Abstract
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 zig-zag 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 e…
