Actuator system for use in control of a sheet or web forming process

A sheet forming system comprising:

• a quality control part comprising:
• one or more quality control systems for use in forming said sheet;
• a modulator/demodulator associated with at least one of said one or more quality control systems;
• an actuator driven part comprising:
• at least one actuator driven device having a plurality of actuators each associated with formation of said sheet, each of said actuators comprising a modulator/demodulator;
• a cable for providing an electric power signal from said quality control part to said actuator driven part, said cable connected to said modulator/demodulator associated with said at least one of said one or more quality control systems for modulating said electric power signal to carry communication signals from said quality control part for said actuator driven part;
• and
• each of said plurality of actuators further comprising means for receiving said modulated electric power signals from said quality control part without having said cable physically connected to each of said plurality of actuators, said modulator/demodulator associated with each of said plurality of actuators for demodulating said communications signals.

A sheet forming system comprising:

• a quality control part comprising:
• one or more quality control systems for use in forming said sheet;
• a power and communications module including a modulator/demodulator associated with at least one of said one or more quality control systems;
• an actuator driven part comprising:
• at least one actuator driven device having a plurality of actuators each associated with formation of said sheet, each of said actuators comprising a modulator/demodulator;
• and
• a cable for providing an electric power signal from said quality control part to said actuator driven part, said cable connected to said modulator/demodulator associated with said at least one of said one or more quality control systems for modulating said electric power signal to carry communication signals from said quality control part for said actuator driven part and to each of said actuator modulator/demodulators.

A sheet forming system comprising:

• one or more quality control systems for use in forming said sheet;
• at least one actuator driven device having a plurality of actuators each associated with formation of said sheet;
• a module for providing power to said plurality of actuators;
• a cable physically connecting said power providing module to each of said plurality of actuators;
• and
• a drive signal module connected to at least one of said one or more quality control systems for providing bi-directional wireless communications between said at least one quality control system and each of said plurality of actuators.
