PCT No. PCT/IT96/00114 Sec. 371 Date Jan. 6, 1998 Sec. 102(e) Date Jan. 6, 1998 PCT Filed Jun. 4, 1996 PCT Pub. No. WO97/03550 PCT Pub. Date Feb. 6, 1997A variable chamber round baler having a bale core formation chamber with a variable geometry including a primary belt tensioner and a secondary belt tensioner, the primary belt tensioner begins to act only after the bale core has been completely formed; varying the initial geometry of the chamber and the compression program allows the formation of bales having different properties, such as a hard or soft core (with different diameters), a bale with constant density, etc.
