摘要：
Method and apparatus for monitoring a winding hardness of a winding roll when winding a material web. A series of marks are placed on the material web at a first location as it is wound onto the winding roll. The distance between two successive marks is detected at a second location. The detected distance of two successive marks is used to determine a stretch of the material web.
