Description jOÓÖlI Use. invention concerns a device according to the preamble of patent claim 1 as well as a ptethod according to the preamble of patent claim 9. f©062|; in the manufacture of concrete roofing tiles by the extrusion press method, a fresh concrete layer is applied as m endless band on a line of abetting pallets: of equal length, delivered at a constant speed, which is formed on the top: side: by moulding tools into the typical surface contour of concrete roofing tiles. The continuously applied fresh conoreie layer is then sliced in a slicing Station at the end: of each pallet by means of a cutting fool designed as i: knife., so that each pallet carries a single ifioftidipg, or a concrete roofing tile blank in the present: case. The: concrete: roofing file blanfcfs then enred inp drying chamber, lying on its pallet, and is then provided with a surface coating. A method and a device for the: niann&amp;tcture of such concrete roofisg tiles are described in DE 35 22 Mb A i and AT 400 120 8. 3ÖÖÖ3J In order to provide a sufficient tightness to driving rain for roofs covered with corser etc roofing ides of Ée nforethehSfoued hind, it is necessary for the concrete roofing tiles adjacent to each other id a fidgereaves line to overlap. The overlapping length will depend on the particular roof gradient, t.e., the overlapping can be chosen less for a very sirong roof gradient than for a low roof gfadienfi {6804| The use of these concrete roofing tiles for roofs with a gradient of less than 22° - which includes In particular nouresidenfiai commercial feulldlngs,-is; problematical Since a very large overlapping length of the roofing tiles is required, it is necessary today &amp; very large number of parallel roofing file rows. The large consumption of roofing tiles and the eonstruefion of a roof batten structure adapted to the mtmber of roofing tile rows increase the material and labour costs cöhslrforabíy. Therefore:, commercial buildings are often roofod with cheaper and lighter roofing materials, sach as metal sheeting or fils® oement panels. Í06ö5| Yet in order to use concrete roofh tg files m these buiMtegs with m drayfoacks, the industry has begun to provide a water battier on the top side ofthe concrete roofing tiles in the region of their head margin, which prevents fire penetration of driving rein. In this way, the high material and labour costs can be avoided. P8S6f Methods and devices are known from DE IS 12 456 A1 and DE 25 08 551 Al which ate suitable for providing concrete roofing tile bfonfis lying on their pallets with a water barrier, in both methods, at first the water barrier is formed Rom a separately prepared fresh concreto, which is then pressed down on the top side of the concrete roofing tile blank in foe region of the heat margin, f0Ö0T| fufthermore, devices are know« with which roofing files Pia be matte Ihat: have a transversely momhg shoulder at one end f<jB 70f 172, Fig. :13 to 15, and HR §64 fiit) A, Fig. 3 to 73, JR-A-57 12b hi 4 discloses a device and a method lor the making of a water harrier in a not yet eared roofing tie a® orbing to fire preamble of claims 1 and 9 and the problem to be solved by the ftryepfion Is to create g method and a device for the marvulacture of concrete roofing tiles provided with water harfiers that is suitable for rather Mp production output and at the same time guarantees an improved and jbpg-iastlng fonetiouality of the water barrier. {Ô008| The problem is szíved according to the features of patent claims 1 or 9, {$8091 Titas, the iovenfion mnmm a device and a method for the making of water harriers hr roofing tile blanks that are not yet solidified.
