A sheet reversing apparatus is disclosed which includes a buckle chamber and input and output rollers which cooperate with a common roller respectively to form input and output nips for conveying a sheet into and out of the buckle chamber to reverse the lead and trail edge orientation thereof. The trail edge of the sheet is engaged by foam rolls coaxial with the common roller to transfer it from said input nip to said output nip and one or more fingers are arranged to urge the sheet trail edge into contact with the foam rolls.
