<p>A conveyor chain moves along the periphery of a table. A number of balloon-carrying members are fixed in spaced-apart relationship to the conveyor chain. Each member carries a nipple for engaging the neck of a balloon and a balloon-positioning member movable with respect to the ballooncarrying member between a retracted position and an extended operative position surrounding the neck of the inflated balloon and maintaining the inflated balloon in steady position to be printed by a silk-screen printing press. The ballooncarrying members move in a close path,step by step, through successive stations as follows: stations where deflated balloons can be attached to a nipple; stations where the balloons are inflated; a station where the balloonpositioning member is pushed outwardly to its operative position; a station where the balloon is printed by a silk-screen press; several stations where the ink on the balloon is dried; a station where the positioning member is retracted; and a final station where the inflated balloon is detached from the nipple.</p> |
