A method is provided for forming roll bales of crop material in a roll baler having upper and lower bale forming devices that cooperate with each other to define a bale starting zone. The upper bale forming device extends around an indexing guide member which has a home position for disposing the upper bale forming device proximate to the lower bale forming device at the rear of the bale starting zone. The indexing guide member is held in its home position while a roll bale is started in the bale starting zone. When the roll bale reaches a predetermined diameter, the indexing guide member is moved in a substantially circular path of travel generally about the periphery of the roll bale. The indexing guide member is subsequently returned to its home position and is held there again while the first-mentioned roll bale is disengaged from the baler and another roll bale is simultaneously started in the bale starting zone.
