Abstract
In continuous blow molding machinery employing a series of carriers successively traversing a closed path between preform loading, molding and molded article eject stations, an upwardly inclined removal ramp in the path of underblown parts but clear of the carriers is provided between the molding and loading stations for automatically removing such parts from the carriers. The method involves continuously stripping such parts before the loading station by elevating them relative to a rod portion of the carrier via interfering engagement with such ramp.
