Abstract
A roll forming crop baling machine to produce more even bale density, which forms the bale by use of rigid rollers. The set of rollers, one stationary set and another shifting set, are used to form and compress the bale during a major portion of its growth. Each shifting roller gradually moves outward from an initial position near the core of the forming bale which is radially inward from the stationary rollers, to a final position forming a continuous outer boundary with the stationary rollers.
Claims7
In a round baler machine for forming cylindrical bales of windrowed agricultural crop material comprising a wheel mounted frame, power means and means for raising the crop onto the frame and into contact with multiple rotating rollers which impart motion to the crop material to form a bale of cylindrical shape completely enclosed within the machine, the improvement comprising:
- means for shifting at least a portion of the rollers from a closely grouped position at the beginning of the formation of the bale to a position of expanded grouping as the final size of the bale is reached;
- and means for restraining the shifting rollers in their expansion paths to create compressive force on the bale wherein the final expanded grouping position of the shifting rollers is such that they act in cooperation with the stationary rollers to rotate and compress the bale in its final size and position.
