Abstract
The invention refers to a process for measuring spacing at a paper machine headbox. It is primarily characterized by constant magnetic fields being generated at the headbox slice gap area, the intensity of these fields being measured and these measurements being used to determine the gap between the individual lips. The invention also refers to a measuring device to determine spacing in the headbox,area of a paper machine, where a magnetic field generator,for a constant magnetic field is provided in one of the two elements,that determine the gap and a measuring device for magnetic fields,is contained in the second of the two elements,determining the gap.
