Abstract
A method and a device for winding metal strip onto a mandrel to which the metal strip is fed by a driver encompassing a bottom and a top drive roller in a driver frame. In order to regulate the driver in such a way by measuring the strip tension, the longitudinal tensile strength applied to the metal strip by the driver to control the strip run through the driver is determined by means of a strip tension measuring device which is mounted on the driver frame, in a pivot located shortly behind the bottom drive roller, and can be swiveled into the metal strip from below. The strip tension measuring device is composed of a first lever arm and a second lever arm which is hingedly mounted at the front of the first lever arm and the forward end of which is provided with a roller.
