Abstract
Abstract A circular hosiery knitting machine in which the toe is closed by twisting on the machine. The stocking is knitted in the normal direction, starting with an inturned double welt in the usual manner. Going into the toe, heavier yarns are introduced with circular knitting using two feeds, and loops are transferred onto the dial jack and held during subsequent knitting of the toe, with the needles alternately knitting and welting during knitting of the toe portion. At the completion of the toe knitting, the dial is allowed to rotate one revolution with respect to the body to introduce a twist between the dial loops and the needles. After the twisting has been done, the loops are transferred onto the needles and knitted in, after which additional fabric courses defining a tab are knitted with an anti-ravel structure, and the stocking is pressed off.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
192 words
A stocking having a foot with a closed toe, said toe comprising a fold having two circularly knit tubular plies of fabric continuous with each other across the fold and having coursewise extending joined terminal portions with the fabric running continuously from the terminal portion of one ply across said fold to the terminal portion of the other ply, said plies being constricted radially together at said fold substantially to fill and close the tubular opening defined by said tubular plies, said terminal portions being joined by interlocked courses of said terminal portions, one of said plies continuing from said interlocked courses in the directiOn away from said fold to form the foot of the stocking, each course in said toe having a lesser number of loops than in the courses of said foot and said toe having the same number of wales as there are in said foot wherein at least two of every four contiguous courses of said toe include one course consisting of loops in alternate wales extending over at least two courses and a second course consisting of loops in intervening wales extending over at least two courses.
Claim 2
Dependent Claim

A stocking having a foot with a closed toe, said toe comprising a fold having two circularly knit tubular plies of fabric continuous with each other across the fold and having coursewise extending joined terminal portions with the fabric running continuously from the terminal portion of one ply across said fold to the terminal portion of the other ply, said plies being constricted radially together at said fold substantially to fill and close the tubular opening defined by said tubular plies, said terminal portions being joined by interlocked courses of said terminal portions, one of said plies continuing from said interlocked courses in the directiOn away from said fold to form the foot of the stocking, each course in said toe having a lesser number of loops than in the courses of said foot and said toe having the same number of wales as there are in said foot wherein at least two of every four contiguous courses of said toe include one course consisting of loops in alternate wales extending over at least two courses and a second course consisting of loops in intervening wales extending over at least two courses.
Claim 3
Dependent Claim
42 words
A stocking as set forth in claim 1 wherein said loops in said one and said second courses extend over three courses and each of said one and said second courses alternates with an intervening course having loops extending over one course.
Claim 4
Dependent Claim
180 words
A stocking having a foot with a closed toe, said toe comprising a fold having two circularly knit tubular plies of fabric continuous with each other across the fold and having coursewise extending joined terminal portions with the fabric running continuously from the terminal portion of one ply across said fold to the terminal portion of the other ply, said plies being constricted radially together at said fold substantially to fill and close the tubular opening defined by said tubular plies, said terminal portions being joined by interlocked courses of said terminal portions, one of said plies continuing from said interlocked courses in the direction away from said fold to form the foot of the stocking, each course in said toe having a lesser number of loops than in the courses of said foot and said toe having the same number of wales as there are wales in said foot, wherein said toe consists of alternate courses consisting of loops in alternate wales extending over two courses and intervening courses consisting of loops in intervening wales extending over two courses.
Claim 5
Dependent Claim
180 words
A stocking having a foot with a closed toe, said toe comprising a fold having two circularly knit tubular plies of fabric continuous with each other across the fold and having coursewise extending joined terminal portions with the fabric running continuously from the terminal portion of one ply across said fold to the terminal portion of the other ply, said plies being constricted radially together at said fold substantially to fill and close the tubular opening defined by said tubular plies, said terminal portions being joined by interlocked courses of said terminal portions, one of said plies continuing from said interlocked courses in the direction away from said fold to form the foot of the stocking, each course in said toe having a lesser number of loops than in the courses of said foot and said toe having the same number of wales as there are wales in said foot, wherein said toe consists of alternate courses consisting of loops in alternate wales extending over two courses and intervening courses consisting of loops in intervening wales extending over two courses.
