Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 165 words
Apparatus for the sewing of fabric into garment components comprising, a support, a machine having sewing instrumentalities mounted upon said support and means for displacing the fabric in a predetermined path of travel during actuation of said sewing instrumentalities to stitch preselected portions of said fabric to form a stitch line having at least a portion at an angle with respect to the direction of travel of the fabric being sewn, said means including a member for clamping the fabric against said support, said member being rotationally fixed relative to said sewing instrumentalities, means for directing said member and fabric in a preselected path about said sewing instrumentalities, said means for directing said member including a follower member fixed relative to said support and sewing instrumentalities, and frictionally engaging and guiding a portion of said clamp member, and means for applying forces to said clamp member to yieldably maintain said clamping member in engagement with said fixed follower member during actuation of said sewing instrumentalities.
Claim 2
Dependent Claim 165 words
Apparatus for the sewing of fabric into garment components comprising, a support, a machine having sewing instrumentalities mounted upon said support and means for displacing the fabric in a predetermined path of travel during actuation of said sewing instrumentalities to stitch preselected portions of said fabric to form a stitch line having at least a portion at an angle with respect to the direction of travel of the fabric being sewn, said means including a member for clamping the fabric against said support, said member being rotationally fixed relative to said sewing instrumentalities, means for directing said member and fabric in a preselected path about said sewing instrumentalities, said means for directing said member including a follower member fixed relative to said support and sewing instrumentalities, and frictionally engaging and guiding a portion of said clamp member, and means for applying forces to said clamp member to yieldably maintain said clamping member in engagement with said fixed follower member during actuation of said sewing instrumentalities.
Claim 3
Dependent Claim 54 words
Apparatus for the sewing of fabric into garment components as recited in claim 1, said means for directing said clamp member and fabric in a preselected path including cam means on said clamp member for engaging said follower member adjacent said sewing instrumentalities for guiding said member and said fabric in a preselected path.
Claim 4
Dependent Claim 45 words
Apparatus for the sewing of fabric into garment components, as recited in claim 2, said means for applying forces to said clamp member including fluid power means for urging said member and fabric in a predetermined path relative to said cam means and sewing instrumentalities.
Claim 5
Dependent Claim 46 words
Apparatus for the sewing of fabric into garment components as recited in claim 1, and further including means for positioning and aligning preselected edge portions of said fabric in a prescribed manner and means for conveying the fabric having edge portions aligned to said displacing means.
Claim 6
Dependent Claim 47 words
Apparatus for the sewing of fabric into garment components as recited in claim 4, said means for positioning and aligning said fabric including means for displacing and positioning said fabric in a prescribed manner and for folding the fabric into an overlapped relation for aligning preselected portions.
Claim 7
Dependent Claim 36 words
Apparatus for the sewing of fabric into garment components as recited in claim 5, said displacing means clamping member having peripheral portions substantially conforming to and positioned in spaced relation to said fabric aligned, preselected portions.
Claim 8
Dependent Claim 60 words
Apparatus for the sewing of fabric into Garment components as recited in claim 1 said clamp member having a cam surface thereon, and said follower means including a cam follower positioned adjacent said sewing instrumentalities for engaging said clamp member cam surface to guide said clamp member and fabric in a predetermined path of travel during sewing of the fabric.
