ABSTRACT OF THE DISCLOSURE A device for measuring the winding hardness of a strip, especially a strip of paper, that has been wound into a reel. The device consists of a mechanism for extracting a slip that has been inserted tight between two coils of the reel of paper with one end extending out of the side of the reel and of a dynamometer that measures the force necessary to extract the slip over a certain distance. To allow winding hardness to be displayed directly rather than in the form of a graph, the slip-extracting mechanism operates at a constant extracting speed, a pulse generator that is supplied with the resulting force, or with a control signal derived from it, by the dynamometer supplies counting pulses to an up-down counter at a frequency that is proportional to the force, and the slip-extracting mechanism is connected to an odometer that, when it detects equal distances, switches the counter from up to down and stops it.
