Abstract
Abstract This invention relates to a novel method and apparatus for making novel decorative fabrics wherein effect yarns are present on the fabric with the effect yarn being fed in a longitudinally compressed bulked condition imparting an expanded cross-sectional width to the effect yarn and wherein a stitching thread secures the effect yarn in the compressed bulked condition so that there is imparted to the fabric an appearance attendant to an effect yarn much larger than that actually present on the fabric.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
93 words
A method of forming a decorative textile fabric from a substrate and an effect yarn which comprises guiding the effect yarn in a predetermined path of travel to a position adjacent a vertically reciprocating needle of a sewing machine while longitudinally compressing the effect yarn to expand the cross-sectional width of the effect yarn by engaging the effect yarn by the needle and by stitching thread carried by the needle during the downward stroke of the needle and while causing the stitching thread to stitchingly secure the compressed effect yarn to the substrate.
Claim 2
Independent Claim
93 words
A method of forming a decorative textile fabric from a substrate and an effect yarn which comprises guiding the effect yarn in a predetermined path of travel to a position adjacent a vertically reciprocating needle of a sewing machine while longitudinally compressing the effect yarn to expand the cross-sectional width of the effect yarn by engaging the effect yarn by the needle and by stitching thread carried by the needle during the downward stroke of the needle and while causing the stitching thread to stitchingly secure the compressed effect yarn to the substrate.
Claim 3
Dependent Claim
50 words
A method according to claim 1 wherein the substrate is a quilted fabric having lines of stitching therein and wherein the effect yarn is guided onto the substrate so that at least portions of the effect yarn overlie at least portions of the lines of stitching on the quilted fabric.
Claim 4
Dependent Claim
33 words
A method according to claim 1 wherein the effect yarn is guided onto the substrate so that portions of the effect yarn are arranged in overlapping relation and stitchingly secured in overlapping relation.
Claim 5
Dependent Claim
48 words
A method according to claim 1 wherein the sewing machine is a quilting machine and tne substrate is moved manually during the reciprocatory movement of the needle of the quilting machine so as to manually form the desired pattern on the substrate by the movement of the substrate.
Claim 6
Independent Claim
96 words
An apparatus for sewing an effect yarn onto a substrate to form a textile article therefrom comprising a sewing machine having a needle mounted for vertical reciprocation, and a yarn guide apparatus comprising a yarn guide finger, and means mounting said yarn guide finger adjacent said needle and including means biasing said yarn guide finger toward said needle and into a first position in the path of reciprocation of the needle, and said yarn guide finger being movable to a second position outwardly away from said needle in response to the downward stroke of the needle.
Claim 7
Independent Claim
96 words
An apparatus for sewing an effect yarn onto a substrate to form a textile article therefrom comprising a sewing machine having a needle mounted for vertical reciprocation, and a yarn guide apparatus comprising a yarn guide finger, and means mounting said yarn guide finger adjacent said needle and including means biasing said yarn guide finger toward said needle and into a first position in the path of reciprocation of the needle, and said yarn guide finger being movable to a second position outwardly away from said needle in response to the downward stroke of the needle.
Claim 8
Dependent Claim
20 words
An apparatus according to claim 5 wherein said means biasing said yarn guide finger toward said needle comprises spring means.
Claim 9
Dependent Claim
46 words
An apparatus according to claim 5 wherein said yarn guide finger is positioned to extend downwardly at an angle toward said needle of the sewing machine and said yarn guide finger has an opening therein adjacent its lower end through which the effect yarn is guided.
Claim 10
Independent Claim
28 words
An apparatus according to claim, 7 wherein said yarn guide finger has longitudinal grooves therein extending along both sides thereof and communicating with said yarn guide opening therein.
Claim 11
Dependent Claim
120 words
A yarn guide apparatus adapted to be used in association with a sewing machine for guiding an effect yarn to a reciprocable needle of the sewing machine for forming a textile article therefrom, said yarn guide apparatus comprising a yarn guide finger, and mounting means adapted for mounting said yarn guide finger adjacent the reciprocable needle of the sewing machine and for biasing the same into a predetermined first position in the path of reciprocation of the needle, and said mounting means being constructed for movement of said guide finger from said first position to a second position outwardly away from the path of reciprocation of the needle while the guide finger is being biased back to said first position.
Claim 12
Dependent Claim
120 words
A yarn guide apparatus adapted to be used in association with a sewing machine for guiding an effect yarn to a reciprocable needle of the sewing machine for forming a textile article therefrom, said yarn guide apparatus comprising a yarn guide finger, and mounting means adapted for mounting said yarn guide finger adjacent the reciprocable needle of the sewing machine and for biasing the same into a predetermined first position in the path of reciprocation of the needle, and said mounting means being constructed for movement of said guide finger from said first position to a second position outwardly away from the path of reciprocation of the needle while the guide finger is being biased back to said first position.
