摘要

This system is of the type comprising a carriage (40) which is movable on a rail (12) and bears a number of oscillating nozzles (47 and 49). According to the invention, the carriage (40) consists of: a) a first sub-assembly (A) consisting of a reversible jetting module (42) which, bearing the nozzles (47, 49), is equipped, at each of its ends, with a male hydraulic connection (65) which is capable of being connected either to a circuit (129) of water under pressure or to the following module (43); b) and a second sub-assembly (B) consisting of: b1) a module for attaching (43) and driving rotationally the nozzles, b2) a reversible module for observation and detection (44), b3) an autonomous translation module (45) consisting of at least two motorised toothed wheels (118) capable of meshing with the racks (16) of the rail. <IMAGE>
