DEVICE TO CONTROL FORMATION OF WARPING ROLLS Russian patent published in 2017 - IPC D02H3/00 D02H13/00 

FIELD: textile, paper.

SUBSTANCE: device to control the formation of warping rolls contains a warping roll electric drive, a compressing roll electric drive, a winding radius calculating unit, a warping roll speed sensor, a compressing roll rotation impulse speed sensor, a warping roll impulse speed sensor, a winding radius increment determination unit. Warping roll impulse speed sensor and compressing roll impulse speed sensor are connected with their outputs to inputs of winding radius calculating unit, an output of which is connected to the first input of the winding radius increment determination unit of the warping roll, the second input of which is connected to the output of the warping roll speed sensor, and the output of the winding radius increment determination unit is connected to the compressing roll electric drive, according to the invention, comprises a compressing roll rotation electric drive, a contactless winding radius sensor and an adder. Output of winding radius calculating unit is connected to the first adder input, the contactless winding radius sensor is connected to its second input, and the adder output is connected to the compressing roll rotation electric drive.

EFFECT: improved stabilization accuracy of bulk winding density.
