Embodiment Construction

[0080] In the following description and claims, the non-limiting use of "longitudinal", "vertical" and "transverse" orientations is used according to the definitions given in the description and relative to the illustrations shown The three-sided reference system (L, V, T) indicates the components separately.

[0081] Conventionally, the terms "upper" and "lower" will be used to define the vertical orientation of the element relative to the three-sided reference system (L, V, T), which does not refer to the gravity field of the earth.

[0082] Similarly, the terms "upstream" and "downstream" will be used with reference to the direction in which the preform travels along the heating path, or alternatively, to the direction in which the cooling air flows through the furnace.

[0083] The same, similar or similar elements of the present invention are represented by the same numeral signs.

[0084] figure 1 An embodiment of the furnace 10 for heat-treating the thermoplastic preform 12 is ...

Abstract

An oven (10) for the heat treatment of preforms and a method for operating an air-cooling device (42) fitted to such an oven includes controlling elements (58) to vary the cooling air flow rate onto the body (18) and bottom (20) of the preforms (12) along the heating path.

Description

Technical field [0001] The present invention relates to a furnace for heat treatment of preforms and a method for operating an air cooling device installed to the furnace. [0002] The present invention more particularly relates to an oven for the heat treatment of thermoplastic preforms, each preform correspondingly comprising a first part and a second part, the first part being in its final shape, and the second part It is used for heating by a heating component, the heating component is arranged along at least part of the determined heating path, the preform follows the heating path and passes through the furnace, the furnace includes a cooling system, the cooling system The first part and the second part of the preform can be cooled. Background technique [0003] Generally, the present invention relates to the field of container manufacturing. The container is obtained by transformation of preforms, particularly by blow molding or stretch blow molding, and preforms are obtaine...
