METHOD AND DEVICE FOR ASSESSING THE SURFACE CONDITION OF RUBBER OR PLASTIC STRANDS

摘要

A device for assessing technical condition of the surface of strands made of rubber or plastic comprising temperature generator, temperature detector, interface, image analyzer, and decision element is characterized in that it has an infrared detector (3) located over the examined structure of strand (1) at appropriate distance (h) and in an antireflection shield (4), whereas uniformity of the temperature gradient over the whole surface of the examined structure of strand (1) is ensured by a temperature generator (2) after which temperature sensors (6 and 7) are located. A method of assessing technical condition of strands made of rubber or plastic is characterized in that that signals from sensors (6, 7) measuring the temperature gradient and the signal from the transducer (5) providing non-contact and/or contact measurement of velocity of strand (1) and the image from interface of detector (8) are transmitted to image analyzer (9) and decision element (10).
