摘要 |
To determine its diameter or cross-section, a thread 11 is caused to travel between a light source 10 and a receiving device 13. The illumination of the device 13 is measured by the shadow (as shown) or reflection of the thread 11. The device 13 has a series of individual photo sensors which are scanned to produce a representation of the diameter or cross-sectional image in the form of a pulse sequence, avoiding the need for an analog digital converter. For non-circular cross- sections a two-beam system is used (Fig. 4 not shown). By use of suitable pulse thresholds the roughness of the surface is measured. Also the thread position or the presence of protruding bristles may be detected. <IMAGE> |
