Non-Round container blow molding apparatus |
摘要 |
Method and apparatus for forming stretch blow molded containers having uniform sidewall thickness from physical symmetric parisons. Parisons are heated non-uniformly by rotating at a non-uniform rate in a heating station. A sensor determines the angular orientation of the parisons emerging from the heating station. Each parison is angularly reoriented at a repositioning station prior to introduction into a stretch blow molding station having non-round interior surfaces, so that the temperature profile of each parison corresponds with differential expansion required to form the desired non-round container.
