The tension control system can detect the braking torque by the brake itself, so the sensing roll isn`t necessary. Therefore, it is the best for the tension control of papermaking multilayer cutter.
The tension control system can accurately control the tension of the each unreel.
It is a method of automatic batch control that the torque signal and rotation signal etc. of the each unreel stand are directly transferred to the main computer. The pressure reducing valve, pressure gauge, and the manual local operation box which only has the mechanical valve for switching run or stop, will be placed in each unreeling stand.
Functions of Japanese and American Patent
|It`s possible to control the tension of the multilayer cutter at the each unreeling stand.||The tension control for each winding has become possible which almost has been regarded as impossible at the conventional multilayer cutter.|
|Apply to all kinds of brake types||Apply to any brake types such as a floating type, a friction type, a motor type, an electromagnetic type, and a powder brake type.|
