  • Device for inspecting front and back surfaces of a strip material and method thereof
    Patent number: 8613225
    Abstract: In an inspection device for inspecting front and back surfaces of a strip material rolled by a rolling machine, both ends of the strip material along a longitudinal direction of the strip material are claimed by two pairs of clamping devices and the front surface of the back surface of the strip material is pressed at an optional position between the two pairs of the clamping devices by at least one pressing device. Thus, after clamping the strip material, the two pairs of the clamping devices are not displaced along the longitudinal direction of the strip material. A function for applying tensile stress to the strip material and a function for clamping the strip material are individually and separately provided so that the inspection device can be simplified. By pressing the strip material at a point between the two pairs of the clamping devices, at least one of pressing devices can be down sized. It is superior in view of an economical reason.
