Claim:
A baler including a baling chamber having transversely spaced first and second sides and a double twines arm assembly for dispensing twine for wrapping a large cylindrical bale located within the bale chamber, said twine arm assembly comprising: a first twine arm including a first twine dispensing end being pivotally mounted for oscillation about an axis to sweep a path between first and second locations respectively disposing the first twine dispensing end thereof adjacent the first and second sides of the chamber for wrapping the twine on a bale being formed in the baling chamber, the bale having a width extending from the first side to the second side of the chamber; a second twine arm pivotally attached to the first twine arm including a second twine dispensing end and being mounted for oscillating in a path at least adjacent to the path swept by the first twine arm; a reversible drive coupled to said first twine arm for oscillating the first twine arm between said first and second locations; a spring, having a biasing force, operatively attached to the first and second twine arms for biasing the second twine dispensing end of the second twine arm to a first position away from the first twine dispensing end and permitting the second arm to pivot to a second position wherein the second twine dispensing end of the second twine arm is closer to the first end of the first twine dispensing end than in the first position thereof; a stop operatively attached to and located at a place on the baler for engaging the second twine arm to stop the second twine arm from moving toward the first location while the first twine arm continues to move toward the first location, thereby moving the second twine arm end to move closer to the first twine dispensing end in opposition to the biasing force of the spring; and the baling chamber has a twine starting side on the first side of the chamber and a twine cutting side on the second side of the bale chamber and the stop is located adjacent the starting side, a first distance between the first twine dispensing end of the first twine arm and the second twine dispensing end of the second twine arm when the first and second twine arms are at the twine starting side is significantly less than a second distance between the first twine dispensing end of the first twine arm and the second twine dispensing end of the second twine arm when the first and second arms are at the twine cutting side of the chamber, a position adjustable finger on the twine cutting side of the bale chamber for engaging the twines to limit the twines from wrapping to the end of the bale.
