ABSTRACT:
An automatic bale wrapping assembly for a machine that forms round bales of windrowed crop material and includes a mobile main frame with a bale forming assembly operative to continue rotating a completed bale while a wrapping twine is wound thereon, and a pickup mechanism for supplying such material to the bale forming assembly. The bale wrapping assembly has an extendible and retractable elongated twine dispensing arm having a pair of sections longitudinally movable relative to each other from one of which extends a free end section of the wrapping twine. The dispensing arm is pivotally supported on the main frame for movement between an initial bale wrapping position and a final twine cutting position. A control arm and hydraulic cylinder coact with the dispensing arm for relatively moving the pair of dispensing arm sections during pivotal movement of the dispensing arm, so that it is retracted in the initial bale wrapping position and extended in the final twine cutting position whereby a greater length of the twine free end section is exposed in the retracted position than is exposed in the extended position.
