[ /av_heading]The web aligner system is much more than just a power source. It’s designed for accurate and high quality edge guidance system. However, because it normally supplies modulated power to impulse devices. It is the amplifier of control signals, also a source of energy in addition to the supply of hydraulic power for the impulse circuit the powertrain produces the pneumatic power for the sensors. The high quality pressure from the sensor source must remain constant, and the power supply supplies this element. Water, oil and scale contamination and other miscellaneous plant air problems are also avoided.
