Abstract
Abstract A mechanism for wrapping a plastic cover sheet about a round bale of hay is incorporated in a round bale forming machine. The mechanism includes an arbor for receipt of a roll of wrapping material. The arbor is positioned in the bale forming machine forward of the bale forming mechanism. The wrapping material is fed from the roll and wraps about the formed round bale as the baling machine moves forward. After the wrapping material encircles the bale, it is cut. The cut end is overlapped on the wrapped bale and glued thereto. Various wrapping material feed and cut off mechanisms are disclosed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
206 words
In a round baler of the type having a bale forming mechanism for transport over a field of cut material to gather and form the material into a round bale, the improvement of apparatus for applying a cover sheet over the round bale during the bale forming operation, said improvement comprising in combination: (a) a wrapping material roll storage member affixed to the baler forward of the bale forming mechanism, said roll storage member being oriented to position an end of a sheet of wrapping material on the roll member in the path of the cut material for wrapping the bale as the bale is being formed; (b) drive means for the storage member for removing the sheet of wrapping material from the roll member and directing the end of said sheet along the ground for gathering by the bale forming mechanism about the outside surface of the formed bale; (c) means forward of the bale forming mechanism for terminating flow of cut material to the bale forming mechanism; (d) means for cutting the wrapping material intermediate the bale forming mechanism and the roll storage member; and (e) means for affixing a cut end of sheet material to a bale formed by the bale forming mechanism.
Claim 2
Dependent Claim
206 words
In a round baler of the type having a bale forming mechanism for transport over a field of cut material to gather and form the material into a round bale, the improvement of apparatus for applying a cover sheet over the round bale during the bale forming operation, said improvement comprising in combination: (a) a wrapping material roll storage member affixed to the baler forward of the bale forming mechanism, said roll storage member being oriented to position an end of a sheet of wrapping material on the roll member in the path of the cut material for wrapping the bale as the bale is being formed; (b) drive means for the storage member for removing the sheet of wrapping material from the roll member and directing the end of said sheet along the ground for gathering by the bale forming mechanism about the outside surface of the formed bale; (c) means forward of the bale forming mechanism for terminating flow of cut material to the bale forming mechanism; (d) means for cutting the wrapping material intermediate the bale forming mechanism and the roll storage member; and (e) means for affixing a cut end of sheet material to a bale formed by the bale forming mechanism.
Claim 3
Dependent Claim
56 words
The improvement of claim 1 wherein said bale defines an axis of rotation during formation and wherein said roll storage member comprises a roll mounting assembly for supporting a cylindrical roll of wrapping material for rotation about a roll axis parallel to the axis of rotation of the round bale during formation of the round bale.
Claim 4
Dependent Claim
28 words
The improvement of claim 1 wherein the drive means comprise means for directly driving the roll storage member to thereby unroll wrapping material from the roll storage member.
Claim 5
Dependent Claim
33 words
The improvement of claim 1 wherein said drive means comprise opposed, parallel drive rolls on opposite sides of the wrapping material for gripping and removing the wrapping material from the roll storage member.
Claim 6
Dependent Claim
19 words
The improvement of claim 4 wherein one of said drive rolls is spring biased toward the other drive roll.
Claim 7
Dependent Claim
37 words
The improvement of claim 4 wherein said drive rolls are mounted on a bracket for movement about the roll storage member, whereby the wrapping materials may be positioned with respect to the formed bale by bracket movement.
Claim 8
Dependent Claim
40 words
The improvement of claim 1 wherein said means for terminating the flow of cut material comprise a rake member attached to the baler and means for positioning the rake member in the path of travel of the bale forming mechanism.
Claim 9
Dependent Claim
44 words
The improvement of claim 1 wherein the means for cutting comprises a blade member on the baler intermediate the roll storage member and the bale forming mechanism, and blade actuation means for imparting the blade against the wrapping material to cut the wrapping material.
Claim 10
Dependent Claim
35 words
The improvement of claim 1 wherein said means for affixing include adhesive discharge means for applying adhesive to the wrapping material whereby the wrapping material may be made to be attached about the formed bale.
