Abstract
Abstract A baler for making round bales is provided with a plurality of rolls and belts constituting a bale chamber having a crop inlet to which hay and the like is fed via a conventional pick-up mechanism. Two of the rolls are arranged as a set of first and second closely spaced apart, parallel rolls. Some of the belts are trained about only one roll of the set and about a group of common rolls in the baler. In one embodiment the other the belts are trained about both the first and second rolls and about the common rolls. The roll set is provided at the crop inlet in the area where the core of the bale is initiated. In a second embodiment the other belts are trained about only the second roll of the set and about the common rolls.
