Baler Knotter
How It Works
Well, if you really want to know: An automatic tie system for a baler for tying a bale of compressible material comprises a reciprocating ram for pushing the bale along a path. A continuous strand of baling wire extends generally transverse to the path and engages the bale front end and wraps around the bale as it moves along the path. A reciprocating inserter arm engages the continuous wire strand to form a partial loop at the bale back end having an apex and an upstream wire section and a downstream wire section. A first gripper arm grips the upstream loop section when the loop is cut and moves the upstream loop section generally parallel to an incoming section of wire from a baling wire supply roll to create a supply wire overlap. A second gripper arm grips the downstream loop section and moves it adjacent to the bale and generally parallel to wire from a baling wire supply roll to form a bale wire overlap. A twisting mechanism engages the bale wire overlap and supply wire overlap and twists the overlaps to tie the bale with two in-line twists which have opposite hand twist orientations and lie generally flat against the sides of the bale. Another opposite hand twist reforms the continuous strand of baling wire. http://www.freepatentsonline.com/5870950… Now, I have to admit that I really can't follow all of that real well, but could work on'em when they fouled up, or get it going again when it broke a wire. Also grease and oil it when it needed it. The twine knotter was a little before my time (or before the time when we used them), I know some are still being used, but very few I think. The newer round balers just wrap the bale with twine and doesn't tie a knot.
