Worm conveyor and press

A baler implement for forming a material into a bale having a cylindrical shape, the baler implement comprising:

• a plurality of rollers;
• a plurality of belts wound around the plurality of rollers to form a pressing chamber, the plurality of belts having an inner face configured for contacting the bale and forming a baling chamber during rotation about the plurality of rollers, and an outer face disposed opposite of the inner face and remote from the pressing chamber, such that the outer face does not contact the bale during rotation about the plurality of rollers;
• a worm conveyor disposed against the outer face of the plurality of belts for engaging crop material located on the outer face of the plurality of belts outside of the pressing chamber, the worm conveyor including:
• a roll having a peripheral surface and extending along a central longitudinal axis between a first front face and a second front face;
• wherein the roll includes a first edge region, a second edge region, and a central region disposed between the first edge region and the second edge region along the central longitudinal axis;
• wherein the first edge region and the central region join at a first collecting region, and the second edge region and the central region join at a second collecting region, whereby the central region is disposed between the first collecting region and the second collecting region;
• and
• a first screw flight and a second screw flight provided on the peripheral surface of the roll, wherein the first screw flight and the second screw flight wind in a spiral manner in opposing rotational directions about the central longitudinal axis and positioned such that the first screw flight moves crop material in the central region toward the second collecting region and the second screw flight moves crop material in the central region toward the first collecting region.
