Abstract

1. A device for monitoring the moving surface of a continuous conveyor comprising at least one zone in which said moving surface is not used for conveying and in which the used side of the elements of which it is formed moves in its plane, characterised by the fact that it comprises at least one proximity sensor (4) disposed in said zone opposite said moving surface (1) and a logic circuit (15) which releases an error signal when triggered by said sensor (4).
