Abstract

Method for measuring the degree of intermingling of yarns where an optical sensor is used to register intermingled and non-intermingled yarn sections, which comprises performing the measurement on a yarn which has been laid with no or low tension onto a moving support which transports the yarn past the optical sensor at a selectable, constant speed at a distance suitable for registering the yarn properties, and an apparatus for carrying out this method.
