METHOD FOR PLOTTING OF CURVE PATTERNS FOR ADJOINING PARTS OF SEWING ARTICLE Russian patent published in 2004 - IPC

FIELD: sewing industry. SUBSTANCE: method involves plotting production drawing; forming angular portion of adjoining part with acute angle and providing mirror reflection of point of intersection of normal with following outer contour line with respect to tangent to immediate initial contour line; drawing straight line through this point and point of intersection of tangents drawn to immediate initial contour line and to following outer contour line; finding point of intersection of straight line and tangent to immediate outer contour line. EFFECT: increased precision of plotting of curve patterns, reduced labor intensity and decreased material usage. 2 dwg
