Abstract

A continuous process for forming hollow, molecularly oriented articles which comprises: gravity-dropping molded preforms at molecular orientation temperature onto upwardly disposed moving stretch pin assemblies continuously presented at a loading station such that after loading, a closed end is above an open end of each preform, conveying the loaded assemblies into operative position between separated sections of continuous and synchronously moving molds, distending the preforms upwardly via stretch pin members and circumferentially via pressurized air after mold closing and while the preforms are at molecular orientation temperature in order to form the articles, opening the continuously moving molds, conveying the stretch pin assemblies with the upwardly disposed articles thereon away from the molds toward a removal station where the articles are removed from the assemblies without interrupting assembly movement generally back toward the loading station where the unloaded assemblies are again presented for receipt of additional preforms.
