Abstract

A device for detecting discontinuities in ceramic products such as floor tiles and wall tiles comprises one or more pairs of electrodes 3, 4 disposed vertically above and below a conveyor 1, which carries a ceramic product 2 between the pair or pairs of electrodes. A potential difference is generated between the electrodes, so that if there is a discontinuity in the ceramic product, a discharge will occur between the electrodes. <IMAGE>
