Abstract
A parison tube former utilizes a radial compression heater to heat a very specific portion of a preform tube for stretching. The heater has a plurality of compression dies that form a central cavity for receiving the preform tube. The working surfaces of the compression dies close down onto the outer surface of the preform tube to heat the tube via conduction, which more accurately and precisely heats the preform tube. A first stretched portion of the preform tube is produced by stretching the preform tube after heating. A second portion of the preform tube is then located within the central cavity and is also heated by the radial compression heater and stretched to produce a second stretched portion of the preform tube and an unexpanded portion of the preform tube, or balloon portion of the parison tube.
