A buckle accumulator including an input feed system and for feeding a sheet in a path of travel and an output feed system located downstream in the path of travel from the input feed system. The sheet having a leading edge and a stiffness. The lead edge of the sheet is substantially unrestrained between the input feed system and the output feed system. The input feed system imparts a furrow within the sheet to increase the stiffness of the sheet between the input feed system and the output feed system so that the lead edge of the sheet substantially follows a desired path of travel and enters the output feed system.
