Abstract (en)
A method and apparatus for casting concrete products by means of continuous slide casting so that concrete is extruded onto a bed (4), into a space between the bed and a mold, by means of a feeding member or members of a slide casting device travelling along the bed, the mass is compacted, and recesses are pressed onto the surface of the product by means of a roller and/or an endless belt (12) provided with protrusions. The recesses are at least partly discontinuous in the direction of the casting, and they are pressed into the upper surface of the slab at the latest during the compacting implemented following the feeding member or members, before the mix has been fully compacted. <IMAGE>
