专利汇可以提供Apparatus for wrapping bagging and the like about bales of fibers专利检索，专利查询，专利分析的服务。并且Apparatus adapted for association with the upper and lower platens of a baling press or the like and effective to wrap sheets of material about portions of a bale while under compression between the platens. The wrapping mechanism on the platen which passes into and through the fiber collection box or chamber of the press mechanism is designed to retract behind the fiber engaging surface of such platen and to lie within the vertically projected confines thereof, permitting such platen to traverse the box without interference by such mechanism. The mechanism comprises sheet engaging arms disposed when actuated to crease and fold the sheets about the ends and sides of the bale while the bale is under compression between the platens, and to hold the sheets folded, permitting the thus wrapped bale to be strapped prior to releasing the pressure therefrom.，下面是Apparatus for wrapping bagging and the like about bales of fibers专利的具体信息内容。

权利要求

1. In apparatus for wrapping the side and end portions of sheets about a bale of fibers while under compression between a pair of platens of a press, a. means associated with one of the platens effective to fold the side and end portions of a first sheet about portions of the sides and ends of the bale, comprising a. 1. sheet engaging fingers adjacent the ends of the bale, a. 2. other sheet engaging fingers located adjacent the sides of the bale, a. 3. said sheet of material being disposed to be folded over said fingers located adjacent the ends of the bale prior to wrapping the bale, a. 4. means to move all of said fingers from a position inwardly of the top of said platen to a position alongside the respective ends and sides of the bale, whereby the material is wrapped about and held against the adjacent portions of the sides and ends of the bale, and b. means associated with the other platen effective to fold the side and end portions of a second sheet about portions of the sides and ends of the bale.

2. Apparatus as defined in claim 1 in which all of said sheet engaging fingers are retractable from said sheet folding position to a position to and within the vertically projected confines of the said platen, whereby the platen may be ''''dressed'''' with the sheet and then withdrawn into a fiber charging box or the like.

2. means operable when the arms are in generally horizontal position to attach the end corner portions of a sheet of wrapping material lying between said platen and the top of the bale to the outer ends of the arms, whereby the vertical and offset pivotal movement of the arm wraps the end portions of the sheet about the ends of the bale and around portions of the side of the bale adjacent its ends.

3. Apparatus as defined in claim 1 in which said means associated with one of the platens effective to fold the side and end portions of said first named sheet about portions of the sides and ends of the bale comprises arms pivoted adjacent the sides of the platen near their inner ends and extending outwardly and downwardly for the outer ends thereof to lie alongside the sides of the platen, generally vertically disposed sheet engaging and folding arms pivotally mounted adjacent the outer ends of said arms, means to move the outer ends of said arms upwardly substantially in unison, whereby said pivoted arms move upwardly to press the sheet previously draped thereover about the ends of the bale, and means carried by the pivoted arms to engage and fold along the sides of the bale portions of the sheet joined to the vertically moved, bale end sections thereof.

4. Apparatus as defined in claim 3 in which there are outstanding sheet engaging fingers carried by the pivoted arms, means to rotate the pivoted arms in directions to cause such sheet engaging fingers carried thereby to engage and fold said sheet portions against the sides of the bale, and other generally vertically disposed sheet engaging fingers carried by the pivoted arms and located intermediate the ends thereof and disposed upon vertical movement of the pivoted arms to engage the side portions of the sheet after the same are folded vertically, thereby to hold the side portions in folded position, awaiting downfolding of the sheet associated with the other of said platens.

5. In apparatus for wrapping the side and end portions of sheets about a bale of fibers while under compression between a pair of platens of a press, a. means associated with one of the platens effective to fold the side and end portions of a first sheet about portions of the sides and ends of the bale, and b. means associated with the other platen effective to fold the side and end portions of a second sheet about portions of the sides and ends of the bale comprising

6. Apparatus as defined in claim 5 in which there are pairs of sheet engaging fingers associated with said other platen adjacent the corners thereof and disposed, upon vertical movement of said pairs of arms, to engage the sheet being folded, adjacent the fold lines at the corners thereof, aiding in folding the sheet alongside the sides of the bale in response to vertical and pivotal movement of said pairs of arms.
