Problems solved by technology

[0007] The unique inherent characteristics of the currently known laser sources are not enough to ensure good uniformity and high productivity of the heating of the blank. For this reason, the research on the structure of the heating unit is still indispensable.

Embodiment Construction

[0034] A processing unit 1 for container blanks 2 traveling in a file is schematically shown in these figures. The blank 2 is in this case a preform, but it may relate to an intermediate container which has been subjected to a temporary forming operation and intended to undergo one or more final operations to obtain a finished container. Likewise, the treatment is in this case a thermal treatment by infrared radiation but it may involve a decontamination treatment by ultraviolet radiation.

[0035] The preform 2 is shown neck-up, but it could also be shown neck-down.

[0036] As can be seen in the figures, the treatment unit 1 comprises two opposite walls, namely a first wall 3 and a second wall 4 facing said first wall, the first and second walls together define An enclosure 5 within which the preform 2 travels along a predetermined path T defining a longitudinal direction. This path T is linear in the illustrated embodiment, but it may be (at least partially) curved depend...

Abstract

A processing unit (1) for processing rough blanks (2) having a hollow body made of plastic material, said processing unit comprising an enclosure (5) equipped with two opposing walls (3, 4), Namely a first wall (3) and a second wall (4) opposite to said first wall, the first wall and the second wall together define an enclosure (5) in which the blank (2) The inside travels along a predetermined longitudinal path, wherein: each wall (3, 4) includes a series of spaced radiators (7), each radiator includes a plurality of single-frequency or pseudo-single-frequency electromagnetic radiation sources; The section (15) extends in each space between two adjacent radial bodies (7); the radial body (7) of the second wall (4) is opposite to the radial body (7) of the first wall (3). ) are longitudinally staggered such that the emitter of each wall (3, 4) faces the reflective section of the opposite wall.

Description

technical field [0001] The invention relates to the process for the manufacture of hollow bodies, such as containers, by blowing or stretch-blowing blanks of plastics material, the term "blanks" meaning preforms obtained by injecting plastics material Formed parts, or intermediate hollow bodies obtained on the basis of preforms which have been subjected to at least one primary forming operation and which will be used for at least one secondary forming operation. [0002] More precisely, the invention relates to the thermal treatment of rough bodies, which is usually carried out by traveling in a treatment unit called a "furnace" equipped with a plurality of sources of electromagnetic radiation, driven around by a rough Blanks travel in front of these sources of electromagnetic radiation. Background technique [0003] A traditional heating technique consists in using incandescent lamps of the tubular halogen type, which emit on a continuous spectrum according to Planck's law...
