Abstract (en)
When winding a material web on a winding roller (8) the extension of the web is determined by measuring the change in length of the web between two measuring points (11,15) with different tension. The material web can be provided with colored markings whose spacing is determined. The dye can become invisible after a final time of less than 15 minutes.
