1. A measuring roller for determining strip edge position and flatness of a strip-shaped material, passed over the measuring roller, comprising
a measuring roller body with a circumferential surface,
at least one first recess in the measuring roller body, the first recess having a first cross-sectional shape,
at least one beam disposed in the first recess and extending along a longitudinal axis, and
a force sensor arranged in the recess
wherein,
the beam is supported within the first recess on the force sensor, and
where the measuring roller body extends along an axis of rotation (A) and the longitudinal axis of the beam does not run parallel to the axis of rotation (A) of the measuring roller body and the longitudinal axis of the beam does not run in a plane which is perpendicular to the axis of rotation (A) of the measuring roller body, and
wherein multiple further recesses are arranged in the measuring roller body, a second force sensor being arranged in each of the further recesses, each of the further recesses having a second cross-sectional shape which is different from the first cross-sectional shape of the first recess; wherein the second cross-sectional shape of the further recess is circular; wherein the multiple further recesses are arranged in a first row of recesses and a second row of recesses, wherein the first row of recesses and the second row of recesses each extend parallel to the axis of rotation (A) of the measuring roller body and, wherein the further recesses of the first row of recesses are arranged offset to the further recesses of the second row of recesses in a direction along the axis of rotation (A) of the measuring roller body, such that when looking along the circumferential surface of the measuring roller body in a direction transverse to the axis of rotation (A) one of the further recesses of the first row of recesses is located between two adjacent further recesses of the second row of recesses.
