An apparatus for folding sheet material comprises a rotatable magazine comprising two folding plates having end edges extending parallel to each other for holding the sheet material with portions thereof projecting beyond the edges of the folding plates, and two folding rams wherebetween the rotatable magazine is mounted and which are displaceable with respect to each other, each folding ram having a substantially planar guide face facing the magazine and for guiding the projecting sheet material portions and cooperating with the end edges of the folding plates for bending the sheet material along the end edges upon rotation of the magazine. The magazine is rotatable 180 DEG from a receiving position for the sheet material wherein the guide faces extend adjacent and substantially parallel to the folding plates, to a middle position wherein the guide faces extend substantially perpendicularly to the folding plates, and to a discharge position for the folded sheet material wherein a respective one of the projecting sheet material portions is bent about a respective one of the folding plate edges and the guide faces again extend adjacent and substantially parallel to the folding plates, the folding rams being in contact with the magazine in the receiving and discharge positions and rotation of the magazine causing the folding plates to be pressed apart.
