Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing shoulder pads for clothing by an efficient cutting and forming method.

With recent advances in sewing technology, so-called ready-made clothing has become mass-produced, and the demand for shoulder pads for use in the shoulders of men's suits has correspondingly increased.

As shown in Figure 1, normal shoulder pads have a semicircular shape (Figure 1-A, C) with an arcuate cross section (Figure 1-B).
By inserting this into the shoulder area of clothing and sewing it, it accentuates the style and design of the clothing and prevents it from losing its shape. Conventional methods for making shoulder pads for clothes include stacking and sewing several nonwoven fabrics of different sizes with a thickness of about 2 to 4 mm, and cutting sponge into crescent shapes. The former method requires many steps such as punching, overlaying, and sewing processes, resulting in poor workability, while the latter method requires cutting shoulder parts one by one, which is inefficient. The shape of the resulting shoulder pads is also uniform, and there is a disadvantage that there is a lot of loss of sponge.

The object of the present invention is to improve the drawbacks of the above-mentioned method of manufacturing shoulder pads, and to manufacture shoulder pads by efficient and economical cutting and forming.

The object of the present invention is to insert an elastic raw material selected from fiber entangled material, felt, and sponge between a pair of templates in which a plurality of male and female molds corresponding to circular disks having an arcuate cross section are arranged in parallel. , the compressed thickness of the original fabric is
When cutting the original fabric in the horizontal direction with a slicer while holding the template under pressure so that the thickness is 50 to 80%, first cut the lower male mold and the upper female mold by inserting the male mold into the convex part of the male mold. The original fabric is placed under pressure so that the recesses of the female mold and the female mold are perfectly aligned vertically, and slices are cut in the horizontal direction at positions close to the female mold. After taking out the continuous cut raw fabric and the residual raw fabric on the male die side, the male die and female die are shifted from each other by the radius of the disk, and the above-mentioned die is placed in the position where the convex part of the male die was originally. The above-mentioned residual original fabric is inserted upside down between templates with an auxiliary male die having the same shape as the disk, held under pressure, and sliced horizontally at a position close to the female die. The two-stage slicing method is used to obtain two cut original fabrics in which circular disks each having an arcuate cross-section are continuous, and then the disks having an arcuate cross-section are separated from the cut original fabric, and this disk is divided into two parts in the diametrical direction. This can be effectively achieved by a method of manufacturing shoulder pads.

The raw material (original fabric) for the shoulder pads of the present invention is selected from bulky and elastic materials such as fiber entanglement, felt, and sponge. Synthetic fiber monofilament is crimped, cut into pieces of approximately 50 to 150 mm, and the mixture is treated with an adhesive to bond and fix the bonding points of the monofilaments.
Other materials that can be used include felt and urethane sponge, which are commonly used as raw materials for shoulder pads. These original fabrics generally have a thickness of about 30 to 60 mm and are sized to correspond to the templates described below.

When manufacturing the shoulder pads of the present invention, the original fabric is first subjected to two-stage slicing and cut into a plurality of arcuate cross-section discs. It consists of a pair of male and female types arranged in parallel. Cross-sectional views of the male and female molds are shown in Figures 2 and 3, and when viewed from above, at least 4 rows and 4 rows of cut arcuate discs are arranged in parallel in the vertical and horizontal directions. It turns out. The materials for the male and female molds are not particularly limited, but materials made of hard rubber plates are suitable from the viewpoint of their shapeability and the fact that they do not damage the slicing blades.
The dimensions of the arcuate cross-sectional disk formed on the template are appropriately selected depending on the desired shape of the shoulder patch, but are usually in the range of 150 to 200 mm in diameter and 15 to 25 mm in maximum height. Note that the template may be provided with a stopper for pressurizing and gripping the template or a connecting point thereof.

Next, each stage of two-stage slicing is shown in Figures 2 and 3.
This will be explained according to the diagram.

When slicing in the first stage, as shown in Figure 2, first place the male die 1 at the bottom and the female die 2 at the top, so that the convex part of the male die and the concave part of the female die are perfectly aligned vertically. and insert the original fabric 3 between them. In this state, clamp the template and use appropriate means such as pressing to reduce the thickness of the original fabric to 50 to 80% of the original thickness.
Apply pressure so that it becomes , and hold it in that state. At this time, if the compressed thickness is 80% or more, the shaping of the original fabric is insufficient, and if it is less than 50%, horizontal slicing becomes difficult, which is not preferable. Next, while holding the template under pressure, the original fabric is cut by passing it through a slicing blade in a horizontal direction from the center line of the female die (as indicated by the chain line in Figure 2). By this first stage of slicing, the original fabric is cut into a cut original fabric A with a continuous arcuate cross-sectional disk on the female side and a residual original fabric B on the male side.

In the second stage of slicing, as shown in FIG. An auxiliary male die 4 having the same shape as the disk is installed so that a male die similar to the first slice is present at the position where the convex portion was present. Next, the residue material B obtained in the first slicing is turned over between the templates arranged as above, and inserted so that its convex part matches the concave part of the female die 2, and the same compression as in the first slicing is performed. The template is held under pressure so that it has the same thickness, and the female mold is cut horizontally (as shown by the chain line in Figure 3) through a slicing blade. The auxiliary male mold 4 used here functions to compensate for the missing portion in the first slice of the residual original fabric 4 and to pressurize and grip the residual original fabric uniformly and stably. By this second stage slicing, the residual raw fabric B is divided into two parts: the cut raw fabric C, which has a continuous arcuate circular cross section, and the extremely thin residual fabric D.

The two-stage slicing process described above allows two cut sheets A and C to be obtained from one sheet of the original sheet, so the amount of waste material to be discharged is extremely small, and efficient and economical cutting can be achieved. be.

The thus obtained cut material has circular disks arranged in a row in a continuous manner, and by punching it with a semicircular shoulder patch blade, for example, a Thomson blade, it is possible to obtain the shoulder patch in the shape shown in Figure 1. can.

The shoulder pad thus obtained can be used as it is, but if desired, it can also be covered with a nonwoven fabric and sewn into a product. In addition to shoulder pads, products made according to the present invention can also be used as hats and shoe inserts.

According to the method of the present invention, for example, by arranging male and female disks in 6 columns and 6 rows, 36 disks×
2, a total of 72 discs, and 142 semicircular shoulder pads can be completed at once from these discs, greatly improving work efficiency compared to conventional methods. Furthermore, it is economical because the amount of residual raw fabric is extremely small, and it also has the advantage that by changing the template, it can easily accommodate changes in the shape of the shoulder pads due to diversification of designs.

The effects of the present invention will be further explained below with reference to Examples.

Example 1 Same as above with a male mold in which hard rubber arcuate disc protrusions with a circular diameter of 180 mm and a maximum height of 15 mm are arranged in 4 rows and 5 rows and adhered to a hard rubber mat with a thickness of 5 mm, a width of 750 mm, and a length of 1100 mm. Shape of hard rubber pine to circular diameter
A female mold was prepared in which concave hard rubber disks with an arcuate cross section of 180 mm and a maximum depth of 16 mm were glued in an array of 4 rows and 5 rows.

On the other hand, a raw fabric consisting of a fiber entangled body with a thickness of 28 mm, width of 750 mm, and length of 1100 mm was prepared by crimping approximately 130 denier nylon 6 monofilament, cutting it into 80 mm pieces, and entangling them with adhesive. Prepared.

Next, place the male mold on the lower stage and the female mold on the upper stage, facing each other as shown in Figure 2, insert the original fabric between them, and clamp the molds under pressure such that the thickness of the original fabric becomes 20 mm. The sample was cut using a slicer (band machine manufactured by Kitamura Kikai Kogyo Co., Ltd.) while holding the space between the templates with a stopper. First, after passing the slicing blade horizontally 18 mm below the deepest part of the female mold, the mold plate was opened and there were 4 rows and 5 rows (20 ) The continuous sheets and the remaining sheets were taken out.

Next, shift the male and female molds by the radius of the disk,
Then, install an auxiliary mold to make the mold configuration as shown in Figure 3, insert the above-mentioned residue sheet upside down, and tighten the mold under pressure to the same compression ratio as above, and press the mold from the deepest part of the female mold to 18 cm.
By passing the slicing blade horizontally below the slicing blade, two rows and two rows (14 pieces) of arcuate semicircular disks with a maximum thickness of 24 to 25 mm and a bottom thickness of 2 to 3 mm, and three arcuate disks with a cross section of 2 rows and 2 rows (14 disks) 4 rows (columns) (12 sheets) continuous sheets and thickness 3~
A 20 mm uneven waste sheet was obtained.

Each of the two continuous sheets obtained above was punched out into shoulder pad shapes using the Thomson punching method, yielding 78 shoulder pads having the shape shown in Figure 1.
