Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 221 words
A fabric-pleating guide for pleating curtains or the like formed by an elongated body foldable at delineated intervals along its longitudinal extent into an accordion-type folded configuration, said body comprising a single ply material, plural stiffening elements arranged in a prescribed spaced relationship disposed on said body to form said foldable body so as to be foldable along fold lines defined by the spacing between said stiffening elements, said elements being substantially similar to one another with each element being generally rectangularlyshaped, said spacings being substantially equal to one another with each spacing defining one fold line, said similar elements and said equal spacings providing uniform pleats with each pleat including two elements, said body during use being operatively arranged in an unfolded condition against said fabric and thereafter folded in unison into said accordion-type folded configuration to thereby produce pleats in said fabric, said foldable body being additionally foldable along a longitudinally orientable fold line locatable along the medial portion thereof, said longitudinally orientable fold line being defined by a medial spacing disposed between said stiffening elements, said medial spacing transversing said equal spacings, whereby said body is adapted to close upon a fabric edge inserted therebetween as a result of foLding thereof along said longitudinally orientable fold line to thereby more firmly grip said fabric during the pleating thereof.
Claim 2
Dependent Claim 221 words
A fabric-pleating guide for pleating curtains or the like formed by an elongated body foldable at delineated intervals along its longitudinal extent into an accordion-type folded configuration, said body comprising a single ply material, plural stiffening elements arranged in a prescribed spaced relationship disposed on said body to form said foldable body so as to be foldable along fold lines defined by the spacing between said stiffening elements, said elements being substantially similar to one another with each element being generally rectangularlyshaped, said spacings being substantially equal to one another with each spacing defining one fold line, said similar elements and said equal spacings providing uniform pleats with each pleat including two elements, said body during use being operatively arranged in an unfolded condition against said fabric and thereafter folded in unison into said accordion-type folded configuration to thereby produce pleats in said fabric, said foldable body being additionally foldable along a longitudinally orientable fold line locatable along the medial portion thereof, said longitudinally orientable fold line being defined by a medial spacing disposed between said stiffening elements, said medial spacing transversing said equal spacings, whereby said body is adapted to close upon a fabric edge inserted therebetween as a result of foLding thereof along said longitudinally orientable fold line to thereby more firmly grip said fabric during the pleating thereof.
Claim 3
Dependent Claim 33 words
A fabric pleating guide as defined in claim 1 wherein said body is formed of cloth fabric and said stiffening elements are formed of a resin curable to a stiff or hardened material.
Claim 4
Dependent Claim 132 words
A fabric-pleating guide for pleating curtains or the like formed by an elongated body foldable at delineated intervals along its longitudinal extent into an accordion-type folded configuration, said body comprising a single ply material, plural stiffening elements arranged in a prescribed spaced relationship disposed on said body to form said foldable body so as to be foldable along fold lines defined by the spacing between said stiffening elements, said body during use being operatively arranged in an unfolded condition against said fabric and thereafter folded in unison into said accordion-type folded configuration to thereby produce pleats in said fabric, and an elongated spacing member joined to an edge of said body so as to extend lengthwise thereof and effective to serve as a spacing guide for successive pleating locations along said fabric.
Claim 5
Dependent Claim 132 words
A fabric-pleating guide for pleating curtains or the like formed by an elongated body foldable at delineated intervals along its longitudinal extent into an accordion-type folded configuration, said body comprising a single ply material, plural stiffening elements arranged in a prescribed spaced relationship disposed on said body to form said foldable body so as to be foldable along fold lines defined by the spacing between said stiffening elements, said body during use being operatively arranged in an unfolded condition against said fabric and thereafter folded in unison into said accordion-type folded configuration to thereby produce pleats in said fabric, and an elongated spacing member joined to an edge of said body so as to extend lengthwise thereof and effective to serve as a spacing guide for successive pleating locations along said fabric.
Claim 6
Dependent Claim 42 words
A fabric pleating guide as defined in claim 1 including an elongated spacing member joined to an edge of said body so as to extend lengthwise thereof and effective to serve as a spacing guide for successive pleating locations along said fabric.
