Abstract
Abstract A knit fabric is made to simulate a woven structure by arranging fancy warp stitch chains at spacings between inlaid warp ends so that filling ends laid at one side of the warp ends are knit-in while filling ends laid at the other side remain simply laid-in and are held in place by interaction of the warp ends and warp stitch chains thereat.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
152 words
In the formation of warp knit fabric made to simulate a woven structure which involves the steps of inlaying spaced warp ends at the back side of a needle array while laying filling ends at opposite sides of the warp inlay, the improvement which comprises operating said needle array and feeding knitting ends thereto to form warp stitch chains at the spaces between said warp ends, while causing all filling ends at the side of said warp inlay adjacent the needles of said array to remain at the back of said needles and forcing all filling ends at the other warp inlay side to the front of said needles in timed relation, so that the filling ends forced to the front of said needles are knit-in by said warp stitch chains and the filling ends remaining at the back of said needles are interlaced by said warp ends and warp stitch chains.

Claim 3
Dependent Claim
155 words
In warp knitting apparatus for forming knit fabric having a woven appearance in which means is provided for inlaying spaced warp ends at the back side of a needle array while laying filling ends at opposite sides of the warp inlay and for operating the needles of said array while delivering knitting ends thereto, the improvement which comprises sinker means for holding all filling ends at the side of said warp ends adjacent said needles at the back of said needles while forcing all filling ends at the other warp end side to the front of said needles, and means for operating said sinker means in timed relation so that the filling ends forced to the front of said needles are knit-in by warp stitch chains running at the spaces between said warp ends and the filling ends held at the back of said needles are interlaced by said warp ends and warp stitch chains.
Claim 4
Dependent Claim
155 words
In warp knitting apparatus for forming knit fabric having a woven appearance in which means is provided for inlaying spaced warp ends at the back side of a needle array while laying filling ends at opposite sides of the warp inlay and for operating the needles of said array while delivering knitting ends thereto, the improvement which comprises sinker means for holding all filling ends at the side of said warp ends adjacent said needles at the back of said needles while forcing all filling ends at the other warp end side to the front of said needles, and means for operating said sinker means in timed relation so that the filling ends forced to the front of said needles are knit-in by warp stitch chains running at the spaces between said warp ends and the filling ends held at the back of said needles are interlaced by said warp ends and warp stitch chains.
