The invention concerns a continuous packaging technique whereby a volume of compressible material is compressed between two convergent conveyors, the volume being initially placed and driven during the compression between two continuous packaging film strips, mutually linked on either side of the volume once the required degree of compression has been reached. The invention is characterised in that after having left between two consecutive volumes a length L of packaging film on each strip, the distance between the rear end of a first volume and the front end of the next volume is adjusted such that it is equal to the length L at the time when the two strips are mutually tied in the packaging step. The invention is useful for conditioning insulating products based on mineral wool.
L'invention a trait à une technique de conditionnement en continu dans laquelle un volume de matériau compressible est comprimé entre deux transporteurs convergents, le volume étant placé initialement et entraîné au cours de la compression entre deux bandes continues de film d'emballage, qui sont liées l'une à l'autre de part et d'autre du volume une fois atteint le degré de compression désiré. Selon l'invention, en ayant laissé entre deux volumes consécutifs une longueur L de film d'emballage sur chaque bande, on ajuste la distance entre l'extrémité arrière d'un premier volume et l'extrémité avant du volume placé à sa suite, de façon à ce qu'elle soit égale à la longueur L au moment de lier les deux bandes entre elles dans l'étape d'emballage. Application au conditionnement de produits isolants à base de laine minérale.
