A recyclable cushioning material for packaging obtained by forming a cushioning material for packaging used to protect articles supplied for physical distribution from being impacted with one sheet of corrugated fiberboard and a method and device for manufacturing the cushioning material, wherein a plurality of cutting lines (11 to 21) are formed in one sheet of corrugated fiberboard (10) in parallel with each other in the direction perpendicular to a direction in which the pleats of the corrugated fiberboard extend and a plurality of connection parts (25) are formed intermittently on each of these cutting lines so that a plurality of unit corrugated fiberboard (41 to 52) can be folded up alternately each other, openings (30 to 33) including the cutting lines are formed in the plurality of unit fiberboard (46 to 52) located on the inner side, and zig-zag foldings at the cutting lines (11 to 21) in which hump-folds and trough-folds are formed alternately each other are performed simultaneously by a zigzag folding device (70), and the pleats are glued with gluing nozzles (82, 83) and pressed by a cylinder (87) so as to connect and stack the unit corrugated fiberboard (41 to 52) to each other, where by the cushioning bodies for packaging (57 to 60) formed of a corrugated fiberboard stacked body having an article supporting part (55) can be assembled automatically.

Matière de rembourrage recyclable pour emballage utilisée pour protéger des chocs des articles destinés à être livrés, qui est formée à partir d'une feuille de carton dur ondulé, ainsi que procédé et dispositif de fabrication de ladite matière. Des lignes de coupe (11 à 21) sont formées dans une feuille de carton dur ondulé (10) parallèlement les unes aux autres dans un sens perpendiculaire au sens d'extension des plis du carton dur ondulé. Des parties de liaison (25) sont formées de manière intermittente sur chacune de ces lignes de coupe si bien qu'une pluralité de zones (41 à 52) de carton dur peuvent être pliées en alternance. Des ouvertures (30 à 33) incluant les lignes de coupe sont formées dans les zones (46 à 52) de carton dur situées sur le côté interne. Des plis en zigzag au niveau des lignes de coupe (11 à 21), constitués alternativement de plis en relief et de plis en creux, sont effectués simultanément par un dispositif de pliage (70) en zigzag. Les plis sont collés à l'aide de buses de collage (82, 83) et comprimés à l'aide d'un cylindre de manière à relier et à empiler ensemble les zones (41 à 52) de carton dur. Les corps de rembourrage (57 à 60) pour emballage formés d'un corps empilé de carton dur ondulé et possédant une partie (55) de support d'article peuvent être assemblés automatiquement.
