Abstract
Abstract A machine for continuously forming roll bales of crop material has a lower apron and forward and rearward upper aprons cooperating to define front and rear bale forming chambers. A rotatable arm assembly supports the rearward upper apron, and a control linkage is provided for holding the arm assembly in a position so that it does not interfere with the discharge of a bale from the rear chamber.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
In a roll baling machine having a lower apron, a first upper apron cooperating with said lower apron to define a front bale forming chamber, a second upper apron cooperating with said first upper apron to define a rear bale forming chamber, an arm assembly supporting part of said second upper apron, said arm assembly being rotatable from a first position when said rear bale forming chamber is empty to a second position during formation of a roll bale in said rear bale forming chamber, the improvement comprising: control means for holding said arm assembly in said second position while a roll bale is being discharged from said rear bale forming chamber, and said control means including a link member having a lost-motion connection with said arm assembly as said arm assembly moves between said first and second positions.
