Abstract
In a crop roll forming machine having a mobile frame, a pickup, a crop material conveying apparatus, a bale forming apparatus, and a bale forming region defined generally by the bale forming apparatus and the frame there is provided an improved tensioning apparatus for the bale forming apparatus comprising at least a first and a second spring extensibly affixed to mounting structure at a first end and connected to the bale forming apparatus at a second end. The springs further have an easily adjustable tension adjustment so that a resistive force to the extension of the springs is generated in direct relationship to the adjustments made to the tension adjustment; the resistive force being transmitted to the bale forming apparatus at the second end thereby providing an adjustably increasing tension to the bale forming apparatus and correspondingly adjustably increasing the force exerted upon crop material being formed into a bale in the bale forming region.
