Title: Scanner with interior gauging head and combined dust and drive belt

Abstract: A scanner for moving sheet material such as a paper-making machine provides the gauging heads which measure parameters such as basis weight and moisture entirely inside an enclosed tubular beam. Each gauging head is driven by a single belt which both drives the gauging head in a cross direction perpendicular to the moving sheet direction and provides for dust and dirt protection by covering a slot in the beam, except where the gauging head is located.
