Patent ID: 7654161

Claim:
A method of inspection of a rolled band, wherein a band sample (M) is inspected on a first face and then turned over for the inspection of a second face, said band sample (M) having a substantially rectangular shape centred on a longitudinal axis O, with two transversal ends spaced apart from one another by the length of the band sample, characterised in that, by running parallel to its longitudinal axis, the band sample (M) is brought between two spaced apart grips ( 6 , 6 ′) ( 7 , 7 ′) which are clamped respectively on each transversal end (M 1 , M 2 ) of the sample (M), the two grips ( 6 , 6 ′) ( 7 , 7 ′) are spaced apart longitudinally from one another so as to stretch the sample (M) for visual inspection of a first face, then the sample is turned over by simultaneous rotation the two grips ( 6 , 6 ′) ( 7 , 7 ′) around the longitudinal axis O, while holding the tension applied, so as to proceed to the inspection of the second face.
