  • Patent number: 4025261
    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.

  • Patent number: 3945682
    Abstract: In transfer apparatus for receiving lightweight articles such as containers made of plastic material, from a chute, and delivering them to a conveying means, the combination is provided of a turntable or dial having partition members forming circularly disposed receiving pockets rotatable in a generally horizontal plane below and successively in registry with the chute discharge opening, such pockets arranged for removal of the articles by the conveying means in a horizontal direction on reaching a discharge area on an arcuate path of travel thereof. Pocket loading means synchronized with movement of the dial are preferably used. The method involves successively feeding the articles individually at regular intervals to the rotating pockets, advancing the articles in the pockets along an arcuate path to a discharge area and continuously moving each article out of such discharge area in a direction generally tangential to the arcuate path.
