Claim 2
Dependent Claim
98 words
Base fabric with bilateral piles, comprising a base fabric; and first and second thread means knitted from opposite sides of said base fabric to form first wales and first courses on one side, and second wales and second courses on the other side of said base fabric, respectively, said first and second thread means forming, respectively, two groups of pile loop portions, one group extending between adjacent first wales and successive first courses on said one side, and the other group extending between adjacent second wales and successive second courses on said other side of said base fabric.
Claim 3
Dependent Claim
36 words
Base fabric with bilateral piles as claimed in claim 1 wherein said first and second courses are spaced the same distance, respectively; and wherein said first courses are staggered to said second courses half said distance.
Claim 4
Dependent Claim
139 words
Base fabric with bilateral piles, comprising a base fabric; and first and second thread means knitted from opposite sides of said base fabric to form first wales and first courses on one side, and second wales and second courses on the other side of said base fabric, respectivEly, said first and second thread means forming, respectively, two groups of pile loop portions, one group extending between adjacent first wales and successive first courses on said one side, and the other group extending between adjacent second wales and successive second courses on said other side of said base fabric, said one group of pile loop portions being the back loop portions of loops of said second wales and courses, and said other group of pile loop portions being the back loop portions of loops of said first wales and courses.
Claim 5
Dependent Claim
139 words
Base fabric with bilateral piles, comprising a base fabric; and first and second thread means knitted from opposite sides of said base fabric to form first wales and first courses on one side, and second wales and second courses on the other side of said base fabric, respectivEly, said first and second thread means forming, respectively, two groups of pile loop portions, one group extending between adjacent first wales and successive first courses on said one side, and the other group extending between adjacent second wales and successive second courses on said other side of said base fabric, said one group of pile loop portions being the back loop portions of loops of said second wales and courses, and said other group of pile loop portions being the back loop portions of loops of said first wales and courses.
Claim 6
Dependent Claim
17 words
Base fabric with bilateral piles as claimed in claim 3 wherein said first and second wales register.
Claim 7
Dependent Claim
201 words
Base fabric with bilateral piles as claimed in claim 3 wherein said first and second thread means include sets of first and second threads, respectively; wherein said first wales and first courses consist of first loops having a first front loop portion on said one side, and a first back loop portion on said other side of said base fabric; wherein first loops formed of the same first thread are located in successive first courses in adjacent first wales whereby said first back loop portions extend between successive first courses and adjacent first wales on said other side of said base fabric; wherein said second wales and second courses consist of second loops having a second front loop portion on said other side, and a second back loop portion of said one side of said base fabric; and wherein second loops formed of the same second thread are located in successive second courses in adjacent second wales whereby said second back loop portions extend between successive second wales and adjacent second courses on said one side of said fabric so that said second and first back loop portions form, respectively, said one group and said other group of pile loop portions.
Claim 8
Dependent Claim
44 words
Base fabric with bilateral piles as claimed in claim 5 wherein said first and second wales register; wherein said first and second courses are spaced the same distance, respectively; and wherein said first courses are staggered to said second courses, respectively, half said distance.
Claim 9
Dependent Claim
206 words
Base fabric with bilateral piles, comprising a base fabric; and first and second thread means knitted from opposite sides of said base fabric to form first wales and first courses on the other side of said base fabric, respectively, said first thread means including a set of first binding threads forming said first wales of first binding chain loops, and a set of first pile threads, each first pile thread being anchored by first binding chain loops of said first binding threads located in adjacent first wales and successive first courses, and said second thread means including a set of second binding threads forming said second wales of second binding chain loops, and a set of second pile threads, each second pile thread being anchored by said second binding chain loops of said second binding threads located in adjacent second wales and successive second courses, said first binding chain loops forming one group of pile loop portions and said second binding loops forming an other group of pile loop portions, said one group extending between adjacent first wales and successive first courses of said one side, and said other group extending between adjacent second wales and successive second courses on said other side of said fabric.
Claim 10
Dependent Claim
206 words
Base fabric with bilateral piles, comprising a base fabric; and first and second thread means knitted from opposite sides of said base fabric to form first wales and first courses on the other side of said base fabric, respectively, said first thread means including a set of first binding threads forming said first wales of first binding chain loops, and a set of first pile threads, each first pile thread being anchored by first binding chain loops of said first binding threads located in adjacent first wales and successive first courses, and said second thread means including a set of second binding threads forming said second wales of second binding chain loops, and a set of second pile threads, each second pile thread being anchored by said second binding chain loops of said second binding threads located in adjacent second wales and successive second courses, said first binding chain loops forming one group of pile loop portions and said second binding loops forming an other group of pile loop portions, said one group extending between adjacent first wales and successive first courses of said one side, and said other group extending between adjacent second wales and successive second courses on said other side of said fabric.
