A round baler (10) of the variable chamber type is provided with a pivot arm (14) having mobile rolls (20 c, d), which form loops (70) about stationary rolls (18 G, 18 H, 18 I) on side structures (32). The pivot arm (14) is journalled substantially above a bale chamber (36) and along its length and is able to pivot through an upper front area of the bale chamber (36).
