A folding apparatus utilizes a primary drive motor, at least one cylinder that is driven for rotation by the primary drive motor, and a pair of folding rollers. The folding rollers can be driven for rotation by an auxiliary motor. The folding rollers can be coupled to the rotation of the cylinder by a differential drive that includes three drive take-off members. One of these is connected to each of the cylinder, the auxiliary motor, and the folding rollers.
