摘要

A method and an apparatus for measuring the compression strength, elasticity, hardness, thickness or the like property of a moving web, such as a mineral wool web, moving on a supporting base. The measuring is carried out by means of a measuring unit (10) including a pressure member or measuring head (76, 77), disposed above the web, which measuring unit during the measurement is moved at the same velocity as the web in the direction of the motion of the web. The actual measuring is carried out by pressing the pressure member or measuring head (76, 77) during the measurement against the moving web so that the web is compressed against the base (14) supporting it.
