Abstract
Abstract A knit fabric is provided in which a woven structure is simulated by feeding spaced warp ends while laying filling ends at opposite sides of the warp ends and causing weft stitch courses to be knit so that needle loops thereof form wales running in the space between the warp ends and passing outside of filling ends at both sides of the warp ends while intervening sinker loop portions pass to one side of the warp ends. Such fabric can be formed on any type of weft knitting means that has been adapted properly.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
97 words
In the formation of knit fabric simulating a woven structure which involves the steps of feeding spaced warp ends to weft knitting means while laying filling ends at opposite sides of the fed warp, the improvement which comprises causing needle loops of weft knit courses to form wales at the spaces between the warp ends and to execute a shedding motion in relation to said warp in the course of such wale formation so that filling ends are disposed between the needle loops and the warp at both faces of the resulting fabric as it is formed.
Claim 2
Dependent Claim
97 words
In the formation of knit fabric simulating a woven structure which involves the steps of feeding spaced warp ends to weft knitting means while laying filling ends at opposite sides of the fed warp, the improvement which comprises causing needle loops of weft knit courses to form wales at the spaces between the warp ends and to execute a shedding motion in relation to said warp in the course of such wale formation so that filling ends are disposed between the needle loops and the warp at both faces of the resulting fabric as it is formed.
Claim 3
Dependent Claim
118 words
In weft knitting apparatus for forming knit fabric simulating a woven structure and having means for feeding spaced warp ends to a knitting station while laying filling ends at opposite sides of the fed warp, the improvement which comprises needle means operable at said knitting station between said spaced warp ends to draw knitting yarn into needle loops forming wales thereat, and cam means for causing said needle means to operate in the course of such wale formation so that each drawn needle loop executes a shedding motion in relation to said warp ends sufficient to receive a filling end between the needle loops and the warp at both faces of the resulting fabric as it is knit.
Claim 4
Dependent Claim
118 words
In weft knitting apparatus for forming knit fabric simulating a woven structure and having means for feeding spaced warp ends to a knitting station while laying filling ends at opposite sides of the fed warp, the improvement which comprises needle means operable at said knitting station between said spaced warp ends to draw knitting yarn into needle loops forming wales thereat, and cam means for causing said needle means to operate in the course of such wale formation so that each drawn needle loop executes a shedding motion in relation to said warp ends sufficient to receive a filling end between the needle loops and the warp at both faces of the resulting fabric as it is knit.
Claim 5
Dependent Claim
25 words
In weft knitting apparatus the improvement defined in claim 2 in which the needle means comprises double-hooked needles having a latch at only one end.
Claim 6
Dependent Claim
23 words
In weft knitting apparatus the improvement defined in claim 2 in which the needle means comprises double-hooked needles having latches at both ends.
