HOW THE ROLL-BELT™ DESIGN WORKS
1) To start the process of making a bale, the pickup gathers crop from the ground. The floor roll feeds crop from the pickup into the belts. The floor roll also carries the majority of the bale’s weight, which reduces stress on the belts and lacings for longer life and lower maintenance costs. Constant action between the floor roll and the bale provides superior feeding compared to designs that feed directly from the pickup into the bale. Additionally, when a bale is being formed, its center of gravity is behind the centerline of the floor roll to allow bales to naturally fall out of the chamber when ejected, unlike competitive designs.
2) Next, the starter roll helps turn the crop and start the core. The ribs of the fixed roll aid in keeping the bale rotating. This roll also transmits power to the remaining upper rolls: the pivot roll, the ribbed stripper roll, and the follower roll. The function of the three rolls is to assist in rolling material and forming the bale’s core. The stripper roll is also ribbed to strip material off the apron belts and direct it back into the bale.
3) As the bale grows, the top rolls pivot forward. The belt tension arm (I) also rotates to allow the bale chamber to expand. The belt tension cylinder (J) and belt tension spring (K) deliver reduced belt tension at the start to ensure positive core formation, even when baling short, dry crop.
4) When the bale reaches full size, the tractor is stopped by the operator. The wrapping mechanism starts automatically.
