Abstract
Apparatus for the continuous measurement of the elastic coefficient of a traveling strip, wire or ribbon, is characterized in that it employs first and second means for driving the strip arranged one behind the other in the direction of motion of the strip. The second driving means drives the strip at a speed different from that of the first driving means and first and second tension measuring devices are disposed in front of the first and second driving means, respectively, and deliver respective quantities which are proportional to the tensions measured thereby. A comparator circuit is provided for determining the difference in the measured tensions, this difference being proportional to the elastic coefficient of the strip.
