Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a basic formula of an active layout drawing in pants tailoring and more particularly a basic formula to measure the figure of human body so as to alternatively fit the differences in body figure.

[0002] Regular layout drawing in tailoring is unvarying and can not help to discover the defect in body figure for conpensation in advance, thereby misfit happens quite often and further alteration is usually required. Therefore, regular layout drawing technique is not perfectly applicable in mass production. The main object of the present invention is to provide a right technique in body figure measurement and a basic formula of active layout drawing in pants tailoring so as to promote the quality, reduce the loss, and increase the productivity and the profit.

[0003] Another object of the present invention is to provide an active layout drawing technique such that the dress maker can easily handle with the variation in body figure while tailoring to prevent any further alteration.

according to the distance equal to the difference between the measure (O) (72cm in the embodiment) and the length of the gore in the front piece (30cm), draw a line from the point (4) through the point (44) to connect the curved line (45) up to the point (40); according to the length of the gore in the back piece (42cm in the embodiment) draw a line from the point (85) through the line (86), the point (87), the point (90), the point (93) and the point (7) and extending outward to a point (119) in an arch shape to complete a gore line for the back piece; according to the internal side length of the front piece, draw a line from the point (74) through the point (72) to connect the line (43) up to the point (40) so as to complete an internal side line for the back piece (68cm in the embodiment), then, according to the distance equal to the internal side length of the front piece minus 1.5cm (68cm - 1.5cm = 66.5cm) draw a curved line from the point (118) through the point (116) to connect the point (119) so as to complete an internal side line (120) for the back piece, thus the basic model (S) for the back piece is completed; for the folding part of the front piece at the waist line, process as follows:
1/4 of the measure (B) = the length between points (28) and (105) - the width for the waist line in the front piece = the folding part at the waist line,
the width for the abdomen 1 from the point (87) to the point (112) - 1/4 of the measure (D) - the length between points (27) and (107) in the front piece = the folding part at the abdomen. for the folding part of the back piece at the waist line, process as follows:
1/4 of the measure (B) - the length between point (28) and point (105) - the width for the waist line in the back piece = the folding part at the waist line,
the width for the abdomen 1 from the point (87) to the point (112) - 1/4 of the measure (D) - the length between points (27) and (107) in the front piece = the folding part at the abdomen.
