Abstract

A system for measuring the weft or mesh serial position in textiles, in which the angular position of the weft/mesh series is measured for determining the angle of distortion passing over a partial amount of the length thereof, includes an illumination measuring system which measures values of light from a light source either passing through or reflected from the textile fabric to be tested, in a substantially linear range, and an adjusting assembly which reciprocally and oscillatingly rotates the linear range about a central angle to adjust the linear range at an angle relative to the textile fabric; rotating or measuring the reflection or transmission values in several discrete equidistant angular units; a group of memories for storing the measured values corresponding to at least a few angular units; and a digital unit connected to the memories for comparing the stored values in calculating a distortion angle in response to such comparison.
