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.
Claims15
A method for thermally conditioning preforms (14) before they are formed by stretch blow-molding, in a facility (100) for producing containers (12), the method comprising:
- at least a first step (E1) of heating each preform (14) by transport along a heating path (66) exposed to heat radiation, the preforms (14) exiting the heating path (66) at a predetermined production rate (R);
- a second step (E2) of diffusing the heat stored in each preform during which the preforms (14) are transported in a line along a diffusion path (70) that is not exposed to the heat radiation and extends from a downstream end of the heating path (66) to a station (52) for forming the preforms (14);
- and
- a third step (E3) of transferring the preforms, following the diffusion step (E2), into forming units (56) of the forming station (52) at said predetermined production rate (R),
- wherein the diffusion path (70) comprises at least one final buffer section (70A) that the preforms (14) travel along in an adjustable duration (Da).
