Title: Breakaway mechanism for an improved crop material roll forming machine

Abstract: A breakaway mechanism mounted on the frame of an improved crop material roll forming machine engages a take-up and expansion member to cause the member to initially retain an upper flexible, roll-forming apron substantially in a contracted position as crop material, being initially rolled to form a core at a roll-forming area defined between the upper apron and a lower crop-conveying and roll-forming apron, builds to a desired predetermined density. The breakaway mechanism will release its engagement with the take-up member when the core of crop material reaches the desired predetermined density.
