Measurement Of Velocity With Cross-Correlation Technique For An Industrial Application

* Istituto Nazionale di Ottica, Largo Enrico Fermi 6 - 50125 Firenze, Italy* *Cerimates, via Villanova di Sotto, 33170 Pordenone, ItalyAbstractIn the process of continuous spinning it is particulary important the measurement of thevelocity of textile fibers: in fact the uniformity, smoothness and tenacity of the yarndepend on the velocity of the fibers at the moment they reach the twisting organ and on theaverage number of the collected fibers. It is important that the applied tecnique shouldnot affect the flow. An electro- optical system is described for the measurement of thevelocity of fibers
