Abstract: A process and apparatus to reclaim solid polystyrene-type polymer material in solid form comprising a dissolving section to dissolve the solid polystyrene-type polymer material in a solvent including a dissolving tank to receive solvent from a solvent reservoir and the polystyrene-type polymer material from an external source to form a solution thereof and a recovery section including a recovery tank to receive the solution from the dissolving section, a separator unit to separate the dissolved polystyrene-type polymer material in solid form from the solvent, a solid material processing unit to remove the reclaimed polystyrene-type polymer material from the separator unit and a fluid separator/recovery unit to remove moisture from the separator unit and separate and recover the solvent from the water.

Abstract: A blow moulding method. Cold parisons are conveyed through an oven for heating and then stretched and blown in a mould. A transfer assembly, engages the upper end of each heated parison, removes it from the oven, and swings it into a mould and then rises to stretch the parison as a threading die holds the lower end thereof. The mould then closes and air is injected to form the bottle, after which the mould opens and the finished bottle is removed.

Abstract: A blow molding apparatus including a rotary frame located adjacent a parison heating oven and having a plurality of blow molds mounted thereon for rotation therewith about the frame axis. A separate transfer arm is provided for each blow mold, the transfer arms also being located on the rotating frame for rotation therewith, each transfer arm being operable to transfer heated parisons from the oven to its respective blow mold.
