Because the size of each cut piece of the seat cover depends on the actual size of the closed sponge of the seat, the material and the thickness of each cut piece and the weight and the thickness of the foam attached to the back surface of each cut piece, the thickness of the material and the thickness of the attached material need to be added after the initial version of each cut piece is taken according to the method, and more and less sizes need to be added, the traditional method depends on the experience of a platemaker, the added size standard is specially formulated here, as shown in figure 6, the material is microfiber leather, the periphery of the cut version of the seat cover needs to be widened by 1mm on the basis of the initial version, the material is cowhide, and the periphery of the cut version of the seat cover needs to be widened by 2mm on the basis of the initial version; the back of the material is attached with foam, the gram weight is 350-500 g/square meter, the thickness of the attached foam is 5mm, the periphery of the chair cover plate cutting template needs to be widened by 1mm on the basis of the original plate, the thickness of the attached foam is 8mm, the periphery of the chair cover plate cutting template needs to be widened by 3mm on the basis of the original plate, the thickness of the attached foam is 10mm, and the periphery of the chair cover plate cutting template needs to be widened by 5mm on the basis of the original plate; the back of the material is attached with foam, the gram weight is 550-1000 g/square meter, the thickness of the attached foam is 3mm, the periphery of the chair cover plate cutting template needs to be widened by 1mm on the basis of the original plate, the thickness of the attached foam is 5mm, the periphery of the chair cover plate cutting template needs to be widened by 2mm on the basis of the original plate, the thickness of the attached foam is 8mm, the periphery of the chair cover plate cutting template needs to be widened by 4mm on the basis of the original plate, the thickness of the attached foam is 10mm, and the periphery of the chair cover plate cutting template needs to be widened by 6mm on the basis of the original plate; based on the above, it is very important and necessary to make the above detailed copy book.
Step S2: the shape of the cutting piece of the chair cover is determined.
(1) And drawing a mounting modeling line. As shown in fig. 7 and 8, the seat back closed cotton 1 is sleeved on the seat back iron table 7 and fixed by decoration, a closed cotton center line 8 and a transverse section line 9 are drawn on the seat back closed cotton 1 by a black pen, and the center line 8 is perpendicular to the transverse section line 9. And then drawing the molding contour lines 3 of the cut pieces on the front side and the back side of the combined cotton, wherein the front side is provided with a molding groove area, the center line of the combined cotton groove is the molding contour line 3 of the cut pieces, and the corner lines of the combined cotton molding on the side surface and the back side are the molding contour lines 3 of the cut pieces. Specifically, the following are: when the central line and the transverse section lines are drawn, the transverse section lines need to be perpendicular to the central line, and the purpose of drawing the central line and the transverse section lines is to ensure that the appearance of the mounted seat is integrally square and smooth, and is attractive in appearance and free of the problems of deflection and the like.
(2) And drawing mark points. Setting mark points: (1) closing the center point of the cotton; (2) the nailing points are fixed by the chair cover; (3) the sewing accessories of the chair cover are as follows: starting points and end points of sewing such as fine cloth, a buckle strip, a zipper and the like; (4) special hole sites; (5) setting a mark line for the distance between the linear area point and the point from 150mm to 300mm, and setting a mark line for the distance between the arc area point and the point from 50mm to 100mm; (6) the starting point and the ending point at the corner of the chair cover; (7) the mark points 10 are all needed to be arranged at the joints of the chair cover, etc. (for example, the left/right back is distinguished by double mark points when the left/right back is relatively designed), (8) the joint of the chair cover is designed. The sewing mark 10 is provided to facilitate monitoring whether the shift and dislocation between the chair cover and the chair cover are generated during the sewing process at any time, and to facilitate timely correction. In addition, the mark points can also be used for determining the position of the seat cover batch when the leather is nailed and fixed, and the sewing accessories of the seat cover such as: the positioning positions of the starting point and the end point of the sewing such as the fine cloth, the button strip, the zipper and the like.
When the mark points 10 are drawn on the seat-back synthetic cotton 1, attention should be paid to arranging fewer mark points 10 at the straight line of the modeling line to reduce the workload, and arranging more mark points 10 at the arc-shaped modeling line to ensure that the fabric arc-shaped modeling line is sewn more accurately, and the sewing is automatically adjusted according to the actual sewing difficulty and effect. Theoretically, the more the mark points 10 are arranged on the cutting piece of the chair cover, the more accurate the sewing of the chair cover is. One criterion is set here: generally, in the straight part of the moulding line, as described above, one mark point 10 can be set every 150mm to 300mm, and in the arc part of the moulding line, one mark point 10 can be set every quarter of the total arc length or one mark point 10 can be set every 50mm to 100mm, so as to ensure that whether the sewing seam of the seat cover cutting piece A and the seat cover cutting piece B is displaced or dislocated at any time in the sewing process, thereby ensuring the accuracy of the moulding line.
And step S3: cutting pieces of the PC film and the double-sided adhesive tape chair cover are shaped.
As shown in figures 9 and 10, the point of the shaping step is to extract the shaping contour lines 3 and the mark points 10 of all the cover cut pieces (101-117) on the seat back sponge 1, and lay the extracted contour lines and mark points flat into a plane, so as to determine the shape of the shaping line on the plane and the area surrounded by the shaping line, and the shaping line is used for determining the shape and the area of the cover cut pieces in the later period. In this typing step, we can adopt the following new method: as shown in fig. 9, a common double-sided tape 11 is stuck on the molding contour 3 around the background 101 in the chair cover cut piece, as shown in fig. 10, a transparent PC film 12 having an area larger than the area of the background 101 is used to cover all the areas of the background 101, the molding contour 3 and the mark points 10 drawn on the back-fitted sponge 1 can be observed through the transparent PC film 12, and then each molding contour 3 and each mark point 10 on the background 101 are drawn on the PC film 12 by using a black oil pen. Note that, in order to overcome the problem that the PC film 12 usually laid on the synthetic cotton is wrinkled and finally causes a certain deviation from the actual shape in the background 101 of the taken out chair cover cutting piece, and the area deviation surrounded by the worst is made, the double-sided tape 11 is adopted, and when the PC film 12 is laid on the background 101, the PC film 12 is adhered to the double-sided tape 11, and even if the PC film is deformed or wrinkled, the double-sided tape 11 is adhered to ensure that the PC film 12 is not deformed or wrinkled. Note: besides the PC film, other visible materials such as nonwoven fabric may be used. The method needs to be implemented as follows: when the modeling contour line 3 and the mark point 10 are drawn by using a black oil pen, the transparency of the plastic film is high, and if a solid line is drawn, visual disturbance is caused, and the line is finally deviated, and the enclosed area is large or small, so that the line type of the rear closed line which is easy to observe, such as a dotted line and a dot-dash line, can be selected for drawing. After completion of drawing, the positions of the mark points 10 are marked, and it is checked whether or not there is a drawing deviation, and if there is a deviation, correction with a red oil pen is possible. In the other type taking process, the curved surface or the arc position is focused on, all places with folds are flattened, otherwise, the manufacture of a template is influenced due to incorrect type taking, and the quality of a finished chair cover is influenced finally.
And step S4: and (5) making an initial plate of a cutting piece template of the chair cover.
As shown in fig. 11 and 12, after the background 101 modeling contour line 3 and the mark point 10 are drawn, the PC film 12 is torn from the back synthetic cotton 1, unfolded and flattened and stuck on the cardboard 13, the background 101 is shaped, the background 102 is shaped by the same method, and the cardboard 13 is generally selected to be 0.8 to 1mm thick. In order to make the lines of the sewn chair cover smooth and attractive, the lines of the chair cover cutting piece template modeling contour lines 3 need to be smoother, the shapes of the chair cover cutting piece template modeling contour lines can be generally drawn by using a curve set gauge or an R gauge, so that the curves are smoother and more attractive, the curve set gauge comprises R30 to R5000, and the chair cover cutting piece template modeling contour lines with different sizes and radians can be drawn. After the modeling contour line 3 of the chair material cutting piece is drawn, the paperboard is cut along the modeling contour line 3, and then each chair cover cutting piece sample plate original plate can be obtained, and all the chair cover cutting pieces 101-117 on the back-combined cotton 1 are completely shaped according to the method.
Step S5: and measuring and checking the perimeter of the template.
Measuring the perimeter 14 between the mark points on all the chair cover cutting piece sample plates 101-117 in the background by using a small measuring tape with the 1M specification, and recording the measured specific numerical value on the sample plates. After the measurement is completed, the perimeter 14 between the opposing stitching templates needs to be checked. As shown in fig. 13, taking a background middle part 101, a background lower part 102, a back right belly 103, a back left belly 104, and a background upper part 113 of a chair cover panel as an example, the upper half part of the background middle part 101 and the lower half part of the background upper part 113 are sewn together, and their circumferences 14 need to be consistent, for example, there are 4 circumference 14 differences for the inner core of the circle of the drawing; the lower half part of the middle 101 of the background is sewn with the upper half part of the lower 102 of the background, and the circumferences 14 of the lower half part and the upper half part need to be consistent, and if the inner core pair of the circle of the figure is found, 2 circumference differences exist; in the background, the left side 102 is sewn with the left belly 104, and the right side is sewn with the right belly 103, so that the circumferences 14 of the left side and the right belly are consistent, and if the inner core pair of the circle of the figure is found, 2 circumference differences exist.
Step S6: perimeter difference verification and modification.
As shown in fig. 14, for the above-mentioned difference part of the circumference length 14, multiple measurements need to be combined with actual foam to ensure the accuracy of the circumference length 14 measurement. And modifying the circumference 14 difference template by adopting a circumference equal checking method. The perimeter equality check method, as the name implies, is that the perimeters 14 of two sewed chair cover cut pieces are required to be equal. Particular emphasis here is given to: the circumference equality check method is very important because when sewing the seat cover, as shown in fig. 13, 101 in the seat cover panel background is sewn with the seat cover panel 102, the distance between the mark point on 101 in the seat cover panel background and the mark point is equal to the distance between the mark point on the seat cover panel 102 sewn with it, and the distance between the mark point and the mark point is called the circumference 14. The lower half circumference 14 of the background 101 is equal to the upper half circumference 14 of the background 102 sewn with the lower half circumference; in the actual printing work, because the seat modeling is diversified and has different complexity, when the initial printing is usually taken, the modeling of each seat cover cutting piece cannot be completely consistent with the modeling of the actual back-combined sponge 1, which results in that the perimeter 14 of each sewn seat cover cutting piece is inconsistent, in order to ensure that the perimeters 14 of the sewn seat cover cutting pieces are consistent and the modeling of each seat cover cutting piece conforms to the actual modeling of the back-combined sponge 1, the perimeter equal checking method is adopted, so that the deviation of each cutting piece can be quickly found out, the correction is timely carried out, the efficiency is improved, in the actual production process of mass production, if the feedback of the mounting effect of the seat cover difficult to sew or the back-combined sponge 1 is not good, the real cause can be quickly found out by the perimeter equal checking method. Similarly, taking the middle part 101 of the chair cover panel background, the lower part 102 of the background, the right belly 103 of the back, the left belly 104 of the back, and the upper part 113 of the background as an example, as shown in fig. 14, there are four different circumferences 14 between the upper part 101 of the background and the lower part 113 of the background, and the four circumferences 14 of the background 101 are: 29mm, 27mm, 29mm, 113 these four places circumference 14 on the background are respectively: 33mm, 29mm, 30mm and 31mm, the difference is respectively 4mm, 2mm, 3mm and 2mm, the perimeter of the four positions of the lower half part of the upper 113 of the background is adjusted according to the perimeter equality check method, the perimeter is respectively trimmed by 4mm, 2mm, 3mm and 2mm, and the lower half part of the upper 113 of the background is consistent with the perimeter 14 of the upper half part of the middle 101 of the background. According to the method, the circumference of the upper half part of the plate 102 under the background is trimmed by 3mm and 5mm, the circumference of the right belly of the back is trimmed by 3mm, the circumference of the right belly of the back is trimmed by 103 mm, the sample plate 104 of the left belly of the back is trimmed by 5mm, the difference correction of the sample plates is completed, and the original plates of the sample plates from 101 to 117 are modified one by one according to the method.
Step S7: adding the template edge distance and the mark points. As shown in fig. 15, the original plate is extracted by the above method, and the car seat cover is sewn, the original plate is added with the sewing edge distance 6, as shown in fig. 1, the chair cover is mounted on the artist's book, the sewing edge distance is 10mm, so all the original plates are added with the sewing edge distance 6 of 10 mm. In addition, the mark points on all the templates are changed from a straight shape to a triangular shape, and the triangular mark points are as follows: the length is 5mm, the width is 5mm, and the triangular mark points are convenient for confirming whether the chair cover and the chair cover are displaced or dislocated in the sewing process, so that the sewing is ensured to be correct.
Step S8: and (5) finishing the template. All the templates are finished by the above method, and the manual is mounted on the contrast chair cover, and all the templates are checked, as shown in fig. 16. One more mark points 10 are additionally arranged on one of the left and right similar chair cover cutting piece templates, and whether mark points 10 are arranged at the starting point and the end point of the chair cover sewing accessories such as a buckle strip, a zipper, a piece of fine cloth, a tube strip and the like needs to be confirmed, so that the template is completely manufactured.
After the template is finished, a chair cover sewing sequence is manufactured, and subsequent on-site sewing is strictly carried out according to the sewing sequence, so that the chair cover sewing quality and the mounting quality are ensured. As shown in fig. 16: the stitching sequence NO1 to NO6 is: the left back belly 104, the left back belly 105 and the left back belly 107 are sewn, the decorative thread 2 is sewn on the left back belly 104 and the left back belly 107 through a single needle, the right back belly 103, the right back belly 106 and the right back belly 108 are sewn, the decorative thread 2 is sewn on the right back belly 103 and the right back belly 108 through a single needle, and then the left part, the right part and the lower part 102 of the background are sewn on the lower half part of the chair cover.
