Title:
DETECTION OF A PERIODIC STRUCTURE IN A MOVING ELONGATED TEXTILE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2014/089714
Kind Code:
A3
Abstract:
In a method for detecting a periodic structure in a moving elongated textile material (9), said textile material (9) (e.g. yarn) is sampled simultaneously at multiple detection points (43.1-43.5) located equidistantly in the longitudinal direction (91) of said material. Sampling signals that can be detected at the detection points (43.1-43.5) are added to form a composite signal (for example by means of an integrated optical waveguide structure.) Temporal changes in the composite signal are indicative of a periodic structure in the textile material (9). A localised spectrum of the structure of the textile material (9) can be obtained (Fourier spectrum) with multiple groups of multiple equidistant detection points (43.1-43.5) with practically no computational effort.
