Title:
EQUIPMENT AND METHOD FOR INSPECTING FRONT AND BACK SIDES OF STRIP
Document Type and Number:
WIPO Patent Application WO/2010/044165
Kind Code:
A1
Abstract:
Disclose is equipment for inspecting the front and back sides of a strip rolled by a rolling machine. Two sets of grippers grip the strip on the both sides in the longitudinal direction, and the front or back side of the strip is pressed at an arbitrary position between the two sets of grippers so that the two sets of grippers do not displace in the longitudinal direction of the strip after the strip is gripped. The inspection equipment is simplified by separating tension setting function and grip function, and at least one pressing device is made compact by pressing the strip between the two sets of grippers. The inspection equipment has excellent cost performance and is highly safe and reliable, and in the equipment, tension can be set with high precision and the risk of breaking the strip is reduced by minimizing variation of tension for a set tension at the time of inspecting the front and back sides of a strip. Furthermore, the inspection equipment corrects warp in the width direction of the strip and suppresses creasing when the strip is gripped by the gripper.
