AbstractA sheet folding apparatus comprises a substantially planar surface for receiving and supporting a substantially rectangular extended sheet. The apparatus includes a first folder for folding the substantially rectangular extended sheet along a first diagonal axis thereof to form a once folded sheet defining a long base, a second folder for folding the two halves of the base of the once folded sheet towards each other and into parallel disposition with an axis transverse to the axis of the base to form a twice folded sheet, and a third folder for folding the two halves of the twice folded sheet along a second diagonal axis thereof to form a thrice folded sheet while simultaneously removing the sheet from the substantially planar surface.
