Abstract
The invention relates to a method and an apparatus for measuring properties of a moving web. Web properties are measured with a measuring apparatus where at least one sensor element is arranged to a rotating measuring roll. The measuring roll is in contact with the web to be measured, and the circumferential speed of the measuring roll is arranged to substantially equal the web speed, the web being substantially in non-slipping contact with the measuring roll for an arc of the rotation of the measuring roll.
