ABSTRACT:
The machine forms bales of circular cross section by continuously rolling the bale upon a supporting surface within a formation chamber while additional material is supplied to the chamber. The chamber is partially defined by two separate, cooperating sets of flexible belts, one set having an upwardly moving stretch at the rear of the chamber and the other having a forwardly moving stretch defining the top of the chamber such that material entering the chamber at the beginning of the baling cycle is lifted upwardly by the rear stretch and rolled forwardly by the top stretch. The top and rear stretches converge to an upper rear corner of the chamber spaced above the supporting surface for the rolling bale, and such corner may be adjustably shifted vertically and/or horizontally in a fore-and-aft direction as may be necessary or desirable to facilitate bale starting under differing crop conditions. Alternative belt arrangements are disclosed for obtaining the desired adjustability of the chamber corner. An improved belt-tensioning assembly is also disclosed wherein spring tension on the belts is rendered substantially constant throughout the full movement of swinging arms that control and take up slack in the belts.
