Abstract
Abstract An electronic damping element is interposed between the forcemeasuring instrument and indicating instrument to produce a mean value from the signal emitted from the measuring instrument for recording as a smooth deviating line by the indicating instrument. The damping element can be switched on or off. The mean value can be preset by regulating the speed ratio between the roller assemblies.

Claim 1
Independent Claim
114 words
A process for determining the strength and elongation of a thread running continuously between an input drive means and an output drive means comprising the steps of elongating the thread between the drive means to generate a tension therein, transforming the generated tension into an electrical signal, recording the value of said signal on a paper chart, selectively damping said signal to produce a mean value of thread tension signal, adjusting the elongation of the thread to a predetermined mean value of thread tension, and reading tee degree of elongation responsive to the mean value of thread tension to determine the ratio of speed between the input drive means and the output drive means.
