DEVICE FOR WINDING FABRIC INTO ROLL Russian patent published in 2017 - IPC B65H77/00 B65H18/00 

FIELD: consumer goods industry.

SUBSTANCE: invention relates to consumer goods industry. Device for winding fabric into a roll has a pulsed sensor of the roll rotation, two comparators and an electric motor of the roll. Motor via a power amplifier is connected to the output of the first comparator. To the inverting input of the first comparator a tension sensor is connected, and to the direct input a tension setting unit is connected. Winding device additionally comprises the first and the second dividers, a roll radius sensor, a roll rpm counter, a reversing roll rpm counter and a unit for setting the number of turns of the fabric on the periphery of the roll. With the tension setting unit the output of the second comparator is connected. To the direct input of the second comparator the output of the first divider is connected, and to the inverting input the output of the second divider is connected. First inputs of the dividers are connected to the roll radius sensor. Second input of the first divider is connected via the roll rpm counter to the output of the pulse sensor of the roll rotation frequency. Rotation frequency sensor is connected to the first input of the reversing roll counter. Second input of the reversing rpm counter is connected to the output of the unit for setting the fabric number of turns on the periphery of the roll, and the output is connected to the second input of the second divider.

EFFECT: provided is higher accuracy of stabilization of the winding density.
