ABSTRACT:
An apparatus for engaging and feeding containers to a printing press, including a support frame having a plurality of shafts mounted thereon; a plurality of worm members mounted on the shafts and each having spiral grooves for engaging a bead of a container, the worm members being movable between a first position for engaging the bead of a container and a second position disengaged from the bead of the container. In addition, the container feeding apparatus includes a feeder tube mounted on the support frame for setting and controlling the location of the first position of the worm members and for supplying the containers to the worm members. There are also a plurality of worm block assemblies mounted within the support frame each including drive means for rotating one of the plurality of worm members while in the first position to simultaneously engage the bead of the container to move the container forward relative to the feeder tube to the end of the spiral grooves. The container feeding apparatus further includes a pneumatic air assembly for injecting air at the container for transferring the container from the end of the spiral grooves to a mandrel for receiving the container for printing; and a cylinder pivot assembly for moving the worm block assemblies between the first and second positions.
