To provide a rack for corrugated board, capable of orderly storing flatly folded corrugated board sheets in a laterally arranged state and easily binding the stored corrugated board sheets while compressing them under the stored condition, thus serving for the recycling of corrugated board.

Side guards 2, 3 are opposingly provided on a base 1. The side guards 2, 3 are mounted on portions of the base 1 so as to be freely flapped with the aid of hinges 11, 12 and are made to be capable of being laid flat in a mutally opposed direction from an upright state, respectively. The side guard 2, which is one of the side guards, is mounted to a travelling stand 6 sliding along guide rails 5 as a movable side and is made to be movable toward the other side guard 3. Flatly folded corrugated board sheets are made to stand against the side guards 2, 3 in a laterally arranged state between both the side guards 2, 3 and, at a stage that the stored amount thereof reaches a suitable amount, they can be easily bound with a pressure sensitive adhesive tape or the like while being compressed in the direction of their thickness by the movement of the side guard 2.
