Title
(EN) PREFORM COOLING APPARATUS
(FR) APPAREIL DE REFROIDISSEMENT DE PRÉFORMES
Abstract
(EN)
An apparatus (9) for cooling preforms (8), in particular preforms of bottles, made of thermoplastic material comprising - a plurality of supports (5) for the preforms (8) adapted to be moved along a path; wherein each support (5) is externally provided with a plurality of flaps (51); and wherein each support (5) comprises at least one cavity (52) adapted to accommodate a respective preform (8); the cooling apparatus (9) comprising at least one duct (11) adapted to receive an airflow generated by ventilation means (21) and configured to direct said airflow towards the supports (5) so that when the supports (5) and the preforms (8) inserted therein are at the duct (11), in particular placed side-by-side the duct (11) or below the duct (11), at least the supports (5) are hit by said airflow which exits from the duct (11).
