Abstract
A method and assembly for reshaping an elongated plasticized article including a pair of first and second spaced apart fixtures adapted to supporting extending ends of an elongated article. The fixtures each exhibit a contoured upper surface upon which the elongated article is adapted to being supported in adhering fashion. A heated airflow is delivered in communication with at least one surface of the article and, upon cooling, the article exhibits an extending profile matching the contoured upper surface. A pre-heat station pre-softens at least an extending subset portion of the article prior to transfer to the fixture. Pluralities of gripping fingers communicate with an underside of the contoured upper surface and are adapted to engage at least underside accessible cross sectional profile locations of the article.
