Abstract

Selon l'invention, une pellicule de matière plastique 12 de grande largeur, plus de 3 m par exemple, descend entre des rouleaux d'alimentation 1 et 2 dans un poste de pliage 23 où elle est pliée en accordéon et transformée en un paquet par des jets d'air comprimé 17 et 18 de rampes latérales 9 et par des patins presseurs 7. Le paquet est formé sur un transporteur 11 qui reste stationnaire jusqu'à ce que le paquet soit terminé et qui le décharge ensuite sur une table fluidisée 10, le poids du paquet pouvant atteindre 100 kg.According to the invention, a plastic film 12 of great width, more than 3 m for example, descends between feed rollers 1 and 2 in a folding station 23 where it is folded like an accordion and transformed into a bundle by compressed air jets 17 and 18 of side ramps 9 and by pressure shoes 7. The package is formed on a conveyor 11 which remains stationary until the package is finished and which then unloads it on a fluidized table 10 , the package weight up to 100 kg.
