CONTROL DEVICE FOR FORMATION WARPING SHAFTS Russian patent published in 2012 - IPC D02H13/18 

FIELD: textiles, paper.

SUBSTANCE: control device for formation warping shafts includes electric motor of a warping shaft, an electric motor of a pressure beam connected to the transducer, an actual radius measuring device, a calculator of the theoretical radius of the warping shaft, a pressure sensor of the pressure beam, pressure setting unit, a relay unit, and two summation units, at that the outputs of the calculator of the theoretical radius and the outputs of the actual radius measuring device are connected to the inputs of the first summation unit, whose output is connected to the input of the pressure setting unit, which is connected with its output to one of inputs of the second summation unit, which second input is connected to the output of the pressure setting unit, and an output - with the input of the relay unit, connected with its output to the input of the transducer.

EFFECT: improved accuracy to maintain the parameters of winding of the warping shaft.
