An apparatus for forming filled dough products. The apparatus includes a first belt conveyor and a second belt conveyor located below and at the end of the first belt conveyor. A first air jet stream is discharged through a thin rectangular orifice against the underside of a sheet of dough carrying a cylindrical filling as the sheet of dough leaves the first belt conveyor to support the leading edge of the sheet of dough. A deflector engages the leading edge of the sheet of dough to bend the corner thereof upwardly. A second air jet stream discharges through a thin rectangular orifice against the sheet of dough to reversely fold the leading corner of the sheet of dough against the cylindrical filling and also bends the trailing edge of this sheet of dough onto the second conveyor belt after the sheet of dough and the filling have dropped to the second belt conveyor. Rollers crease the sheet of dough outwardly of the cylindrical filling. A third air jet stream discharges through perforations positioned on opposite sides of the second belt conveyor to lift the opposite corners of the sheet of dough about the creases and to fold the corners inwardly over the filling. A paddle blade creases the folded dough rearwardly of the filling. An overhead belt conveyor moving opposite to the second belt conveyor completes the rolling of the dough and filler.
