OVEN FOR HEATING MOVING THERMOPLASTIC MATERIAL CONTAINER BLANKS

摘要

The invention concerns an oven (1) for heating moving thermoplastic blanks (preforms, intermediate containers), comprising conveying means (2) supporting and moving the blanks sequentially while rotating each of them about its own axis and heating means (3) arranged laterally to said conveying means (2) for heating the moving blank bodies; the conveying means (2) include at least two parallel conveying branches (4, 5), proximate each other and having opposite conveying directions, said two branches being travelled along one after the other by the blanks; the heating means (3) are arranged between said two conveying branches (4, 5) so as to heat simultaneously on both sides the blanks moving in opposite directions respectively on said two branches.
