FIELD: textiles, paper.
SUBSTANCE: to control the characteristics of the thread in the working process the sensors of determining the stock, shortage and the thread tension are used, as well as the sensors of rotation, lowermost and uppermost positions of the main shaft of the sewing machine, and the size of the presser foot raise. The data obtained from the sensors are processed in the controlling system, and the characteristic of using the thread is formed as the algebraic sum of the values of the thread stock and its lack (has the negative value), taking into account the value of the thread deformation, which is set by the values of the thread stock and the thread tension, as well as taking into account the parameters of stitches, the type of the thread and the processed material. Registering the characteristics of the thread usage occurs in all phases of stitch formation.
EFFECT: method has the ability to customise for different types of material and the thread used.
