ABSTRACT:
A laminated stack has grooves on the faces of the laminations forming fluid amplifiers and control channels therefor. Pneumatic detectors are coupled with the control channels. The laminations are perpendicular to the path of travel of workpieces to be treated, such as glass sheets, and outlet nozzles of the fluid amplifiers and openings of the pneumatic detectors face the glass sheet. Preferably opposed stacks on each side of the path of travel each emit detector jets to jet receivers of the other stack, and the nozzles thereof simultaneously treat both sides of the workpiece. The laminations may be oblique to the path of travel. Upstream and downstream detectors and combinations thereof are disclosed, including an Exclusive OR arrangement.
