Abstract
In the case of a measuring roller for determining flatness deviations when handling material in strip form, for example when rolling metal strip, the stress distribution is measured over the width of the strip with the aid of piezoelectric sensors, which are arranged in longitudinal recesses of a solid roller at a distance from the casing surface and are wedged there

-14. (canceled)
A solid roller for detecting flatness deviations in a material, said material being in strip form, said roller comprising:
- a solid, one-niece body;
- a first end face:
- a second end face;
- a plurality of parallel bores extending fully encompassed in said body from one of said first or second end faces, and axially with respect to an axis of said solid roller;
- and
- a plurality of sensors provided in said plurality of parallel bores, at least one of said plurality of sensors being axially accessible by having been introduced into one of said plurality of parallel bores from one of said first or second end faces.
(canceled)
A roller for detecting flatness deviations in a material, said material being in strip form, said roller comprising:
- a one-piece body having a continuous cylindrical outer surface;
- a plurality of openings completely enclosed by the one-piece body;
- and
- a plurality of sensors provided in said plurality of openings.
A roller for detecting flatness deviations in a material, said material being in strip form, said roller comprising:
- an axis;
- a plurality of first openings parallel to the axis of the roller;
- a second opening parallel to the plurality of axial openings;
- a plurality of third openings connecting said plurality of first openings and said second opening;
- a plurality of sensors received within said plurality of first openings;
- and
- a plurality of sensor cables coupled to said plurality of sensors, wherein said plurality of sensor cables are received in said plurality of first openings, said second opening, and said plurality of third openings.
