DEVICE TO CONTROL FORMATION OF WARPING ROLLS Russian patent published in 2011 - IPC D02H13/28 

FIELD: textile, paper.

SUBSTANCE: device to control formation of warping rolls comprises electric motors of a warping and a rolling rolls, connected to converters that feed them, a metre of actual radius of a warping roll and a calculator of its theoretical radius, a unit of current setting and a sensor of a warping roll motor current, a two-position relay, the first and second summators, besides, outlets of the metre and the calculator of radii via the first summator are connected to the inlet of the current setting unit, outlets of the current setting unit and the current sensor via the second summator are connected to the two-position relay, outlet of which is connected to the inlet of the rolling roll motor converter.

EFFECT: increased accuracy of formed parameters of a warping roll winding, main of which are density and length of a wound warp.
