Abstract (en)
[origin: EP0721806A1] The rigid belt (1) changes from the horizontal to a 10 deg. downward slope at a roller (3) under a set of rollers (10-12) on oscillating arms (13-15) which cause an envelope to be flexed in transit. The final roller (12) rests on the slope and is lifted through a distance dependent on the thickness and rigidity of the envelope. An e.g. photoelectric detector (30) determines whether the difference between this distance and the thickness of the envelope exceeds a predetermined threshold. Further photocells (31,32) detect the advance of the envelope and compare its thickness with a predetermined threshold (e.g. 5 mm).
