Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
117 words
A laminated non-woven fabric having particular utility as a bedding blanket, comprised by: a core of flexible cellular sheet material; spaced rows of reinforcing elements incorporated into the core and dimensionally stabilizing the core against stretching in a first direction; first and second facings on opposite sides of said core, one of said facings being of fibrous sheet material; the fibers of said fibrous sheet material facing being partially embedded within the other facing sheet at the opposite side of the core; the fibers of said one said fibrous sheet material facing being oriented in a direction transverse to said rows of reinforcing elements, and dimensionally stabilizing the fabric in a direction transverse to said first direction.
Claim 2
Dependent Claim
117 words
A laminated non-woven fabric having particular utility as a bedding blanket, comprised by: a core of flexible cellular sheet material; spaced rows of reinforcing elements incorporated into the core and dimensionally stabilizing the core against stretching in a first direction; first and second facings on opposite sides of said core, one of said facings being of fibrous sheet material; the fibers of said fibrous sheet material facing being partially embedded within the other facing sheet at the opposite side of the core; the fibers of said one said fibrous sheet material facing being oriented in a direction transverse to said rows of reinforcing elements, and dimensionally stabilizing the fabric in a direction transverse to said first direction.
Claim 3
Dependent Claim
16 words
The fabric of claim 1, in which said core is a sheet of cellular plastics material.
Claim 4
Dependent Claim
17 words
The fabric of claim 1, in which said core is a sheet of closed-cell cellular plastics material.
Claim 5
Dependent Claim
17 words
The fabric of claim 1, in which said rows of reinforcing elements extend longitudinally of the core.
Claim 6
Dependent Claim
19 words
The fabric of claim 1, in which said reinforcing elements extend longitudinally of the core is substantially straight lines.
Claim 7
Dependent Claim
24 words
The fabric of claim 1, in which said reinforcing elements are filaments incorporated into the core in rows which are spaced from each other.
Claim 8
Dependent Claim
24 words
The fabric of claim 1, in which said reinforcing elements are spaced rows of filaments bonded to at least one face of said core.
Claim 9
Dependent Claim
19 words
The fabric of claim 1, in which said reinforcing elements are spaced rows of filaments stitched through said core.
Claim 10
Dependent Claim
20 words
The fabric of claim 1, in which said facing of fibrous sheet material is a sheet of needled fiber batting.
Claim 11
Dependent Claim
21 words
The fabric of claim 1, in which each of said first and second facings is a sheet of needled fiber batting.
Claim 12
Dependent Claim
38 words
The fabric of claim 1, in which each of said first and second facings is a sheet of needled fiber batting, the fibers of each said facing being partially embedded within the fibers of the opposite facing sheet.
Claim 13
Dependent Claim
33 words
The fabric of claim 9, in which a dominant number of the fibers in said fibrous sheet material facing are oriented transversely of said first direction at acute angles relatively to each other.
Claim 14
Dependent Claim
33 words
The fabric of claim 11, in which each said first and second facing sheet includes a dominant number of fibers oriented transversely of said first direction at acute angles relatively to each other.
Claim 15
Independent Claim
83 words
A method of manufacturing a laminated non-woven fabric having particular utility as a bedding blanket, comprising the steps of: incorporating spaced rows of reinforcing elements into a core of flexible cellular sheet material; orienting a facing of fibrous batting material on at least one side of said core with the fibers of the batting extending transversely of said rows of reinforcing elements; and, embedding selected groups of fibers of said facing sheet within a facing sheet at the opposite side of said core.
Claim 16
Independent Claim
83 words
A method of manufacturing a laminated non-woven fabric having particular utility as a bedding blanket, comprising the steps of: incorporating spaced rows of reinforcing elements into a core of flexible cellular sheet material; orienting a facing of fibrous batting material on at least one side of said core with the fibers of the batting extending transversely of said rows of reinforcing elements; and, embedding selected groups of fibers of said facing sheet within a facing sheet at the opposite side of said core.
Claim 17
Dependent Claim
31 words
The method of claim 14, including the steps of incorporating said spaced rows of reinforcing elements into said core by stitching said flexible cellular sheet material with spaced rows of filaments.
Claim 18
Dependent Claim
12 words
The method of claim 15, in which said stitching is chain stitching.
Claim 19
Dependent Claim
55 words
The method of claim 14, including the steps of orienting facings of fibrous batting material on both sides of said core, feeding the laminate thus formed to a needle loom, and needling fibers from each of said facings through said core and partially into the opposite said facing without extending beyond the respective outer facing.
Claim 20
Dependent Claim
50 words
The method of claim 19, including the steps of subsequently tentering the formed needled laminate in a direction transverse to said rows of reinforcing elements, to further orient the fibers in said facings and dimensionally stabilize said formed needled laminate against stretching in a direction transverse to said reinforcing elements.
