The necks 10 of round bottomed plastic bottles 11 are fed into peripheral notches 9 of an upper turret plate 6, and stabilizing cups 47 are fed onto support plates 49 of vertically movable centering sockets 45 slidable in a lower turret plate 7 and disposed coaxially below the bottles. Pressurized gas in supplied to the bottles by vertically reciprocable stopper posts 23 to implement monitored seal testing, and while the bottles are stiffened by the gas the cups are adhesively applied from below. The various movements are synchronously controlled by rollers 33, 42 riding on circular cams 35, 44. |
