Abstract
The invention relates to a roll (1) for measuring the flatness of a band (M) comprising a tubular body (12) with a cylindrical external face (11) and a number of sensors each consisting of a feeler (2) mounted in a housing (3) provided in a recess in the thickness of the tubular body (12) and closed by a protection wall (50) whose deformations are measured by the feeler (2).According to the invention, each housing (3) is closed by a hollow piece in the shape of a lid (5) comprising a bottom made of an elastically deformable thin wall (50) and a peripheral part in the form of a bushing (53) encased without any clearance in the housing (3) and forming an embedding foot for the thin wall (50).
