Zusammenfassung:	A tri-fold machine and process to fold up compressed high expansion force material. The machine includes a left-side horizontal conveyor and a right-side horizontal conveyor with a middle conveyor therebetween. A pair of longitudinal bars are operable between (i) a raised position and (ii) a lowered position. The right-side and left-side conveyors are each movable between a horizontal home position and a folding position. A middle portion of the material is held in longitudinal gaps formed on each side of the middle conveyor. A left side of the material is folded over the middle portion of material. A right side of the material is folded over the left side of the material which is over the middle portion.
