Abstract

A method for the contactless measuring of strand-like yarn material as well as to a device for carrying out the method. Textile material 4is irradiated within a measuring range of at least one ray source 1 and imaged on a sensor range of a receiving device 10 comprising sensor cells 8, 11, 12, 14. The signals generated by the individual sensor cells 8, 11, 12, 14 are converted into measured values for the dimensions of material to be measured 4. The signals of the sensor cells 12, 14 covered only partially by the image of the textile material 4 are taken into account in the measured result in a pro rata manner proportional to the amount of the covering.
