Roll-Belt™ Design


The key to quickly forming perfect cores in any crop condition is New Holland’s proven combination of rolls and belts. The design of Roll-Belt balers utilizes heavy-duty steel rolls in both the front of the baler as well as in the floor of the bale chamber. The rolls are combined with short, tough belts in the back to deliver fast, consistent core formation and tight, uniform bales regardless of the crop you’re baling. This proven combination also forms the densest bales in the industry. By packing more of your valuable crop into each bale, you save time and money in numerous different ways.

From the moment you start baling to the moment the last bale is unloaded at your storage location, there are numerous benefits to making dense bales are many. Making fewer but denser bales in the field:
• Reduces ground compaction and plant damage, which promotes faster regrowth and higher tonnages for the next cutting.
• Reduces your baling time, and handling, wrapping, and transportation costs.
• Improves bale weathering and reduces loss because a dense bale sheds precipitation and resists absorbing moisture from the ground.
Density always matters.

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.
