DEVICE FOR REGULATING TENSION OF WEB MATERIAL Russian patent published in 2014 - IPC B65H77/00 

FIELD: textiles, paper.

SUBSTANCE: invention relates to the field of textile production. The device for regulating tension of web material comprises a roll electric drive, a sensor of the roll speed of rotation, a tension sensor, a sensor of length of the wound material, an adder, a switching unit, a unit of setting the material module of elasticity, a unit of setting tension, a scaling unit, a second adder, a first and second units of division, and an integrator. The tension sensor is connected with its output to the first input of the first adder and the first input of the first unit of division. The second input of the first unit of division is connected to the output of the unit of setting the material module of elasticity, and the output to the first input of the second unit of division. The second input of the second unit of division is connected to the output of the sensor of length of the wound material. The output of the second unit of division through the break contact of the switching unit is connected to the first input of the second adder. The second input of the second adder through the open contact of the switching unit is connected to the sensor of length of the wound material. The input of the switching unit is connected to the sensor of the roll speed of rotation. The output of the second adder through the scaling unit is connected to the integrator input. The integrator is connected with its output to the input of the unit of setting tension. The output of the unit of setting tension is connected to the second input of the first adder. The first adder with its output is connected to the input of the roll electric drive.

EFFECT: improvement of accuracy of stabilization of winding density is provided.
