Abstract
Abstract Looped tufts of yarn are drawn through proximate openings in a foundation fabric from opposite sides of the fabric and are intertwined in pairs to form square knots that secure opposed tufts of yarn to each other and to the fabric strands separating the proximate openings. The free ends of each pair of knotted yarn tufts extend in opposite directions from opposite sides of the foundation fabric. Such knotted yarn tufts cover both sides of the foundation fabric and form piles on both sides thereof. Different colored yarn tufts may be used and may be arranged to form predetermined decorative patterns on both sides of the article. The patterns on opposite sides of the article can be the same or they can be entirely different.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
164 words
A method of making reversible hooked articles on a base comprising a foundation fabric having crossed strands with openings between adjacent crossed strands, comprising the steps of: a. pulling a first looped tuft of yarn part way through one of said openings from one side of said foundation fabric; b. pulling a second looped tuft of yarn part way through a proximate opening from the other side of said foundation fabric, the second yarn tuft passing through the loop of the first yarn tuft; c. pulling the free ends of one yarn tuft through the loop of the other yarn tuft to form a square knot securing said yarn tufts to each other and to the foundation fabric strands separating said proximate openings; d. tightening said square knot; and e. repeating steps (a) through (d) over successive proximate openings in said foundation fabric to cover both surfaces of said fabric with symetrically disposed tufts to form piles on both sides of said foundation fabric.
Claim 2
Independent Claim
164 words
A method of making reversible hooked articles on a base comprising a foundation fabric having crossed strands with openings between adjacent crossed strands, comprising the steps of: a. pulling a first looped tuft of yarn part way through one of said openings from one side of said foundation fabric; b. pulling a second looped tuft of yarn part way through a proximate opening from the other side of said foundation fabric, the second yarn tuft passing through the loop of the first yarn tuft; c. pulling the free ends of one yarn tuft through the loop of the other yarn tuft to form a square knot securing said yarn tufts to each other and to the foundation fabric strands separating said proximate openings; d. tightening said square knot; and e. repeating steps (a) through (d) over successive proximate openings in said foundation fabric to cover both surfaces of said fabric with symetrically disposed tufts to form piles on both sides of said foundation fabric.
Claim 3
Dependent Claim
48 words
The method of claim 1 wherein looped tufts of different colored yarn are utilized to form said reversible hooked article, the different colored tufts being spatially arranged on both surfaces of said foundation fabric to form predetermined colored patterns on both surfaces of said reversible tufted sheet material.
Claim 4
Dependent Claim
28 words
The method of claim 2 wherein the colored pattern on one surface of said reversible hooked article is different from the colored pattern on the other surface thereof.
Claim 5
Dependent Claim
35 words
The method of claim 2 wherein guide lines are marked on at least one surface of said foundation fabric to serve as a guide for the spatial arrangement of said tufts of different colored yarn.
Claim 6
Dependent Claim
43 words
The method of claim 4 wherein guide lines are marked on both surfaces of said foundation fabric and wherein the pattern of guide lines on one surface of said foundation fabric differs from the pattern of guide lines on the other surface thereof.
Claim 7
Dependent Claim
49 words
The method of claim 2 wherein each tuft of one color yarn on one side of the article is knotted to a tuft of another color yarn on the other side of the article to form patterns on the opposite surfaces of said article which are identical in form.
Claim 8
Dependent Claim
50 words
The method of claim 1 wherein one looped tuft of yarn is manually pulled part way through said opening by a hook held in one hand and the other looped tuft of yarn is manually pulled part way through said proximate opening by a hook held in the other hand.
Claim 9
Dependent Claim
36 words
The method of claim 7 wherein the free ends of one looped tuft are manually pulled through the loop of the other looped tuft by a hook held in one hand and extended through said loop.
Claim 10
Dependent Claim
28 words
The method of claim 1 and further comprising the step of simultaneously manually tugging on the free ends of said two looped tufts to tighten said square knot.
Claim 11
Dependent Claim
15 words
The method of claim 1 wherein said proximate opening is adjacent to the first-mentioned opening.
Claim 12
Independent Claim
140 words
A method of making reversible hooked articles on a mesh base comprising the steps of: a. mounting the mesh base on a frame; b. positioning the frame in edge relation to an operator so that the operator faces the edge of the frame with one hand at each side of the mesh base; c. disposing hooks in each hand of the operator; d. using said hooks sequentially to draw looped tufts of yarn from opposite sides of the mesh base through proximate openings in said mesh base; e. shifting said hooks in the operator's hand between a projecting hooking position and a retracted palmed position in which the operator's thumb and forefinger are free to manipulate the yarn, without laying down the hooks; and f. knotting the looped ends of the tufts together about a strand of the mesh base.
Claim 13
Independent Claim
140 words
A method of making reversible hooked articles on a mesh base comprising the steps of: a. mounting the mesh base on a frame; b. positioning the frame in edge relation to an operator so that the operator faces the edge of the frame with one hand at each side of the mesh base; c. disposing hooks in each hand of the operator; d. using said hooks sequentially to draw looped tufts of yarn from opposite sides of the mesh base through proximate openings in said mesh base; e. shifting said hooks in the operator's hand between a projecting hooking position and a retracted palmed position in which the operator's thumb and forefinger are free to manipulate the yarn, without laying down the hooks; and f. knotting the looped ends of the tufts together about a strand of the mesh base.
Claim 14
Dependent Claim
21 words
The method of claim 11 in which step (d) includes drawing one tuft through the looped end of the other tuft.
Claim 15
Dependent Claim
25 words
The method of claim 12 in which step (f) includes drawing the free ends of one tuft through the looped end of the other tuft.
