Bale wrapping device for a round baler

A round baler having a bale wrapping device, the round baler comprising:

• a drive roll which can be brought into engagement with a wrapping material roll;
• a drive and brake drum connected to and rotatable with the drive roll;
• a belt drive roll drivingly connected to a drive means for rotation;
• a drive belt placed around the drive and brake drum and the belt drive roll;
• an adjustment apparatus acting on the drive belt, wherein the adjustment apparatus includes an adjustment body partially disposed circumferentially around the drive and brake drum, and wherein the adjustment body is adjustable in the circumferential direction of the drive and brake drum to adjust the tension of the drive belt and a frictional connection between the drive belt and the drive and brake drum;
• a tensioning apparatus acting on the brake belt, wherein the tensioning apparatus is partially disposed circumferentially around the drive and brake drum, and wherein the tensioning apparatus is adjustable in the circumferential direction of the drive and brake drum to adjust a tension of the brake belt and a brake torque between the brake belt and the drive and brake drum;
• wherein the adjustment apparatus includes a guide part extending radially from the adjustment body relative to the drive and brake drum, wherein the guide part is partially disposed circumferentially around the drive and brake drum;
• wherein the tensioning apparatus includes a first curved guide arm and a second curved guide arm disposed parallel to each other and extending in the circumferential direction of the drive and brake drum;
• wherein the first curved guide arm includes a curved groove, and the adjustment body includes an adjustment groove;
• and
• wherein the tensioning apparatus includes an adjustment nut disposed engaging the curved groove of the first guide arm and the adjustment groove of the adjustment body.
