Abstract
A method and an apparatus are provided for blow-molding hollow articles. The blow-molding apparatus includes a carrousel mounted to rotate within a support frame. The carrousel carries four molds around a circular mold path. Two blow-molding work stations are disposed next to the mold path in fixed positions relative to the frame. The carrousel is indexed to cause each mold to pause by each work station one time during each carrousel revolution. The molds pause by each work station to allow blow-molding operations to be performed in conjunction with each mold at each work station. At one blow-molding work station, located at the 12:00 position of the mold path, an extruder injects parison into each mold. At the other work station, located in the 9:00 position of the mold path, a take-out mechanism extracts blow molded articles from the molds. The carrousel is additionally indexed, i.e., 'double-indexed', to cause each mold to pause in the 10:30 position of the mold path where an in-mold labeling mechanism inserts a label into each mold.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
