MEASURING ROLL FOR DETERMINING TAPE PLANE DEFECTS (OPTIONS) AND METHOD FOR DETECTING TAPE PLANE DEFECTS

摘要

1. Measuring roll for determining flatness defects of the tape and / or for determining the tape tension of the tape, in particular a metal tape, with at least one built-in measuring roll in the roll’s outer surface, which is supported by sensors, characterized in that that the measuring beam as a beam (5, 5a) measuring the tension of the tape to determine the temporal course of the tension of the tape runs essentially along the direction of the circumferential contour along one predetermined area of the circumferential contour. ! 2. Measuring roll for detecting defects in flatness of the tape (2), in particular a metal tape, with at least one built-in flatness beam (3a, 3b) embedded in the roll’s sheath, respectively, on the outer surface of the roll, which is supported by sensors (4) , and to determine the distribution of the tension voltage across the width of the tape, it runs obliquely to the axis (A) of the roll and runs, on the one hand, along one predetermined area (b) of the width, and on the other hand, along one predetermined area (U1) of the circumferential contour of the roll, characterized in that the beam measuring pl velocity (3a, 3b) contains at least one tape tension measurement beam as a reference (reference) measuring beam (5), which is also supported by sensors (4), and essentially determines the time course of the tape tension along the direction of the circumferential contour in one predetermined zone (U2) of the circumferential contour. ! 3. The measuring roll according to claim 2, characterized in that the reference (reference) measuring beam (5) and the flatness measuring beam (3a, 3b) lie essentially along the same zone of the circumferential contour (U1 = U2). ! 4.
