Abstract: A closed edge corrugated core paperboard in which the corrugated core of the board is closed by slitting and compressing the corrugated core edge and by folding the edges of the facing sheets, left projecting after the core is crushed, one folded extending edge folded over the other folded extending edge, and adhesively securing the folded edges together; the method for producing such board including the steps of slitting and crushing the end of the core, folding the edges of the facing sheets, one over the other, and adhesively securing the folded edges of the facing sheets to each other; and, the apparatus for producing such board and for carrying out such method, which apparatus includes rotating slitter knives for slitting the end of the corrugated core, means for compressing the slit end and means for folding the extending facing sheet edges, one over the other, and for adhesively securing the folded edges to each other.
