2 . The wrap film feeding assembly of claim 1 , wherein a pivot axis of the bracket is aligned with a rotational axis of a first bracket roller of the one or more bracket rollers.
3 . The wrap film feeding assembly of claim 1 , wherein the conveyor belt is coupled to a film delivery tray, and the film delivery tray is movably coupled to the frame.
4 . The wrap film feeding assembly of claim 3 , comprising one or more rear hold down strips, wherein the film delivery tray comprises a support bracket, the one or more rear hold down strips are coupled to the support bracket, and the support bracket is coupled to the film delivery tray.
5 . The wrap film feeding assembly of claim 4 , wherein the film delivery tray is moveable between a retracted position and an extended position relative to the frame.
6 . The wrap film feeding assembly of claim 1 , comprising an anti-back wrap bracket with one or more protrusions, wherein each of the one or more protrusions is engaged with a respective notch in the drive roller.
7 . The wrap film feeding assembly of claim 1 , comprising a mounting bar moveable vertically relative to the frame, wherein the roller tray is coupled to the mounting bar.
8 . The wrap film feeding assembly of claim 1 , wherein the bracket comprises a body and a mount, the one or more hold down strips are attached to the mount, and the mount is pivotally coupled to the body to control an angle of the one or more hold down strips relative to the body.
9 . A system comprising:
a frame;
a drive roller rotatably coupled to the frame and configured to convey a wrap film downstream toward a bale;
a belt assembly comprising one or more conveyor belts; and
one or more roller trays disposed above the belt assembly downstream from the drive roller, wherein each roller tray of the one or more roller trays comprises:
a bracket with a downstream end and an upstream end, wherein the bracket is pivotally coupled to the frame at the upstream end;
a plurality of bracket rollers rotatably coupled to the bracket; and
one or more hold down strips extending downstream from the downstream end of the bracket,
wherein the plurality of bracket rollers is configured to urge the wrap film against the belt assembly.
10 . The system of claim 9 , wherein a pivot axis of the bracket of each roller tray of the one or more roller trays is aligned with a rotational axis of a first bracket roller of the plurality of bracket rollers of the roller tray.
11 . The system of claim 9 , comprising an anti-back wrap bracket with one or more protrusions, wherein each of the one or more protrusions is engaged with a respective notch in the drive roller.
12 . The system of claim 9 , comprising a mounting bar that is moveable vertically relative to the frame, wherein the one or more roller trays are coupled to the mounting bar.
13 . The system of claim 9 , comprising one or more rear hold down strips disposed above the belt assembly.
14 . The system of claim 9 , comprising a film delivery tray movably coupled to the frame, wherein the film delivery tray comprises the belt assembly.
15 . The system of claim 14 , wherein the film delivery tray is moveable between a retracted position and an extended position relative to the frame.
16 . The system of claim 9 , wherein each roller tray of the one or more roller trays is laterally aligned with a respective conveyor belt of the one or more conveyor belts of the belt assembly.
17 . A roller tray for a wrap film feeding assembly, the roller tray comprising:
a bracket with a downstream end and an upstream end, wherein the upstream end is configured to be pivotally coupled to a frame of the wrap film feeding assembly, and the bracket is configured to be disposed above a conveyor belt of the wrap film feeding assembly;
one or more bracket rollers rotatably coupled to the bracket, wherein a first bracket roller of the one or more bracket rollers is positioned at the upstream end of the bracket; and
one or more hold down strips extending downstream from the downstream end of the bracket,
wherein the roller tray is configured to receive wrap film from a drive roller, the one or more bracket rollers are configured to contact the wrap film to urge the wrap film toward the conveyor belt, and the one or more hold down strips are configured to direct the wrap film toward a bale.
18 . The roller tray of claim 17 , wherein the bracket comprises a body and a mount, the one or more hold down strips are attached to the mount, and the mount is pivotally coupled to the body to control an angle of the one or more hold down strips relative to the body.
19 . The roller tray of claim 17 , wherein a pivot axis of the bracket is aligned with a rotational axis of the first bracket roller.
20 . The roller tray of claim 17 , wherein the first bracket roller is moveable vertically relative to the frame.
