Estimating the term…
This relates to a blow molding system wherein a plurality of preforms are simultaneously blow molded within a mold set with the preforms being carried by one or more carriers which move first to a loading station to receive preforms, then through an oven to heat the preforms, then into a mold set wherein the plural preforms are simultaneously blow molded, then to an ejection station where the blow molded articles are discharged, and finally back to the loading station. There are two mold sets which are part of a clamp which operates sequentially to open and close each mold set with one mold set being closed as the other mold set is being opened. The carriers may travel either in a single continuous path for sequentially positioning at first one mold set and then the other, or there may be two continuous circuits for the carriers in which event the two mold sets of the clamp may be different. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
A blow molding clamp assembly comprising fixed remote mold half sets, companion mold half sets mounted as a unit and for movement for selected cooperation with a respective one of said fixed mold half sets wherein when one set of said mold halves is closed the other set of said mold halves is open, said clamp assembly including a track section associated with each set of mold halves for receiving preform carriers, means mounting each of said track sections for movement between a position generally centered relative to a respective set of mold halves when open and a position centered relative to said respective sets of mold halves in their closed positions, and the positions of said track sections when aligned with open mold halves being different.
