ABSTRACT:
A gas operated balloon inflating machine for inflating balloons of the kind having a body and a filling neck terminated in a beaded edge. The apparatus includes a gas operated releasable clamping device to secure the beaded edge of the balloon between a support surface and a sealing surface thereby providing for inflation of the balloon from an aperture in the sealing surface. A gas operated control valve selectively supplies gas to the aperture from a reservior and a gas operated sealing device is used to seal the neck of the balloons after inflation. A logic controller selectively supplies pressurized gas from a high pressure source to the clamping device, control valve and sealing means to sequentially clamp, inflate, seal and release balloons. The exhaust gas from each of these devices is directed to the reservoir for inflation of the balloons. The size to which the balloons are inflated is preferably controlled by the size of the inflating reservoir and regulation of the pressure in the reservoir.
