Patent ID: 8635951

Claim:
A baler for manufacturing bales of harvested crop material, the baler comprising: a bale chamber comprising a first part having a fixed configuration, and a second part comprising four sides defining a substantially rectangular opening through which a bale is urged along a bale travel axis from a front end inlet opening towards a rear end outlet opening, the four sides comprising a pair of chamber doors arranged along two opposing sides of the bale chamber, each of said pair of chamber doors being pivotably connected at one end to the first part of the bale chamber and extending rearwards therefrom in a manner to allow the pair of chamber doors to be selectively pivoted inwards and outwards relative to the bale travel axis, wherein at least one of the chamber doors comprises at least two side sections which are pivotally connected relative to one another, thus defining a door angle at a pivotable connection; a configuration selector for obtaining at least one crop parameter and for selecting a door angle value for the bale chamber in accordance with the obtained crop parameter to thereby establish a suited pressure profile to be exerted upon the bale being compacted while moving through the bale chamber during bale manufacturing; and means for changing the position of the side sections with respect to one another so as to include the selected door angle value between them.
