Roller for measuring evenness

摘要

Device comprises a cylindrical roller (1) with a tubular body (12) along which a number of meters are mounted. Each comprises a sensor (2) mounted in a hollow housing (3) within the thickness of the tubular body. Each housing is closed by a hollow cover (5) the bottom of which is a thin wall through which surface deformations are detected. A socket is embedded without any play in the housing and forms a flush surface with the thin wall.
