Title: APPARATUS FOR HEATING PREFORMS MADE OF THERMOPLASTIC MATERIAL
Abstract:
An apparatus (1) for heating preforms (10) made of thermoplastic material, comprising a conveyance device (2) for preforms (10) having a longitudinal axis of extension (100), intended to move the preforms along a predefined path (200), and heating means (3) arranged along at least one portion of the predefined path (200); the heating means (3) comprise at least one heating element (4) and at least one front reflective element (5), which are mutually opposite with respect to the predefined path (200) in order to form between them a transit tunnel for the preforms (10); the heating element (4) comprises a plurality of IR (Infra-Red) and/or NIR (Near-Infra- Red) lamps (4a); the front reflective element (5) comprises at least one contoured plate-like body in order to form, in the direction of extension of the predefined path (200), an alternation of closer portions (6a) and spaced portions (6b) with respect to the predefined path (200) that is extended substantially parallel to the axes of extension (100) of the preforms (10).
