A winding apparatus providing steady tension includes: a loading unit rotatably supporting a roll of a sheet, releasing the sheet, and outputting an angle signal and a torque signal; a winding unit adapted to collect the sheet into a roll form; a dancer roller and a tension sensing unit separately arranged between the loading unit and the winding unit and outputting a shift signal and a tension signal respectively; and a control module having a calculating unit and a command unit. The calculating unit electrically connects with the loading unit, the dancer roller and the tension sensing unit to receive the signals and generates a torque command signal. The command unit electrically connects with the calculating unit and the loading unit to receive the torque command signal and produces a control signal by the torque command signal or a velocity signal. |
