Description

one

This invention relates to the apparel industry, in particular, to methods for constructing pants templates.

A known method for constructing a trouser template is to determine the position of the vertical axial lines of the front and rear halves of the pants, horizontal lines of the waist, hips, height of the seat, knee, bottom, side step and middle sections of the pants and balance the rear half of the pants 1.

The disadvantage of this method is the lack of construction of a line for pressing the back half of trousers, which leads to a deterioration in the appearance of the products due to the inconsistency of the finished trousers with the designed one, since the line of pressing in this method is obtained arbitrarily in the process of wet-heat treatment of the trousers.

The purpose of the invention is to improve the quality of the product by graphically determining the line of slacks at the bottom of the trousers half.

The goal is achieved by the method of constructing a template of trousers carried out by determining the position of the vertical v

the centerline of the front and back halves of trousers, horizontal lines of the waist, hip, height of the seat, knee, bottom, side and step cuts and mid-section line and balance of the back half of the pants, improving the quality of the product by graphically drawing the waist line of the back half of the pants balance lines on the centerline of the back half determine the position of the point corresponding to the position, the top

10 points of the slacking line, through which the wire is horizontal, then along the line of the step cut of the back half of the trousers from the line of the knee, lay down the value equal to the amount of delay of the step slice, the resulting point is combined with the point of intersection of the axial line with the horizontal line of the knee, obtaining additional nntelny line of the knee, which is restored perpendicular p and from the point of intersection with the line of the hips along the latter in the direction

Claims (1)

20 of the side slice lay a cut equal to half the width of the back half of the pants, and from the end of this cut an arc is drawn towards the middle slice with a radius equal to the sum of the distance from the cut to the intersection point of the restored knee with the horizontal line f to the vertical orange line, and the lengths of the step cut of the back half of the trousers, and the intersection point of this arc with the mid-section line is connected to the intersection points of the perpendicular restored to the additional line knees with knee thigh lines. The drawing shows the construction of the line zasyuzhki on the back half of the pants. The drawing line is drawn as follows. Determine the position of the highest point of the mid-section of the balance — the point Tz, from which the segment defining the position of the upper point of the pressing line of the back half of the TzT4 lay down along the center line of the TN. From point T4 to the left, perpendicular p to TH is restored. On the extension of the line of the knee and the bottom lay segments KjKs HiHs. Points Кз and Нз connect direct. From the point Kz, the KzK4 section is laid down, equal to the step cutoff length during wet-heat treatment. Perpendicular p to the KK4 line is restored from point K, its intersection point with the line defining the position of the top point of the smoothing line is denoted by TS, the seat height is I4. From the point I am on both sides; the segment is equal to W ,, „- (I, I-YaJ,) where is the width. back half of trousers; HS and Yav are endpoints. From the HS point, a wire with a radius equal to the center of the HsTs segment and the average cutoff length of the cut is made a notch on the line defining the position of the top point of the pressing line, and receiving the top point Tg or 1 of the pressing. With a smooth line of the point T, JA, K, N, get a line zatyuzhki. The construction of the rear half is carried out in a known manner, then the product is cut according to the obtained pattern. The cut back half of the trousers is folded in the axial direction, the stitch and side cuts are combined, subjected to wet thermal processing, and the stretch of the middle and step sruzy is done until the bend line is aligned with the applied smoothing line, and then bending of the fold. Then, the halves of the trousers are ground and processed. The proposed method allows you to ensure that the trousers have a different degree of fit that is predetermined in advance, varying the length of the cuts during wet-heat treatment, see the strength of the trousers before cutting and sewing and controlling it, controlling the amount of pitch of the stepper and medium sections of the back half of the pants when wet heat treatment, reduce labor costs for wet heat treatment, eliminating the need for rework. The invention method of creating a template of pants by determining the position of the vertical centerline of the front and rear halves of trousers, horizontal lines of the waist, hips, height of the seat, knee, bottom, side and step cuts and lines of the middle section and the back half of the pants, characterized in that The goal is to improve the quality of the product by graphically plotting the waist line of the back half of the trousers; after determining the position of the balance line on the center line of the back half, the position is determined by a point corresponding to the top position The points of the slack line through which the horizontal is conducted, then along the line of the step cut of the back half of the trousers from the line of the knee. Down is deposited a value equal to the length of the step of the step slice, the resulting point is connected to the point of intersection of the centerline with the horizontal line of the knee to obtain an additional line the knee, to which the perpendicular is restored, and from the point of intersection with the line of the thighs, along the length of the lateral cut-off, lay a segment equal to half the width of the back half of the trousers, and from the end of this section and carried towards middle cutoff arc radius equal to the sum of distances from the end of the segment to the intersection point perpen- reduced. The diculum to the additional line of the knee with the horizontal drawn to the vertical axial line and the length of the step cut of the back half of the trousers, and the intersection point of the arc with the middle cross section is connected to the intersection points of the perpendicular to the additional line of the knee from the line mi thighs and knees.
