ABSTRACT:
The invention relates to knotters for tying knots and has particular, but not exclusive, application to agricultural balers. In known baler knotters, twine for tying the bales is cut by a fixed or movable knife in such a way that substantially the same portion of the knife edge is used for cutting with the result that early blunting occurs which can give rise to only partially cut twine which adversely affects the knotter. In accordance with the invention a knotter (24) comprises a twine holder (63) operable to hold, during a knot-tying operation, a primary and a secondary portion (20,43) of twine in which the knot is to be tied, and rotary knife means (130) operable to cut at least one of said twine portions at a predetermined point in the operational cycle of the knotter and as said at least one twine portion is held by the twine holder.
