Abstract (en)
[origin: EP0467217A1] In the card of ceramic material for building up permeable structures, the card (1) has three rows of holes extending parallel to one another and arranged symmetrically in relation to the axes of symmetry. Three recesses (3, 4, 5) of differing length are arranged between the rows of holes. The recesses intersect the card edge (10,11), the longest (3) and one of the two shorter (4,5) opening out at the same card edge (10) and the shortest (5) being opposite the second longest (4). The webs (6, 6a) remaining between the recesses (4,5) and between the recess (3) and the card edge (11) have a length of 25% +/- 0 to 6% in relation to the length of the card 1 determined by the direction of the rows of holes. <IMAGE>
