Abstract
Abstract A method of producing a textile fabric on a multi-needle stitching machine comprising the steps of feeding at least one film comprised of a synthetic polymer into said stitching machine, actuating said machine, whereby said film is split into a plurality of film elements and simultaneously integrated in the ongoing textile manufacture, and collecting said manufactured textile.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
107 words
A method of producing a textile fabric on a machine of the warp-knitting and multiple needle stitching type, comprising the steps of a. moving fabric elements for the production of said textile fabric, including at least one splittable film comprised of a synthetic polymer and another fabric element, into the machine; b. splitting said film by motion of needles of the machine into a plurality of film elements in form of filaments and substantially simultaneously integrating these filaments with said other fabric element into said textile fabric, at least one of the fabric elements constituting a set of stitching yarns; and c. collecting the integrated textile fabric.
Claim 2
Independent Claim
107 words
A method of producing a textile fabric on a machine of the warp-knitting and multiple needle stitching type, comprising the steps of a. moving fabric elements for the production of said textile fabric, including at least one splittable film comprised of a synthetic polymer and another fabric element, into the machine; b. splitting said film by motion of needles of the machine into a plurality of film elements in form of filaments and substantially simultaneously integrating these filaments with said other fabric element into said textile fabric, at least one of the fabric elements constituting a set of stitching yarns; and c. collecting the integrated textile fabric.
Claim 3
Dependent Claim
26 words
A method as defined in claim 1, wherein said integrating of film elements includes feeding the film elements as warp yarns, lengthwise of said textile fabric.
Claim 4
Dependent Claim
33 words
A method as defined in claim 1, wherein said feeding includes the feeding of several splittable films and mutually superposing the same, said penetrating including motions of said needles through the superposed films.
Claim 5
Dependent Claim
27 words
A method as defined in claim 1, including arranging the film elements split from at least one of said films as pile yarns in said textile fabric.
Claim 6
Dependent Claim
41 words
A method as defined in claim 1, including arranging the film elements split from at least one of said films as weft yarns in said textile fabric, by steps including feeding the respective film in zigzag form transversely into the machine.
Claim 7
Dependent Claim
32 words
A method as defined in claim 1, including stitching by means of said needles the film elements split from at least one of said films as stitching yarns in said textile fabric.
Claim 8
Dependent Claim
50 words
A method as defined in claim 1, including the step of d. feeding at least one of said films into said machine together with a base material, but aT a higher speed than said base material, whereby film elements, split from said film, are concentrated longitudinally on said base material.
Claim 9
Dependent Claim
62 words
A method as defined in claim 7, including the steps of e. forming said concentrated film elements into pile tufts by pile sinking motions performed directly after said splitting of the film; f. drawing the tufts into said base material by knitting in said machine; and g. binding them into chain stitches or wales on the back side of the base material.
Claim 10
Dependent Claim
45 words
A method as defined in claim 7, including the steps of forming said concentrated film elements into pile tufts and fixing the pile tufts to said base material by binding separate stitching yarn into chain stitches or wales while the splitting, forming and binding proceeds.
Claim 11
Dependent Claim
25 words
A method as defined in claim 8, including the step of cutting said pile tufts, on said machine, directly after said forming, sinking and binding.
