The apparatus including: a device for forming a buckle in the sheet, a mechanism for folding the sheet along the buckle, and an auxiliary feed path for directing the leading edge of the sheet out of contact with the folding mechanism and returning the sheet back to the buckle forming device. In the preferred embodiment, the folding mechanism includes a first folder roller and a second fold roller and the auxiliary feed path is race track shaped. Additionally, the auxiliary feed path may include: a first pathway, a second pathway which is longer in length than the first pathway and a gate for controlling whether the sheet enters the first pathway or the second pathway depending upon the length of the sheet.
