Abstract
In a mobile machine for forming cylindrical bales, a mat of crop material is picked up from the ground and fed to a baling chamber defined by the generally horizontal upper run of a lower endless belt conveyor and the internal envelope of a plurality of rollers carrying an upper conveyor and disposed immediately above it. The upper conveyor comprises a plurality of elastic endless belts stretched around the rollers and includes a lower run which, at the inception of bale formation, spans the baling chamber between a pair of lower rollers immediately above the chamber floor. The upper and lower conveyors are driven in opposite directions so that as the mat of crop material is fed into the baling chamber, it is rolled, spiral-like, into a cylindrical bale. As the bale increases in diameter, the belts of the upper conveyor, engaging the bale periphery, extend elastically to provide the increase of belt length required to accommodate the bale in the chamber.
