In a large round baler including a bale-forming chamber having opposite sidewalls and a transverse opening extending the full width of said chamber between said sidewalls, said bale-forming chamber including a rotating element having an arcuate profile defining one side of said opening and including a rotatable roll having opposite ends extending outwardly beyond said opposite sidewalls, a net wrapping mechanism adapted for introducing net material, having a width greater than the distance between said opposite sidewalls, over said roll and through said opening for introduction into a nip defined by a rotating bale just formed in the chamber and said arcuate profile, whereby the net material will be carried into said bale-forming chamber, a pair of bale end engaging structures respectively extending inwardly from vertical, planar inner surface portions of said opposite sidewalls in the vicinity of said roll, each bale end engaging structure having a leading and a trailing edge relative to the direction of rotation of a bale in said chamber, a passage leading from a location outward of a given sidewall adjacent the roll to a location inwardly of said given sidewall adjacent the trailing edge of the adjacent bale end engaging structure, and a pair of net spreader elements being carried by said roll respectively in bridging relationship to said opposite sidewalls, the improvement comprising:
- said pair of net spreader elements each including a spreader ring including at least one wedge-shaped notch having first and second sides converging outwardly from an inner end of said notch;
- said first side of said notch trailing said second side when considered relative to a direction of rotation of said roll during normal operation and being located for engaging longitudinal strands of outer marginal portions of said net material at or inside said planar inner surface of the adjacent sidewall and angled outwardly for moving these strands outwardly of said inner surface, whereby the net material is spread to a width greater than that of said bale-forming chamber.
