Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
102 words
The method of drawing and blending textile fiber and metal filaments while maintaining contact with each other comprising, feeding at least onE bundle of fibers of textile material through draw rolls, simultaneously feeding a multifilament metal bundle through said draw rolls, simultaneously feeding a multifilament metal bundle through said draw rolls, guiding said metal bundle relative to said textile bundle to cause the latter continuously to cushion said metal bundle with respect to said draw rolls when passing therethrough while controlling the tension force on said metal filaments, to break limited numbers of said filaments generally continuously during the period of drawing.
Claim 2
Independent Claim
102 words
The method of drawing and blending textile fiber and metal filaments while maintaining contact with each other comprising, feeding at least onE bundle of fibers of textile material through draw rolls, simultaneously feeding a multifilament metal bundle through said draw rolls, simultaneously feeding a multifilament metal bundle through said draw rolls, guiding said metal bundle relative to said textile bundle to cause the latter continuously to cushion said metal bundle with respect to said draw rolls when passing therethrough while controlling the tension force on said metal filaments, to break limited numbers of said filaments generally continuously during the period of drawing.
Claim 3
Independent Claim
102 words
The method of drawing and blending textile fiber and metal filaments while maintaining contact with each other comprising, feeding at least onE bundle of fibers of textile material through draw rolls, simultaneously feeding a multifilament metal bundle through said draw rolls, simultaneously feeding a multifilament metal bundle through said draw rolls, guiding said metal bundle relative to said textile bundle to cause the latter continuously to cushion said metal bundle with respect to said draw rolls when passing therethrough while controlling the tension force on said metal filaments, to break limited numbers of said filaments generally continuously during the period of drawing.
Claim 4
Independent Claim
102 words
The method of drawing and blending textile fiber and metal filaments while maintaining contact with each other comprising, feeding at least onE bundle of fibers of textile material through draw rolls, simultaneously feeding a multifilament metal bundle through said draw rolls, simultaneously feeding a multifilament metal bundle through said draw rolls, guiding said metal bundle relative to said textile bundle to cause the latter continuously to cushion said metal bundle with respect to said draw rolls when passing therethrough while controlling the tension force on said metal filaments, to break limited numbers of said filaments generally continuously during the period of drawing.
Claim 5
Dependent Claim
40 words
The method according to claim 1 wherein said bundle of textile material and bundle of multifilament metal are fed into a plurality of successive sets of draw rolls and said metal bundle is guided into the first set of rolls.
Claim 6
Dependent Claim
48 words
The method according to claim 2 wherein said draw rolls are arranged horizontally, and a plurality of textile bundles and metal bundles are fed to said rolls, said textile bundles being in side by side relationship and each of said metal bundles overlying one of said textile bundles.
Claim 7
Dependent Claim
24 words
The method according to claim 1 wherein said textile bundles and metal bundles have similar surface friction characteristics with respect to said draw rolls.
Claim 8
Dependent Claim
19 words
The method according to claim 4 wherein said textile bundle is cotton and said metal bundle is stainless steel.
Claim 9
Dependent Claim
22 words
The method according to claim 5 wherein said stainless steel is made of metal filaments in the 4 to 12 micron range.
Claim 10
Dependent Claim
23 words
The method according to claim 1 wherein the textile bundles after drawing are passed through a roving and spinning steps to create yarn.
Claim 11
Dependent Claim
167 words
Apparatus for simultaneous drawing of bundles of textile fiber and metal filaments comprising, at least one pair of draw rolls, means for feeding at least one bundle of a textile fiber into said draw rolls, means for feeding at least one bundle of metal filaments into draw rolls and means for guiding one of said textile and fiber bundles directly onto the other of said textile and fiber bundles while said textile and fiber bundles are passing through said first pair of draw rolls so that said metal bundle is not brought directly into contact with both draw rolls of said first pair due to the interposition and cushioning of said fiber bundle between said metal bundle and said draw rolls, said guide means further causing the metal and textile bundles to be brought initially into contact with each other without twisting of said textile bundle or envelopment of said metal bundle by said textile bundle immediately prior to passing through said first pair of draw rolls.
Claim 12
Dependent Claim
167 words
