Line & edge follow controller
It is the detector adjusting the edge of the web in line as loght emitting sensor. In case of opaque materials, light emitting part is consist of L.E.D.and receiving units is consist of C.D.S.as so that is semi-permanent and excellent detecting.
Powder brake
When no current flow in the magnetic coil, powder is being attached to in put drum side by centrifugal force as separate in put drum and out put drum. So the torque is not transmitted. If coil is exited by electric current, magnetic flux is generated, then torque is transmitted by the friction between powder and working side.
This equipment is to detect the tension of web as pick up detector which installed at the both end roller.
Also it is to controlled the "excitation current" of the powder brake & clutch as automatic in order to make tension difference "zero" between detected tension and set-up tension.It is high mechanical response time of the detection part and super precision tension control.
Proximity Tension Controller is control the tension of web material by the proximity sensor fixing at web material roller for perceptive accuracy web roll diameter in order to make the tension difference "zero" between the result & object and control "excitation current" feeding back from the powder clutch & brake.
Available high mechanical response time of the detection part and super-precision tension control.
