Beschreibung
Zusammenfassung:	Method for detecting irregularities in the gauge of a flexible material that can be found over the width of the material and along its length. The material is wound around a winder and while being wound is illuminated using a light bundle that reflects light back so that its reflection point can be spatially resolved and used to detect variations in the winding surface shape. Changes in the winding surface shape are caused by irregularities in the gauge of the wound flexible material. The invention also relates to a device for detecting changes in dimension or gauge of a wound flexible material.
