Test roller for the measurement of the strip tension and / or the strip temperature over the bandwidth for a strip flatness regulation during rolling of strip material

摘要

Measuring roller (9) for measuring web tension and/or web temperature for web flatness control during rolling of a web material comprises a roller body (13) with peripheral channels (17) that run parallel to the axis of the roller and are alternately interrupted longitudinally, a roll cover (14) that is heat-shrunk onto the roller body, and sensors (19) inserted through the ends of the roller into the spaces defined by the channels and roll cover.
