ABSTRACT:
A module for heating a plastic container perform, includes a longitudinal heating tunnel bounded transversely by the longitudinal vertical internal faces of two walls, one a heating wall, being equipped with a heating system, and the other wall having aeration orifices that are intended to let the air blown by a blower pass through them transversely from the upstream, and in which module a first portion of the preform is heated in the heating tunnel, while a second portion of the preform is held outside the heating tunnel through a longitudinal opening. The blower includes a deflector that deflects a portion of the air blown towards the second portion of the preform so as to prevent it from being heated up to its softening point, characterized in that the upstream end of the deflector is aerodynamically profiled.
