Abstract
Provided is a thermal treatment unit for preforms that includes an element for blocking radiation toward the neck of the preforms. The unit can include a first wall having a first heating element and a second wall having a second heating element, a first grip and move system for gripping and moving preforms on a first row, a second grip and move system for gripping and moving preforms on a second row. The unit also includes a blocking element extending between the first and second rows to block radiation emitted by the first heating element and the second heating element toward the second grip and move system and toward the first grip and move system, respectively.
Claims10
A thermal treatment unit for preforms of a container manufacturing installation, the thermal treatment unit comprising:
- a chamber delimited by a first wall and a second wall extending on either side of the chamber in a transverse direction, the first wall comprising at least one first heating element and the second wall comprising at least one second heating element,
- a first grip and move system for gripping and moving a first plurality of preforms on a first row (R1) adjacent to the first wall, said first grip and move system being designed to interact with a neck of each preform of the first plurality of preforms so as to move said preforms along a predefined circulation path (T) extending in a longitudinal direction substantially perpendicular to the transverse direction,
- a second grip and move system for gripping and moving a second plurality of preforms on a second row (R2) adjacent to the second wall, said second grip and move system being designed to interact with a neck of each preform of the second plurality of preforms so as to move said preforms along the circulation path (T),
- wherein the thermal treatment unit comprises at least one blocking element extending between the first row (R1) and the second row (R2) so as to block radiation emitted by the first heating element toward the second grip and move system and to block radiation emitted by the second heating element toward the first grip and move system such that the necks of the preforms of the first row (R1) and of the second row (R2) are not heated by the first and second heating elements.
