ABSTRACT:
A method and apparatus for continuously measuring the variability of an advancing textile strand is disclosed, and wherein the output signal is useful in diagnosing the source of the variations. The method includes the steps of continuously monitoring at least one selected parameter and applying the resulting signal to each of a plurality of integrating networks each having a different predetermined time constant. The output signal from each of the integrating networks is then applied to a root mean square network to produce an output which closely approximates the standard deviation of the output signal of the associated integrating network. In a further embodiment, the signal from the monitoring device is applied to an integrating network, and the output of the integrating network is applied serially to two root mean square networks. Several embodiments of a transducer are also disclosed which are designed to permit the monitoring of a number of parameters in the moving textile strand.
