Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 239 words
A process for making a panty comprising the steps of: a. placing two elastic ribbons in a stretched state along opposite horizontal edges of an elongated approximately rectangularly shaped fabric web; b. attaching the stretched elastic ribbons to the fabric web; c. folding those portions of the fabric web having the elastic ribbons attached thereto onto the remaining fabric web; d. attaching the respective folded portions of the fabric web and the elastic ribbons to one another; e. folding the fabric material along a fold line corresponding to an approximate longitudinal center line extending widthwise of the panty so as to form adjoining symmetrical panels in a face-to-face relationship; f. attaching said adjoining panels to one another along two spaced, approximately parallel cross directional lines of attachment defining a panty fabric area therebetween which will constitute the panty product; g. cutting the folded web along: 1. two cut lines which are substantially parallel to the cross directional lines of attachment and outside of the panty fabric area to sever the panty from said elongated web; and 2. two additional cut lines located on both sides respectively of a cross directional line passing through the approximate center of the panty area, each cut being made as the approximate mirror image of the other along a line passing through a point on the fold line and a second point on the adjacent cross directional cut line; thereby forming the panty product.
Claim 2
Dependent Claim 239 words
A process for making a panty comprising the steps of: a. placing two elastic ribbons in a stretched state along opposite horizontal edges of an elongated approximately rectangularly shaped fabric web; b. attaching the stretched elastic ribbons to the fabric web; c. folding those portions of the fabric web having the elastic ribbons attached thereto onto the remaining fabric web; d. attaching the respective folded portions of the fabric web and the elastic ribbons to one another; e. folding the fabric material along a fold line corresponding to an approximate longitudinal center line extending widthwise of the panty so as to form adjoining symmetrical panels in a face-to-face relationship; f. attaching said adjoining panels to one another along two spaced, approximately parallel cross directional lines of attachment defining a panty fabric area therebetween which will constitute the panty product; g. cutting the folded web along: 1. two cut lines which are substantially parallel to the cross directional lines of attachment and outside of the panty fabric area to sever the panty from said elongated web; and 2. two additional cut lines located on both sides respectively of a cross directional line passing through the approximate center of the panty area, each cut being made as the approximate mirror image of the other along a line passing through a point on the fold line and a second point on the adjacent cross directional cut line; thereby forming the panty product.
Claim 3
Dependent Claim 62 words
two additional cut lines located on both sides respectively of a cross directional line passing through the approximate center of the panty area, each cut being made as the approximate mirror image of the other along a line passing through a point on the fold line and a second point on the adjacent cross directional cut line; thereby forming the panty product.
Claim 4
Dependent Claim 62 words
two additional cut lines located on both sides respectively of a cross directional line passing through the approximate center of the panty area, each cut being made as the approximate mirror image of the other along a line passing through a point on the fold line and a second point on the adjacent cross directional cut line; thereby forming the panty product.
Claim 5
Dependent Claim 65 words
The process of claim 1 wherein the two elastic ribbons in step (a) are placed inwardly from the longitudinal edges of the web at a distance equal to about at least the width of the elastic ribbon and the following step (c) is accomplished by folding those portions of the fabric web between the elastic ribbons and their respective longitudinal edges onto the elastic ribbons.
Claim 6
Dependent Claim 62 words
two additional cut lines located on both sides respectively of a cross directional line passing through the approximate center of the panty area, each cut being made as the approximate mirror image of the other along a line passing through a point on the fold line and a second point on the adjacent cross directional cut line; thereby forming the panty product.
Claim 7
Dependent Claim 62 words
two additional cut lines located on both sides respectively of a cross directional line passing through the approximate center of the panty area, each cut being made as the approximate mirror image of the other along a line passing through a point on the fold line and a second point on the adjacent cross directional cut line; thereby forming the panty product.
Claim 8
Dependent Claim 170 words
A process for making a panty comprising the steps of: a. stretching two elastic ribbons; b. internally maintaining the elastic ribbons in their stretched state by freezing them while they are in their stretched state; c. placing two internally immobilized elastic ribbons along opposite horizontal edges of an elongated approximately rectangularly shaped fabric web; d. attaching the internally immobilized ribbons to the fabric web; e. folding those portions of the fabric web having the internally immobilized elastic ribbons attached thereto onto the remaining fabric web; f. attaching the respective folded portions of the fabric web and the internally immobilized elastic ribbons to one another; g. folding the fabric material along a fold line corresponding to an approximate longitudinal center line extending widthwise of the panty so as to form adjoining symmetrical panels in a face-to-face relationship; h. attaching said adjoining panels to one another along two spaced, approximately parallel cross directional lines defining a panty fabric area therebetween which will constitute the panty product; i. cutting the folded web along:
Claim 9
Dependent Claim 170 words
A process for making a panty comprising the steps of: a. stretching two elastic ribbons; b. internally maintaining the elastic ribbons in their stretched state by freezing them while they are in their stretched state; c. placing two internally immobilized elastic ribbons along opposite horizontal edges of an elongated approximately rectangularly shaped fabric web; d. attaching the internally immobilized ribbons to the fabric web; e. folding those portions of the fabric web having the internally immobilized elastic ribbons attached thereto onto the remaining fabric web; f. attaching the respective folded portions of the fabric web and the internally immobilized elastic ribbons to one another; g. folding the fabric material along a fold line corresponding to an approximate longitudinal center line extending widthwise of the panty so as to form adjoining symmetrical panels in a face-to-face relationship; h. attaching said adjoining panels to one another along two spaced, approximately parallel cross directional lines defining a panty fabric area therebetween which will constitute the panty product; i. cutting the folded web along:
Claim 10
Dependent Claim 65 words
The process of claim 3 wherein the two elastic ribbons in step (a) are placed inwardly from the longitudinal edges of the web at a distance equal to about at least the width of the elastic ribbon and the following step (c) is accomplished by folding those portions of the fabric web between the elastic ribbons and their respective longitudinal edges onto the elastic ribbons.
Claim 11
Dependent Claim 13 words
The process of claim 4 whereas the fabric web is a disposable material.
Claim 12
Dependent Claim 26 words
The process of claim 5 where the disposable material is a cross laid carded web assembly having a weight of about 15 to about 25 gm/yd2.
Claim 13
Dependent Claim 23 words
The process of claim 6 where the fibers of adjacent carded webs transverse one another at angles of about 30* to about 80*.
Claim 14
Dependent Claim 16 words
The process of claim 7 where the fibers transverse one another at angles of about 60*.
