Abstract
A large square baler includes a frame and a baling chamber for forming a bale. A support beam is attached to the frame and extends to a distal second end. A support structure is attached to the second end of the support beam. A track is attached to the support structure and includes an endless loop defining a path. A rotational drive is attached to the support structure and includes a crank rotatable about a rotation axis. An arm is coupled to the crank and includes an elongated slot. A carriage is attached to the arm and moves on the track along the path. The carriage supports a transverse face wrap roller for wrapping the transverse faces of the bale. A portion of the crank extends through and is moveable within the elongated slot such that a distance between the carriage and the rotation axis is variable.
