ABSTRACT:
A knife assembly for a net dispensing apparatus used on a round baler is disclosed wherein the knife assembly is moved into a cutting position engageable with the netting material without imparting impact energy into the netting material. The knife assembly includes a knife holder having a curved portion wrapped concentrically around a pivot shaft and a detachable knife member. When the knife assembly is moved into a cutting position, the netting material forms an angle around the cutting edge of the knife member with a portion of the netting material extending generally parallel to the plane of the plane of the knife member. The tension applied to the netting material by reason of the net dispenser feed roll being halted and the cylindrical bale continuing in rotation pulls the netting material across the cutting edge of the knife member to effect a severance thereof.
