Abstract
Abstract A package for endless fabrics, such as forming fabrics used on papermaking machines, the package comprising a pair of inner cores inserted in an elongated endless fabric at its opposite extremities, one of the inner cores being surrounded by an outer core having a longitudinal slot through which the fabric projects, the outer core preferably being of split and hinged construction. The projecting portion of the fabric is wound around the outer core with the other of the inner cores juxtaposed to the rolled fabric and the cores secured together to form the package. The outer core is preferably encapsulated in cushioning material and the edges of the outer core defining the longitudinal slot through which the fabric projects may be enlarged to increase the wrap angle of the fabric, the package acting to prevent creasing of the fabric as it is packaged for shipment and storage.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
180 words
A package for endless papermaking fabrics, said package comprising an elongated endless fabric, a pair of inner cores inserted in said endless fabric at its opposite extremities, an outer core surrounding a first of said inner cores and the portion of the fabric extending around said inner core, said outer core comprising a pair of opposing semi-cylindrical sections, means hingedly connecting said sections together along a mating pair of their side edges, the opposite side edges of the sections being spaced apart to define a longitudinal slot through which the fabric projects, a layer of cushioning material interposed between the inner surface of said outer core and the fabric surrounding the first of said inner cores, the remainder of the fabric extending outwardly beyond said longitudinal slot being wound on said outer core, means extending along at least one edge of said slot acting to increase the angle of wrap of the fabric wound around said outer core, the other of said inner cores being juxtaposed to the rolled fabric, and means securing said cores together to form a package.
Claim 2
Dependent Claim
180 words
A package for endless papermaking fabrics, said package comprising an elongated endless fabric, a pair of inner cores inserted in said endless fabric at its opposite extremities, an outer core surrounding a first of said inner cores and the portion of the fabric extending around said inner core, said outer core comprising a pair of opposing semi-cylindrical sections, means hingedly connecting said sections together along a mating pair of their side edges, the opposite side edges of the sections being spaced apart to define a longitudinal slot through which the fabric projects, a layer of cushioning material interposed between the inner surface of said outer core and the fabric surrounding the first of said inner cores, the remainder of the fabric extending outwardly beyond said longitudinal slot being wound on said outer core, means extending along at least one edge of said slot acting to increase the angle of wrap of the fabric wound around said outer core, the other of said inner cores being juxtaposed to the rolled fabric, and means securing said cores together to form a package.
Claim 3
Dependent Claim
21 words
The package claimed in claim 1 wherein said cushioning material covers both the inner and outer surfaces of said outer core.
Claim 4
Dependent Claim
22 words
The package claimed in claim 2 wherein said cushioning material comprises a packing material having a multiplicity of cushion forming air chambers.
Claim 5
Dependent Claim
32 words
The package claimed in claim 1 wherein the means for increasing the angle of wrap of said fabric comprises an enlargement extending along at least one side edge of said longitudinal slot.
Claim 6
Dependent Claim
32 words
The package claimed in claim 1 wherein the means for increasing the angle of wrap of the fabric comprises cushioning means extending around at least one side edge of said longitudinal slot.
Claim 7
Independent Claim
127 words
A method for packaging endless fabrics which comprises the steps of inserting a pair of inner core members in an elongated endless fabric at its opposite extremities, surrounding a first of said inner cores and the portion of the fabric extending around said first inner core with an outer core having a longitudinal slot therein, including the step of positioning said outer core so that the fabric extends through said longitudinal slot, jointly rotating said first inner core and said outer core to wrap the portion of the fabric extending between said longitudinal slot and the second of said inner cores around said outer core, including the step of juxtaposing said second inner core to the rolled fabric, and securing said cores together to form a package.
Claim 8
Independent Claim
127 words
A method for packaging endless fabrics which comprises the steps of inserting a pair of inner core members in an elongated endless fabric at its opposite extremities, surrounding a first of said inner cores and the portion of the fabric extending around said first inner core with an outer core having a longitudinal slot therein, including the step of positioning said outer core so that the fabric extends through said longitudinal slot, jointly rotating said first inner core and said outer core to wrap the portion of the fabric extending between said longitudinal slot and the second of said inner cores around said outer core, including the step of juxtaposing said second inner core to the rolled fabric, and securing said cores together to form a package.
Claim 9
Dependent Claim
20 words
The method claimed in claim 6 including the step of interposing cushioning material between said fabric and said outer core.
Claim 10
Dependent Claim
21 words
The method claimed in claim 7 wherein said cushioning material covers both the inner and outer surfaces of said outer core.
Claim 11
Dependent Claim
33 words
The method claimed in claim 6 including the step of increasing the angle of wrap of the fabric relative to the outer core by enlarging at least one edge of said longitudinal slot.
Claim 12
Dependent Claim
102 words
The method claimed in claim 6 wherein said outer core comprises an opposing pair of semi-cylindrical sections hingedly connected together along a mating pair of their side edges, said sections being movable from closed to opened position and return, including the steps of opening the tube sections relative to each other, fitting the tube sections around the first inner core and closing the tube sections relative to each other, including the step of positioning the tube sections so that when they are closed, the opposite pair of side edges of said sections will define the longitudinal slot through which the fabric extends.
