Abstract
A deflector roll for measuring and checking the flatness of sheet metal under tension and as it passes round the roll comprises a non rotatable inner portion carrying axially spaced radial stress detectors in axially spaced measurement zones spaced by neutral zones, and a continuous rotatable outer envelope to be contacted by the sheet and to transmit the radial stresses to the detecting devices, the envelope having an axially variable flexibility such that it is less flexible in those portions which cover the measurement zones than in those portions which cover the neutral zones.
