<p>An improved net cutting assembly (12) that may be used with an agricultural baler net wrapping system. More particularly, an up-cut net knife (60) for improved cutting of wrapping material (e.g., a net) used to wrap bales of crop material in an agricultural baler. The up-cut net knife assembly improves net cutting performance by providing an up-cut net knife that moves in the same direction as the net whereby the motion of the net helps the knife get into the cut position. Further, embodiments of the up-cut knife assembly move the up-cut knife cutting edge at substantially the same speed and in the same direction as the net to be cut. This motion of the up-cut knife allows the up-cut knife to be lifted up into the net motion using a driver (67) and then to continue on with no relative motion - or at least minimal relative motion of the knife to the net - until the knife gets into the cut position. In the cut position, the knife (60) stops and the net is pulled against the knife blade resulting in cutting the net.</p> |
