Abstract
Abstract A rotary baler utilizing endless, driven belts to assist in formation of the bale has a tailgate that is raised for discharge of the bale after the forming cycle has been completed. A span of the belting is carried by the tailgate as the latter is opened, and a stationary tightener is positioned in the path of travel of the span during its movement with the tailgate so that the belting is progressively deflected in a transverse direction by the tightener as the tailgate continues to open, thereby tensioning the belting to forcefully eject the bale from the baler.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
138 words
In a rotary baler having a flexible web carried in part by a gate of the baler swingable to an open position for discharge of a finished bale from the baler, said web being disposed for driving engagement with the bale during formation thereof and continuing in contact with the bale until the latter is fully discharged, a bale ejecting improvement comprising: a web-tightening device disposed in the path of travel of the web as the latter is carried by said gate during movement to said open position thereof, said device being disposed to deflect said web transversely thereof during said movement of the gate whereby to apply an ejecting force to the bale through said web, said web being disposed out of substantial deflecting engagement with said device when the gate is in a closed position thereof.
Claim 2
Dependent Claim
138 words
In a rotary baler having a flexible web carried in part by a gate of the baler swingable to an open position for discharge of a finished bale from the baler, said web being disposed for driving engagement with the bale during formation thereof and continuing in contact with the bale until the latter is fully discharged, a bale ejecting improvement comprising: a web-tightening device disposed in the path of travel of the web as the latter is carried by said gate during movement to said open position thereof, said device being disposed to deflect said web transversely thereof during said movement of the gate whereby to apply an ejecting force to the bale through said web, said web being disposed out of substantial deflecting engagement with said device when the gate is in a closed position thereof.
