Abstract
An improved knotter primarily for use with a crop baling machine is disclosed. As is known in the art, a quantity of compacted crop material is encircled with a length of twine, or similar binding material, and a knot is tied in primary and secondary portions thereof to produce a discrete package of material. The improved knotter includes a rotatable twine holder for gripping the primary and secondary portions of twine and holding them in a side-by-side relationship extending along a predetermined path. A rotatable billhook is mounted adjacent the twine holder and positioned to intersect the predetermined path. Drive means interconnecting the twine holder and billhook rotate the two elements in timed relation such that during a first cycle of the billhook the twine portions are positioned thereabout, and during a second cycle of the billhook a knot is tied therein.
