Abstract
Abstract Wrapping sheets are propelled across the opposed platens of a baling press. After compression, the press box is removed from the bale, and thereafter wrapper folding members move along the bale walls to fold the freed edge portions of the wrapping sheets thereagainst. Finally, while the folds are held, securing bands are applied about the bale which is then released and removed.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
111 words
The combination with a baling press having charge compression means including opposed platens, of automatic bale wrapping means comprising powered mechanism for applying wrapping material across at least one of said platens prior to compression of a charge thereagainst, a press box normally positioned between and normally spaced from said platens to accommodate said mechanism, wrapper folding means movable along opposite faces of the compressed bale for applying said material to at least one of the faces of the bale, means for applying bale-securing elements about said applied wrapping material, and means for separating said box at least in part, from the bale to provide clearance for said wrapper folding means.
Claim 2
Dependent Claim
111 words
The combination with a baling press having charge compression means including opposed platens, of automatic bale wrapping means comprising powered mechanism for applying wrapping material across at least one of said platens prior to compression of a charge thereagainst, a press box normally positioned between and normally spaced from said platens to accommodate said mechanism, wrapper folding means movable along opposite faces of the compressed bale for applying said material to at least one of the faces of the bale, means for applying bale-securing elements about said applied wrapping material, and means for separating said box at least in part, from the bale to provide clearance for said wrapper folding means.
Claim 3
Dependent Claim
33 words
The combination described in claim 1 including mechanism for applying individual sheets of wrapping material to both of said platens and wrapper folding members movable oppositely along a plurality of the bale faces.
Claim 4
Dependent Claim
25 words
The combination described in claim 1 in which said box is axially slidable relative to said platens for clearing a bale compressed between said platens.
Claim 5
Dependent Claim
38 words
The combination described in claim 3 in which said wrapper folding members are at least in part mounted on said box for actuation along faces of the bale when said box has been shifted clear of the bale.
Claim 6
Dependent Claim
26 words
The combination described in claim 4 further including framing structure adjacent one of said platens, others of said wrapper folding members being mounted on said structure.
Claim 7
Dependent Claim
45 words
The combination described in claim 3 in which said press is of the double box type including a center support and a rigid frame pivotally mounted thereon, there being a pair of said boxes slidably mounted on said frame on opposite sides of said support.
Claim 8
Dependent Claim
79 words
The combination with a baling press having a press box and ram platens at the ends of said box, of a pair of tables between said box and platens and each having apertures registering with said box and platens, supplies of wrapping material adjacent said apertures, and means for feeding sheets of said material along said tables and across said apertures and for severing said sheets to provide bale wrappers between said platens and a charge in said box.
Claim 9
Dependent Claim
79 words
The combination with a baling press having a press box and ram platens at the ends of said box, of a pair of tables between said box and platens and each having apertures registering with said box and platens, supplies of wrapping material adjacent said apertures, and means for feeding sheets of said material along said tables and across said apertures and for severing said sheets to provide bale wrappers between said platens and a charge in said box.
Claim 10
Dependent Claim
43 words
The combination described in claim 7 further including means for sliding said box endwise relative to said platens, for clearing opposed faces of a bale compressed against said platens, and wrapper folding members movable along said faces for folding said severed sheet thereagainst.
Claim 11
Dependent Claim
22 words
The combination described in claim 8 in which said wrapper folding members are at least in part movably mounted on said box.
Claim 12
Dependent Claim
98 words
The combination with a baling press having a frame, opposed platens, a press box normally between said platens, and automatic strapping mechanism movable along said frame for applying banding transversely about a bale compressed between said platens, of means to apply sheets of wrapping material across the faces of said platens and extending peripherally therebeyond, means to separate said box at least in part from a bale compressed between said platens to expose faces of the bale, and folding members movably mounted on the press and actuable along exposed faces of the bale for folding said material thereacross.
Claim 13
Dependent Claim
98 words
The combination with a baling press having a frame, opposed platens, a press box normally between said platens, and automatic strapping mechanism movable along said frame for applying banding transversely about a bale compressed between said platens, of means to apply sheets of wrapping material across the faces of said platens and extending peripherally therebeyond, means to separate said box at least in part from a bale compressed between said platens to expose faces of the bale, and folding members movably mounted on the press and actuable along exposed faces of the bale for folding said material thereacross.
Claim 14
Dependent Claim
56 words
The combination described in claim 10 further including folding members mounted on said strapping mechanism for movements at 90° to the directions of movement of said previously mentioned folding members and oppositely along opposed end faces of the compressed bale for folding the corner flaps of said material between previously folded side and end portions thereof.
Claim 15
Dependent Claim
35 words
The combination described in claim 10 in which said box is slidable endwise to clear the faces of the compressed bale and said first-mentioned folding members are mounted at least in part on said box.
Claim 16
Dependent Claim
54 words
The combination described in claim 10 further including banding head and band track means normally spaced from the bale and movable toward the bale to direct banding endwise around the bale and having a part engagable with the bale to hold the end folds of the wrapping material during the application of the banding.
Claim 17
Dependent Claim
34 words
The combination described in claim 12 further including structure at the top end of said box for supporting the extending edges of the lower of said wrapping sheets to control wrinkling thereof during folding.
Claim 18
Dependent Claim
52 words
The combination described in claim 11 further including foot elements spaced apart slightly less than the width of the bale and movable to press opposed extending portions of said lower wrapper sheet against said box top structure to resist uncontrolled wrinkling of said opposed portions during folding of the intervening extended portions.
Claim 19
Dependent Claim
62 words
A baling press having a frame, a press box movable in said frame, a control device carried by said box, energizing means for said device mounted adjacent said box, flexible conduit means connecting said energizing means and said device, and guide elements directing the travel of said conduit means to prevent interference between said conduit means and other parts of the press.
Claim 20
Dependent Claim
62 words
A baling press having a frame, a press box movable in said frame, a control device carried by said box, energizing means for said device mounted adjacent said box, flexible conduit means connecting said energizing means and said device, and guide elements directing the travel of said conduit means to prevent interference between said conduit means and other parts of the press.
Claim 21
Dependent Claim
22 words
