Zusammenfassung:	A radiant energy device for shrinking a thin film (20) onto an open top of a container (14), the radiant energy device comprising: a source of power (27), to provide power to the radiant energy device; a plurality of fixed energy-emitting units (12), each of the units when energized being configured to emit radiant energy towards the shrinking film on said open top of the container; and a switching means (22), operatively connected between the source of power and each of the energy-emitting units, to independently activate at least two groups of the energy-emitting units; wherein, a first group of the energy-emitting units partially shrinks the thin film onto the container, and a second group finishes the shrinking. A radiant energy device for shrinking a thin film onto an open top of a container, the radiant energy device comprising: a source of power, to provide power to the radiant energy device; a plurality of fixed energy-emitting units, each of the units when energized being configured to emit radiant energy towards the shrinking film on said open top of the container; and a switching means, operatively connected between the source of power and each of the energy-emitting units, to independently activate at least two groups of the energy-emitting units; wherein, a first group of the energy-emitting units partially shrinks the thin film onto the container, and a second group finishes the shrinking. L'invention concerne un dispositif à rayonnement de rétrécissement d'un film mince sur la partie supérieure ouverte d'un récipient, ledit dispositif comprenant une source d'alimentation servant à alimenter le dispositif à rayonnement; une pluralité d'unités fixes d'émission d'énergie, chacune des unités énergisées étant configurée pour émettre un rayonnement en direction du film de rétrécissement sur ladite partie supérieure du récipient; et une unité de commutation, connectée entre la source d'alimentation et chacune des unités d'émission d'énergie, pour activer indépendamment au moins deux groupes d'unités d'émission d'énergie. Un premier groupe d'unités d'émission d'énergie rétrécit partiellement le film mince sur le récipient, et un second groupe finit le rétrécissement.
