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.

Knife assembly for net dispensing apparatus

A drive mechanism for a net dispensing apparatus used on a round baler wherein a resilient feed roller is operably driven by a drive belt powered from the main drive train for the round baler. A tensioning pulley is connected to a pivot arm pivotally mounted on the round baler and pivotally movable into and out of engagement with the drive belt by a linear actuator. The knife utilized to cut the netting material is interconnected with the pivot arm by a connecting link such that the pivotal rotation of the knife into and out of a cutting position is synchronized with the clutching and declutching of the feed roller drive. A lockout arm is also provided to engage a key on the shaft of the feed roller to positively restrain the feed roller from further rotation. The movement of the lockout arms is also synchronized to the movement of the tensioning pulley.
