In a method and apparatus for continuously measuring the annealing level on wires or strips, a wire or strip is passed, in a continuous feed, over a pulley of small diameter, at a tension less than that corresponding to the elastic limit of the material of which the wire or strip is made, so as to produce permanent elongation of 0.1 to 1%, this elongation being taken as a measurement of the annealing level, and utilized to control the annealing level.
