Abstract
Shuttle blow molding apparatus having an extruder or a blow head for substantially continuously emitting a thermoplastic material in tubular or parison form at a moldable temperature downwardly along a vertical axis. A finite length of the thermoplastic material is grasped by a first mold set, which then moves downwardly with respect to the extruder or blow head to provide clearance for a second mold set to move to a position to grasp a second finite length of the emitted thermoplastic. The first mold set is then moved horizontally away to permit the emitted thermoplastic length therein to be blown into a hollow article, and thereafter removed from the first mold set that is permitted to return and engage an other finite length of the thermoplastic material. The second mold set follows the first mold set in a path of travel traced by the first mold set. A single in-mold labelling device can be provided to sequentially apply labels to the interior of the mold sets, while the mold sets are open, for application to the articles being blown in the mold sets.
