ROLL FOR MEASURING STRIP FLATNESS WITH MEASURING BEAMS MOVING IN A STRIP-TRAVEL DIRECTION Russian patent published in 2018 - IPC B21B38/00 

FIELD: measurement; testing.

SUBSTANCE: invention relates to the field of measuring tensile stresses for determining strip flatness defects on the width of a strip. Roll contains points (3) integrated in the roll surface to measure the tensile stresses in the strip, located at different locations along the width (B) of the strip, each measurement point (3) having measuring element (4) located on the surface of the roll, which is disposed on at least one force sensor (5) measuring elements (4) being made in the form of measuring beams and at least in part of their length (l') defining the measurement length (l) have a constant width (b), and length (l'), respectively measuring length (l), of the measuring beams is at least two times, preferably at least three times width (b), measuring beams being arranged with their longitudinal direction in the direction (R) of the strip movement and oriented perpendicularly to the roll axis.

EFFECT: invention provides an improvement in the measurement accuracy.
