Abstract: Provided is a thermal conditioning method of preforms. The method includes heating each preform by transport along a heating path exposed to heating radiation with a determined production rate; transporting the preforms (in line along a diffusion path; transforming the preforms in forming units at the determined production rate. The diffusion path includes a final buffer section along which the preforms travel for an adjustable duration.

Abstract: A device for ejecting products in a unit for processing products, a flow of the products moving one behind the other along a circulation trajectory. The device having an ejector for individually ejecting a product out of the circulation trajectory and a motor of the ejector. The ejector having at least one plate with a peripheral edge provided with at least one recess for receiving a single product and the motor having a rotation drive for the plate and a way for synchronizing the drive with the flow of the products. The invention relates also to an installation and an ejection method.
