  • Unrolling Device for a Material Web
    Publication number: 20110088619
    Abstract: A towel dispenser which sprays portions of a material web pulled off from a supply roll with a disinfectant. A disinfectant supply bottle is arranged partially inside a core of the supply roll, and its liquid outlet is connected to the inlet of a diaphragm pump, which feeds into a nozzle pipe. To measure the residual material web remaining on the supply roll, an angular velocity transmitter is used which comprises a stationary reflective light barrier and a line pattern applied to the inside of the core of the supply roller.
