Abstract
Method and apparatus for delivering twine to a baler knotter. The baler (10) which performs the method includes a bale chamber (16) having a forward inlet end. A knotter (64) is disposed to one side of the bale chamber and the baler is of the type having feeding means including a pair of rollers (36) which are moved back and forth across the inlet end of the bale chamber. A portion (90) of the twine is supported on the lower feed roller as the rollers are moved back and forth across the inlet end of the bale chamber. A pickup needle (110 or 302) is associated with the knotter, and at the initiation of the tying cycle moves from an at rest position towards the lower roller to pick up the twine and then to a position above the twine disks (140) of the knotter to deliver the twine to the knotter and then returns to its at rest position. The twine is tensioned by a twine drag (144) and a pigtail type tensioning mechanism (146) both during the formation of a bale and during tying.
