Abstract
Abstract In order to form a package which includes a length of fabric which at one side edge region is substantially longer than at its other side edge region, the fabric is wound so as to form a wound body of fabric surrounding a given axis, and along the latter axis there is situated a core which has opposed free end regions which respectively have transversely with respect to said axis maximum dimensions one of which is substantially greater than the other. The core end region which is of the greater maximum dimension supports the fabric at its longer side edge region. The core preferably includes tubular and finned core portions, the latter having fins which project from the axis of the core, and the finned core portion extends partly into the tubular core portion.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
206 words
In a method for manufacturing a package which includes a length of fabric having opposed side edge regions one of which is substantially longer than the other which is wound around a core having first and second telescoping portions aligned along their longitudinal axes and which are axially shiftable with respect to each other, said first core portion having a given maximum dimension transverse to its axis and said second core portion having a given maximum dimension transverse to its axis substantially smaller than said maximum dimension of said first core portion, the steps of winding the fabric initially on said first core portion while said second core portion is in a position where it does not extend from said first core portion to form therefrom a body of wound fabric surrounding said first core portion, such that the longer side edge region of said fabric is wound on said first core portion and the shorter side edge region of the fabric extends axially beyond said first core portion, and then axially shifting said second core portion with respect to said first core portion to a location where said maximum dimension of said second core portion is situated at the shorter edge region of the fabric.
Claim 2
Dependent Claim
206 words
In a method for manufacturing a package which includes a length of fabric having opposed side edge regions one of which is substantially longer than the other which is wound around a core having first and second telescoping portions aligned along their longitudinal axes and which are axially shiftable with respect to each other, said first core portion having a given maximum dimension transverse to its axis and said second core portion having a given maximum dimension transverse to its axis substantially smaller than said maximum dimension of said first core portion, the steps of winding the fabric initially on said first core portion while said second core portion is in a position where it does not extend from said first core portion to form therefrom a body of wound fabric surrounding said first core portion, such that the longer side edge region of said fabric is wound on said first core portion and the shorter side edge region of the fabric extends axially beyond said first core portion, and then axially shifting said second core portion with respect to said first core portion to a location where said maximum dimension of said second core portion is situated at the shorter edge region of the fabric.
Claim 3
Dependent Claim
29 words
In a method as recited in claim 1 and wherein the step of winding the fabric onto said first core portion takes place while said axis is substantially horizontal.
Claim 4
Dependent Claim
159 words
A core for supporting a wound body of fabric which has opposed side edge regions one of which is substantially longer than the other, comprising an elongated tubular core portion having a given central axis and an elongated finned core portion also having an elongated central axis and including a plurality of fins projecting from the latter axis, said finned core portion extending in part into said tubular core portion while engaging and being supported by said tubular core portion, with said central axes of both core portions coinciding, and with each core portion having a free end region distant from the other core portion, said free end regions respectively having transverse to said coinciding central axes maximum dimensions one of which is substantially greater than the other, so that the fabric can be wound onto said core portions with the longer side edge region of the fabric situated at that end region which has the greater maximum dimension.
Claim 5
Dependent Claim
159 words
A core for supporting a wound body of fabric which has opposed side edge regions one of which is substantially longer than the other, comprising an elongated tubular core portion having a given central axis and an elongated finned core portion also having an elongated central axis and including a plurality of fins projecting from the latter axis, said finned core portion extending in part into said tubular core portion while engaging and being supported by said tubular core portion, with said central axes of both core portions coinciding, and with each core portion having a free end region distant from the other core portion, said free end regions respectively having transverse to said coinciding central axes maximum dimensions one of which is substantially greater than the other, so that the fabric can be wound onto said core portions with the longer side edge region of the fabric situated at that end region which has the greater maximum dimension.
Claim 6
Dependent Claim
23 words
The combination of claim 3 and wherein the fins of said finned core portion are at least in part of a tapered configuration.
Claim 7
Dependent Claim
137 words
The combination of claim 4 and wherein said finned core portion includes a pair of sheet members having opposed ends one of which is narrower than the other, and said sheet members being axially slotted along part of their length with the slot of one of said members extending from the narrow end thereof while the slot of the other said members extends from the wider end thereof, and said sheet members being interlocked at the slotted portions thereof for providing for said finned portion of said core fins which project from said central axis thereof, so that said finned portion can be folded to a flat condition when not in use while capable of being turned at said sheet members thereof to a position of use where said sheet members are substantially normal to each other.
Claim 8
Dependent Claim
54 words
