Abstract

To manufacture warp-free corrugated fibreboard, apparatus includes capacitive probes (26) adjacent each travelling web (6a, 7, 8) to monitor moisture content before and after combining. Each probe (26) has multiple electrodes (34) in co-planar configuration parallel to the web and a ceramic coating (38) which has its outer face (39) in continuous contact with the travelling web (6a, 7, 8) giving a consistent spacing between the electrodes and the web. The gap between the electrodes (34) is such that the capacitance of the probe is sensitive to variations in the moisture content of only the nearer web. Control means (50) coupled to the probes (26) and moisture adjustment means (13, 15, 24) compares the monitored moisture contents of the webs with pre-determined set points and/or other moisture contents and actuates the moisture adjustment means (13, 15, 24) of either web as required.
