ABSTRACT:
A net dispensing mechanism for a round baler is disclosed wherein a pair of pinch rollers are cooperable with a driven feed roller to feed netting material from a source of supply into the bale forming mechanism of the round baler so that the finished round bale can be wrapped with an external layer of netting before being ejected from the baler. The pinch rollers are mounted on opposing sides of the feed roller and are adjustable relative thereto to permit proper engagement of both pinch rollers with the feed roller to allow proper feeding of net therebetween. An overcenter linkage is connected to the mechanism mounting the pinch rollers to affect a movement of the pinch rollers between engaged and disengaged positions for selectively permitting the threading of net between the pinch rollers and the feed roll. One embodiment has both pinch rollers mounted on a pivot arm which is pivitally mounted on an eccentric to permit an adjustment of the position of the pinch rollers relative to the feed roller. Another embodiment utilizes a sliding plate fixedly mounting one pinch roller and pivotally mounting a second pinch roller via a pivot arm to permit a clamping of the pinch rollers against the feed roller.
