Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for manufacturing garment pads, particularly brassiere pads or shoulder pads, from soft sponge material.

<Prior Art> Bra pads and shoulder pads have a curved plate shape, and are thick at the center and thin at the periphery. Conventionally, when manufacturing such a pad using soft sponge, a soft sponge board of a certain thickness is cut out to the desired contour, and the cut out board is cut out with a large gap in the center and a small gap in the periphery. It was pressed into the desired shape using a press mold with a certain processing space.

<Problems to be Solved by the Invention> The pad manufactured as described above has a density that increases toward the periphery in inverse proportion to the decrease in thickness, so the periphery becomes harder, and this tendency The center part is thick and thick, so the culm is 4 Ui...Male culm 1-thick. in this way,
If the periphery is hard, it will not conform well to the body, and when you exercise, the edge will lift up from the body, making it difficult to sew because the sewing machine needle will not penetrate easily, and the sewing machine needle will easily break. In addition, it is difficult to manufacture such a pad with a deep curve as the raw material is thicker, and the pad tends to return to its original shape over time or with use, making it difficult to obtain a pad with a thick and soft center. This is because when the raw material is thick, a large tension is applied to the outer surface of the center when it is bent by heat pressing, and as a result, compressive force appears in the center of the raw material, reducing the wall thickness. This is due to tension or internal stress remaining inside the product.

Means for Solving Problems> In the present invention, similarly to the prior art, the cut intermediate material is processed using a hot press having a processing space in which the gap width is large in the center and the gap width is small in the peripheral area. Heat press using a mold. However, the intermediate material for this hot pressing is cut from a soft sponge plate with parallel surfaces, thick in the center and thin in the periphery.

<Function> According to the above-mentioned manufacturing method, even if the center part of the intermediate material is extremely thick, the tension that appears on the outer surface of the center part during bending by heat pressing is small, and therefore the wall thickness of the center part is reduced during heat pressing. Since it is possible to prevent the material from shrinking and to prevent it from curving or returning due to residual stress, it is easy to manufacture products with a thick center and a deep curvature.

Moreover, the product has thin peripheral parts and is very soft.
It conforms well to the body, stays in close contact with the body during exercise, and is extremely easy to sew.

<Example> In FIG. 1, l is a flat polyurethane foam. If this is first sliced by the cutting surface 2 which is wavy in the cross section parallel to the axis X as shown in (a), (

・Grooves 4, 4, etc. are formed. Next, when this is further sliced by a cutting surface 5 that is wavy in the cross section parallel to the axis Y perpendicular to the axis X, independent peaks 6.6
... is formed. In (d), one 6-thick peak was extracted by cutting along line 7.7. An intermediate material 8 having a desired contour is cut out around this mountain 6.

As shown in (e), the intermediate material 8 is hot pressed using a hot press mold 9. The mold 9 consists of a male mold 10 and a female mold 11, and the processing space 12 at the time of closing has a large gap width Da in the center and a small gap width Db in the peripheral area. By closing the mold, the intermediate material 9 is subjected to hot pressing, producing a cup-shaped pad 13 with a thick center portion and thin peripheral portions as shown in (f).

The pad 13 obtained as described above is thick and soft at the center, and small and still soft at the periphery.
There is almost no return of curvature over time or due to use.

<Effects of the Invention> As described above, according to the present invention, the central part is thick and the peripheral part is thin, and from the central part to the peripheral part there is a

It is possible to get a putt made by tapping. Therefore, the product conforms well to the body, is easy to sew, and can be used for a long period of time. In addition to this.

It is also possible to easily obtain products with very thick walls in the center or products that are curved or deep.
