Claim:
A case erector, for erecting a case, the case erector comprising: a planar bearing surface within which is defined a semi-circular channel about a center point, wherein a notch is defined in the planar bearing surface to allow a fold between adjacent sides of the case to be erected to be located at the center point; a plate in contact with the planar bearing surface, the plate having at least one flange, wherein the at least one flange is sized for travel within the semi-circular channel so that the plate rotates against the planar bearing surface in a circular manner about the center point and wherein a notch is defined in the plate to allow the fold between adjacent sides of the case to be erected to be located at the center point; and an arm connected to the plate, wherein the arm rotates in concert with the plate and wherein the arm has at least one attachment device configured to attach to one of the adjacent sides of the case to be erected; and a second arm connected to a second plate moving against a second planar bearing surface, wherein the second plate has at least one attached flange moving in a semi-circular channel defined in the second planar bearing surface; wherein the first and second arms each rotate 45 degrees between an open position and a closed position.
