Method and apparatus for trimming the neck of plastic bottles includes means for rapidly rotating a cutting blade around the neck being trimmed while progressively moving the cutting blade through the thickness of the neck. During the cutting, a flat surface of the cutting blade rubs against the newly cut upper neck or finish surface to provide a polished surface therefor.

Chipless trimming of plastic bottles

A hot fill apparatus for use in the testing of hollow thermoplastic containers, the apparatus having a reverse osmosis filter system, a heater system and a fill head system. The reverse osmosis filter system removes chlorine and other particulates and contaminants from the water prior to the water entering the heater system. The heater system is designed to maintain strict temperature control of the water while maintaining a steady flow rate and pressure. The fill head system includes a manually operated spigot and an automatically operated fill head, the operations of which are mutually exclusive.

Hot fill apparatus and process therefor

A process for crystallizing a thermoplastic preform or container which utilizes a preheated plug to provide the sole upright support for a workpiece in the crystallizing process. The preheated plug aids in the crystallization process by applying heat to the interior surface of the finish area while heat is also applied to the exterior surface of the finish area to crystallize the finish area. The thermoplastic preform or container is then cooled and removed from the plug.

Crystallizing process

A machine for crystallizing a thermoplastic preform or container is constructed from modular subassemblies and utilizes a preheated plug to provide the sole upright support for a workpiece in the crystallizing process. The first modular subassembly includes the workpiece in-feed and plug preheat structures and incorporates the drive apparatus for the entire machine. The opposed end of the crystallizing machine is constructed of a subassembly which operates to provide the turnaround and tensioning takeup for the carrier mechanism transporting the workpieces. Positioned between the first subassembly and the opposed end subassembly are heating and cooling processing modules which can be provided in any number depending on the size constraints and workpiece quantity restraints desired. The processing modules provide the heating and crystallizing processes for the desired area of the workpiece and the cooling process of the workpiece prior to unloading.
