Abstract
A lateral transfer preform loading method and apparatus for stretch blow molding machines. The method of the present invention incorporates the principle of laterally shuttling a set of finished products from a mold assembly and simultaneously shuttling laterally a set of preforms into the mold assembly. The first named set of finished products is discharged while the aforementioned preforms are going through a stretch blow molding operation to produce a second set of finished products. The second named set of finished products is then shuttled laterally from the mold assembly while simultaneously another set of preforms is moved laterally into operative relationship with the mold assembly. The aforementioned simultaneous steps of loading and unloading the mold assembly are continuously repeated. The mold assembly may be provided with one or more molds. The method may be carried out with a plurality of mold assemblies. The lateral transfer apparatus employed in the present invention includes, a loading station on each side of the mold assembly, and a pair of stretch pin assembly carrier means, whereby the pair of carrier means may be alternately and simultaneously moved laterally between their respective loading station and the mold assembly.
