Abstract (en)

[origin: EP1612342A2] the honeycomb brick (10) has several through parallel holes (11) separated from one another by webs (15) wherein the wall thickness of the webs between neighbouring holes varies constantly in the direction of the parallel aligned axes of the holes and where necessary decreases to zero so that apertures are produced transversely to the axes. The wall thickness can fluctuate between 0 and 15 mm. Independent claim describes mouthpiece for worm press for manufacturing honeycomb tiles where some of the cores are mounted rotatable on the core rods and have an outer contour deviating from a central circular shape in at least one cross sectional plane perpendicular to the rotational axis.
