Abstract
Abstract A tufted pile loop fabric comprising successive transverse lines of loops of yarn having a bulk equivalent to wool yarn of 16 to 23 yards per ounce and about 35 to 47 pile loops per square inch with certain loops in each transverse line more closely spaced than others to form spaced tightly packed areas which are offset in successive stitches to eliminate the appearance of lines in the fabric.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
A tufted loop pile fabric comprising a fabric backing layer and pile loops tufted therein, said pile loops being composed of a yarn equivalent in bulk to a wool yarn of 16 to 23 yards per ounce, being arranged in a series of transverse lines and longitudinal rows and having a loop density sufficient to form tightly packed pile loops, said loops being arranged in groups, which are more widely spaced than the loops in each group, the loops of each group extending through separate needle holes in the backing fabric and being so closely spaced that they are disPlaced from their normal positions in said backing fabric by their mutual contact to provide a patternless effect.
Claim 2
Dependent Claim
117 words
A tufted loop pile fabric comprising a fabric backing layer and pile loops tufted therein, said pile loops being composed of a yarn equivalent in bulk to a wool yarn of 16 to 23 yards per ounce, being arranged in a series of transverse lines and longitudinal rows and having a loop density sufficient to form tightly packed pile loops, said loops being arranged in groups, which are more widely spaced than the loops in each group, the loops of each group extending through separate needle holes in the backing fabric and being so closely spaced that they are disPlaced from their normal positions in said backing fabric by their mutual contact to provide a patternless effect.
Claim 3
Dependent Claim
61 words
A tufted loop pile fabric as set forth in claim 1 wherein the loops of each group are formed by the same pile yarn in successive stitches, the stitches being so closely spaced that the loops are in mutual contact, successive groups of loops in the longitudinal direction being offset transversely to avoid the formation of apparent lines in the fabric.
Claim 4
Dependent Claim
27 words
A tufted loop pile fabric as set forth in claim 1 wherein the loops of each group lie in the same transverse line across said backing fabric.
Claim 5
Dependent Claim
17 words
A fabric as set forth in claim 3 in which the groups are offset in successive stitches.
Claim 6
Dependent Claim
21 words
A loop pile fabric as set forth in claim 3 wherein the group are separated by at least one individual loop.
Claim 7
Dependent Claim
18 words
A loop pile fabric as set forth in claim 3 wherein the loops of each group are offset.
