FIELD: the invention refers to control of the state for example of textile materials at their interaction with working parts of technological equipment.
SUBSTANCE: the essence is in scanning the surface of the moving material with the aid of the sensitive element of a piezo-converter. The average value of the current linear sizes of the structural elements are calculated according to the number of the impulses generated by a piezo-converter and defined by the quantity of the elements of the structure (for example by the number of weave units) on the reference length of the part of the moving object. Periodically the received results are compared with the corresponding starting data of the structure of the rigid part of the material.
EFFECT: increases accuracy of the evaluation of the strain-deformed state of the moving easily deformed materials of a grid-type structure with simultaneous simplification of technical realization.
