DEVICE FOR ADJUSTMENT OF TENSION OF MATERIAL AT WIDEVICE FOR ADJUSTMENT OF TENSION OF MATERIAL AT WINDING NDING

摘要

A device for adjustment of tension of a material at winding contains a winder, an electric drive of the winder, a sensor of the linear speed of the material, a setting device of tension. The setting device of tension is made in the form of a programmer, which contains the unit of formation of predetermined program of tension, calculating unit of current radius of roll, unit of determining the useful torque of electric motor, unit of determining the moment of losses in electric motor and winder, unit of determining the dynamic moment of electric drive, unit of determining the moment of aerodynamic strength of materials, unit of determining the moment of the deformation of material at bending on the roll, unit of determining the prescribed moment of electric motor, unit of determining the signal of setting of electric drive, unit of calculating the current radius of roll, units of determining the net torque of electric motor, unit of determining the moment of losses in electric motor and winder, unit of determining the moment of aerodynamic strength of materials.
