Abstract

Process for mfg. ceramic bricks or titles, where a ceramic mass is fed through a die plate possessing a cavity corresponding with two tiles joined by webs, and the extruded strand is cut to the desired lengths followed by baking, after which the webs are broken to separate the two tiles. The novelty is that during the drawing or extrusion, at least one groove is formed at the transition zone between the webs and the tiles, to form a low strength region, and force is rapidly applied in two opposite directions, both at 90 degrees to the direction of the webs, so that the latter break in the weak zones formed by the grooves. The pref. device for breaking the webs is included in the claims. Ensures that the webs are broken at their ends so that rough projections do not remain on the titles and interfere with transport or laying.
