A looper for measuring a wedge proportion of a longitudinal pull present within a strip in a longitudinal direction of the strip, wherein the wedge proportion is present across a width of the strip, has a looper shaft and pivot arms each having a first end and a second end, wherein the first ends are connected to the looper shaft. A continuous looper roll extends across the width of the strip and is supported on the second ends of the pivot arms, wherein the looper roll is adjusted relative to the strip by rotation of the looper shaft. Each pivot arm has a looper shaft arm, a looper roll arm, and a joint connecting the looper shaft arm and the looper roll arm to one another. A dynamometer is connected to each pivot arm, wherein the joints of the pivot arms deflect a return force, exerted by the strip onto the looper roll and corresponding to the longitudinal pull, onto the dynamometers, respectively.
