Steel Belt and Tracking 9: Air source of Edge Positioning Control

0.5MPa of air pressure is required in minimum, while during operation it uses only around 50 ml/min. On air supply we do give you advise. We recommend a handy compressor when you do not find air supply utility. Or employment of a booster or increase of bore diameter may be adequate when pressure is not prepared to the full extent.

Steel Belt and Tracking 8: EPC / Edge Positioning Control

Edge positioning is controlled by difference in pressure supplied to these 2 cylinders.
When the belt goes straight, supplied pressure is constant.
On the other hand when the belt leans to either right or left direction, air cylinder pressure on the leaned side is increased by control circuit, moving the belt to the opposite side.

Air cylinders are required to be heat-resistive, anticorrosive, and others, depending on operating conditions.
