Variable chamber round baler having a bale core formation chamber with a variable geometry, comprising at least a primary belt tensioner (15) and at least a secondary belt tensioner (16), whereby the primary belt tensioner (15) begins to act only after the bale core has been completely formed. Varying the initial geometry of the chamber and the compression program, it is possible to form bales having different properties, that is a hard or a soft core (with different diameters), a bale with constant density, etc.
