Title: Round bale forming roll

Abstract: A round baler for forming crop material into cylindrical bales. The baler has a main frame, a pair of side walls, a crop pickup mounted on the main frame, and a tailgate pivotally connected to the main frame. The tailgate is operative between a closed position during which a bale is being formed in an expandable chamber, and an open position during which a formed bale is being discharged from the chamber. A sledge assembly, pivotally mounted on the main frame for movement between a bale starting position and a full bale position, has crop engaging transverse rolls for urging the crop material along a spiral path in the chamber for starting and forming a bale. A apron is supported along a continuous path on the main frame and tailgate by a plurality of rotatable guide members. The path has an inner course that cooperates with the sledge rolls on the sledge assembly to define moveable walls of the chamber. A drive roll moves the apron along the continuous path. One of the transverse rolls on the sledge has a plurality of flaps that extend into the space between and has intermittent contact with the apron as it travels in the vicinity of the outer surface of the transverse roll. This prevents leakage of stray crop material from the space between such roll and the apron under conditions where a cylindrical package of crop material is being formed in the chamber.
