A machine (10) for forming material into cylindrical bales of density increasing from the center to the periphery, comprising a mobile structure (11) including first (14) and second (15) body portions pivotably secured together on a generally horizontal transverse axis, a baling chamber (20), in the structure, defined by portions of the peripheries of a plurality of closely spaced conveyors in the form right circular cylinders (21-39) mounted with their axes parallel and passing through points lying on a smooth closed curve in a vertical plane perpendicular to the axis, the lower half of the curve being generally a circular arc and the upper half departing outwardly from circularity by an amount which varies smoothly to and from a maximum in the vertical direction: a pickup mechanism (80-83) is provided for gathering material to be baled from the ground and introducing it as a ribbon peripherally into the chamber at its bottom, and a drive arrangement (17, 60-67, 70-73, 84, 85) is provided for causing operation of the pickup mechanism and the conveyors.
