ABSTRACT:
The hardness of cigarettes which move in a direction at right angles to their axes is measured with one or more pivotable levers which rest on the moving cigarettes to elastically deform the adjacent portions of the cigarettes. The extent of elastic deformation is measured and the results of the measurements are used to regulate the operation of a cigarette rod making or filter tipping machine so as to ensure that the hardness of cigarettes will match an optimum value.
