Abstract
In a round baler, twin arms come together in the start position, on the side opposite the cut position, because that configuration ensures that two twines lie nearly on top of each other to secure the bale much better at that end than with a single twine. The “start position” refers to that position where the twine arms reverse direction, and change from a fast speed of travel used to move the twine arms across the bale width, to a slower, controlled speed that is adjustable to vary the spacing of the twines. The change in direction combined with bringing the twine arms together at the start position, ensures that loose twine ends are effectively restrained as the twines are applied.
