ABSTRACT:
An air conveyor for plastic bottles conveys the bottles at generally constant speed. The bottles are of the type having annular rims around their necks and shoulders below the rims. The air conveyor includes a pair of spaced flanges and a plurality of nozzles for each flange. The flanges provide opposed inner edges which define a central slot extending elongately in the forward to rearward direction. Each flange supports a plurality of nozzles at spaced intervals in the forward to rearward direction for substantially the length of the slot. An air blower supplies pressurized air to the nozzles. Each nozzle discharges air in a stream along a diagonal direction that generally slopes downwardly, inwardly, and forwardly. In use, the flanges provide the neck rims with slidable support as the bottles are blown forwardly through the slot by the force of the air streams against the shoulders. Constant speed is gained through the direction of the air streams against bottle shoulders.
