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 each other, whereby 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.
