CONTINUOUS ROLL BALER

摘要

A continuous roll baler includes upper and lower bale forming devices (66, 28) that cooperate with each other to define a bale starting zone (69), and a pickup device (20) to deliver crop material toward the bale starting zone (69). The upper bale forming device (66) preferably constitutes a series of belts extending around a drive member (40) and a plurality of guide members, (42, 44, 46, 48, 64, 50, 60, 52, 54, 56, 58, 72) one of which is an indexing guide member (72) located in a home position to guide the upper bale forming device (66) proximate to the lower bale forming device (28) at the rear of the bale starting zone (69). The baler further includes means such as a pair of disks (68) for moving the indexing guide member (72) from its home position in a substantially circular path of travel when a roll bale was started in the bale starting zone (69), reaches a predetermined size. Drive means such as sprockets (76) are provided for engagement with the peripheral edges of the disks (68) to rotate these disks (68) in a direction to cause said movement of the indexing guide member (72). Also a method is provided for continuously forming bales of crop material in a roll baler of this type.
