Installation for heating the bodies (1) of thermoplastic preforms (2) with a view to manufacturing containers by blow-moulding or stretch-blow-moulding, while the preforms (2) are being moved along with their bodies (1) following a predetermined path (T), this installation comprising at least one directional source (5) of electromagnetic radiation directed towards a location (E) on the path (T); the source (5) is inclined by an angle (α) of between about 60° and 10° and preferably less than about 45°, with respect to the tangent (6) to the path (T) at the location (E); thus, the electromagnetic radiation can pass through several preform bodies or parts of bodies without being appreciably reflected back towards the source (5).
Installation for heating the bodies of thermoplastic preforms with a view to manufacturing containers by blow-moulding or stretch-blow-moulding, while said preforms are being moved along in such a way that their respective bodies follow a predetermined path, this heating installation comprising at least one source of infrared electromagnetic radiation positioned to the side of the path followed by the bodies of the preforms and directed towards a location on said path, a reflector being positioned on the other side of the path opposite to the side where the source of electromagnetic radiation is positioned,
