Feed rollers for round baler net dispenser

In a round baler utilized for making cylindrical bales of crop material and having a wheeled frame adapted for movement over the ground;

• a pair of transversely spaced apart, generally vertical side sheets supported by said frame;
• bale forming means movably supported between said side sheets for forming a cylindrical bale of crop material;
• and a net dispensing means positioned adjacent said bale forming means for selectively dispensing netting material from a source of supply of said netting material into said bale forming means from a source of supply of said netting material into said bale forming means so that a finished cylindrical bale of crop material can be wrapped therearound with said netting material, an improved net dispensing means comprising:
• a driven transverse feed roller journalled between said sheets and a pair of movable, transversely extending rotatable pinch rollers engageable with said feed roller along the transverse length thereof, said pinch rollers being movable away from said feed roller to permit the introduction of netting material therebetween, said pinch rollers being movable into engagement with said feed roller to pinch said netting material therebetween and permit a feeding thereof into said bale forming means, one of said pinch rollers being mounted between transversely spaced plates and being positioned on one side of said feed roller, the other said pinch roller being rotatably journaled between a pair of pivot arms which are pivotally connected to the corresponding said plate to permit a movement of said other pinch roller relative to said feed roller and said one pinch roller, said other pinch roller being positioned on the opposing side of said feed roller, each said plate being slidably mounted on the adjacent side sheet, said pivot arm being connected to an overcenter linkage to effect a pivotal movement thereof into a position in which said other pinch roller is engaged with said feed roller so that any subsequent pivotal movement of said pivot arm will effect a sliding movement of said plate to draw said one pinch roller into engagement with said feed roller.
