Abstract: A machine for leak testing melt blown bottles includes a base plate and is provided with a vacuum. The machine includes a turntable assembly, which has an inner ring fastened to the base plate. The inner ring includes a channel about its circumference connected to the vacuum. An outer ring is formed of multiple parts, and fitted slidingly but sealingly around the inner ring. The outer ring has vacuum ports in communication with the channel of the inner ring. A turntable is rotatably connected to the outer ring and includes openings formed in its upper surface communicating with the vacuum ports. The outer ring may be held together by one or more O-rings. Vacuum fittings transfer the vacuum between the openings in the turntable and the vacuum ports of the outer ring.
