APPARATUS FOR PRE-HEATING THERMOPLASTIC PARISONS |
摘要 |
<p>TITLE APPARATUS FOR PRE-HEATING THERMOPLASTIC PARISONS This invention relates to an apparatus for effecting the uniform pre-heating of thermoplastic parisons of the type that are introduced into a blow molding machine for fabrication into a blow molded article. The invention provides a hopper which is intermittently supplied with batches of parisons and through which the parisons move by gravity. A convection heating zone is provided in the hopper to uniformly heat each parison passing therethrough, and a temperature equalization zone is provided adjacent to the heating zone. The parisons are removed from the temperature equalization zone by a continuously moving parison conveyor which forms part of the temperature equalization zone.</p> |
