A system for forming a bale bundle that includes a preselected number of columns of bales, each column including a predetermined number of the bales. The system includes an injector for moving the predetermined number of the bales in a predetermined injection sequence into a loading chamber. In the predetermined injection sequence, the injector moves a preselected number of the bales into the chute and subsequently moves the predetermined number of the bales into the loading chamber. The system also includes a plunger assembly for moving columns of the bales positioned in succession in the loading chamber into the compression chamber in a predetermined assembly sequence, until the preselected number of the columns is in the compression chamber. The plunger assembly compresses the preselected number of columns while a knotter assembly ties the columns together to form the bale bundle, and the injector recommences the predetermined injection sequence.

A baler has a dispensing arm movably mounted to a frame and configured to dispense twine to wrap a bale of crops. The bale has a first end, a second end, a center, and a rotation axis extending along a longitudinal axis of the bale. The twine arm is moveable between a stowed position, a first position near the first end of the bale, and a second position near the second end of the bale. A controller is operatively coupled to the dispensing arm to control movement of the dispensing arm between the first end, a first and second catch position, and the second end. The controller is programmed to move the dispensing arm with a fast stroke at portions of the bale and a slower apply stroke a different portions of the bale to wrap the bale with twine having consistent spacing along the longitudinal axis of the bale.
