US 7,654,161 B2 · Method and device of inspection of a rolled band

Abstract

The invention relates to a method and a device of inspection of a rolled band, wherein a band sample (M) is inspected on a first face then turned over for the inspection of a second face. According to the invention, 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 (M1, M2) of the sample (M), both grips (6, 6′) (7, 7′) are spaced apart longitudinally from one another so as to stretch the sample for visual inspection of a first face, then the sample is turned over, by simultaneous rotation of both 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, such tension being sufficient to conduct the inspection without the sample contacting a table. The invention enables, in particular, the inspection of a band at the exit of a continuous rolling line.

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 (M1, M2) 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.

An inspection device for a rolled band comprising means for sampling, on the rolled band, a band sample (M) of substantially rectangular shape with a longitudinal axis and two transversal ends (M1, M2) spaced apart by the length of the sample (M), means for holding the sample along a plane for the visual inspection of a first face, and means for turning the sample over for inspection of a second face,

characterised in that it includes two spaced apart clamping grips (6, 6′) (7, 7′) for clamping respectively the two transversal ends (M1, M2) of the sample (M), the grips being carried respectively by two platens (5, 5′) mounted rotatably around the same longitudinal axis, each in a supporting stand (3, 4), means (37) for stretching the sample (M) by spacing apart the two grips (6, 6′) (7, 7′)after clamping the ends (M1, M2) of the sample (M) for holding it along an inspection plane running through the longitudinal axis (O), and means (55, 55′) for controlling the simultaneous rotation, around the longitudinal axis O, of the two platens (5, 5′) with the grips (6, 6′) for turning the sample (M) over while holding the tension applied thereto between both grips (6, 6′) (7, 7′).
