FIELD: textiles, paper.SUBSTANCE: device of control of formation of warping shafts comprises an electric drive of the warping shaft, an electric drive of the compacting shaft, a speed sensor of the warping shaft. The device additionally comprises a measuring instrument of the length of wound base, a calculator of rotation angle of the warping shaft, the initialisation unit of winding radius, a setting unit of the density index of winding, a squaring device, a multiplier unit, a division unit, and two adders. At that the speed sensor of the warping shaft is connected with its output through the calculator of rotation angle of the warping shaft to the first input of the multiplier unit and to the input of the squaring device which is connected with its output to the first input of the division unit which is connected by its second input to the output of the first adder which first input is connected to the output of the multiplier unit and the second - to the output of the sensor of the length of wound base. At that the output of the division unit is connected to the first input of the second adder, which second input is connected to the output of the setting unit of the density index of winding and the output is connected to the input of the electric drive of the compacting shaft.EFFECT: increased accuracy of stabilisation of winding density and length of the wound base.1 cl, 1 dwg |
