ABSTRACT:
An article repositioning apparatus for an injection stretch blow molding machine is disclosed for simultaneously molding a plurality of containers from plastic parisons. Between work stations, the apparatus repositions articles from a compact, evenly spaced first position to an extended, unevenly paired second position. After insertion of the articles into receivers slidably mounted on tracks, the receivers are moved by a servo motor to various separations by sliding movement along the tracks, the receivers attached to aligning ribs threadably engaged with ball screws. Simultaneously, the tracks are moved by a second servo motor to uneven paired separations by attachment to movable scissors having large and small scissor portions.
