ABSTRACT:
Post mold cooling apparatus and method having transverse movement preferably includes structure and/or steps for cooling a plurality of plastic articles molded on a row of mold cores. A post mold cooling device is provided having (i) a first row of cooling tubes configured to hold a first plurality of the molded plastic articles, and (ii) a second row of cooling tubes configured to hold a second plurality of the molded plastic articles. A cooling station is disposed adjacent the cooling device and is configured to provide a cooling fluid to an interior of both the first and second pluralities of molded articles inside the respective first and second rows of cooling tubes. Movement structure is configured to (i) provide a rotational movement to cause the first and second pluralities of molded articles inside the respective first and second rows of cooling tubes to be presented to the cooling station, and (ii) provide a transverse, axial movement to alternately cause the first row of cooling tubes and then the second row of cooling tubes to be presented to the row of mold cores.
