A portable, manually or motor operated machine for separating continuous multiple ply business forms into individual stacks, each having a single ply while simultaneously removing the carbon paper for disposal. The device includes a housing, a pair of separating rollers, a carbon paper winding reel that is manually or motor driven, and carbon sheet guide bars positioned strategically relative to the rollers which allow for efficient, rapid separation of the continuous business form. An attachable accessory allows separation of carbonless multiple ply business forms into two stacks of single plies. The drive shaft of the carbonless separator accessory replaces the carbon paper winding reel, and includes one or two pairs of belt driven wheels that rest on the separating rollers. The machine may be independently mounted on a table top, or be used in conjunction with a mateable floor stand.
