and 15 are taken apart and the composition 11 is cured. Once the roof tile 1 has cured, the thin part 23 is broken away from the roof tile and in this manner the hole 5 in the roof tile is formed.
