Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to brassieres, chemises, body suits, etc.
The present invention relates to a method of manufacturing women's underwear having a cup portion, and relates to a method of manufacturing women's underwear having a cup portion that allows a desired cup size to be easily obtained.

[Prior art]

Conventional women's underwear with a cup part is either made by cutting the fabric so that the cup part is three-dimensionally formed by sewing, or the cutting is difficult and the sewing is troublesome, and the 0-join part is also noticeable. Therefore, if the cup part is made of knitted fabric made of thermoplastic fibers or the interlining is made of nonwoven fabric or thermoplastic resin sponge, it is necessary to create a three-dimensional pattern that is overlapped with the net fabric or interlining. The cut knitted fabric is cut to a size with enough gripping allowance, and the gripping allowance of the cut knitted fabric is inserted into the outer periphery of the recess of the female mold by inserting pins or tightening it with a frame. After fixing the fabric, etc., the cut knitted fabric, etc. is shaped into a cup shape by pushing the male mold into the fi-shaped recess and heating the cut knitted fabric, etc. using the heater built into the male mold or the steam blown out from the hole provided in the male mold. It was also practiced to mold the molded knitted fabric into a shape, and then use the molded cut knitted fabric with the gripping allowance removed for the cup part. If the cup part is three-dimensionally formed by molding K, it is easy to cut, easy to sew, and the seams are less noticeable, but the loss of the silk material from the gripping section that is removed is 30 to 40%. In addition, there is a problem in that so-called papering, in which the gloss increases when the knitted fabric is crushed in the cup portion, is likely to occur. Furthermore, whether the cup part's three-dimensional shape is formed by cutting or molding, the three-dimensional shape is determined before sewing, and the cup can be tailored to suit each wearer. It is not possible to change the shape of the part.

[Purpose of the invention]

The present invention was made in order to solve the above-mentioned problems with the conventional women's underwear having a cup part, and the cup part is molded by molding, so it is easy to cut and sew, and it is made of knitted fabric. To provide a method for manufacturing women's underwear having a cup portion that causes less loss, is less likely to cause haze in the cup portion, and allows the size of the cup portion to be easily set to suit each wearer.

[Structure of the invention]

The present invention uses a knitted fabric made of thermoplastic fibers in at least the portion that corresponds to the cup portion, and then sews women's underwear having a cup portion that is not three-dimensionally shaped, and then the cup portion extrusion mold protrudes. The chest fabric of the underwear is fixed with a pair of gripping plates that have holes to form and are overlapped to pinch the fabric around the holes, and then the cup part is extruded from the back side of the underwear to the front side through the holes of the gripping plates. The present invention provides a method for manufacturing women's underwear having a cup portion that protrudes, and heats the protruding cup portion of the underwear. With this configuration, the above object is achieved.

〔Example〕

The present invention will be explained below using illustrated examples.

Fig. 1 is a top view showing the state in which the brassiere is fixed with a grip plate, Fig. 2 is a sectional view of the main part of the apparatus for forming the cup part of a brassiere, and Fig. 3 is a view of the apparatus for forming the cup part of the sleeve. It is a schematic diagram.

In Figures 1 and 2, 1 is a sewn brassiere with a cup that is not three-dimensionally formed, 2 is an upper grip plate, 3 is a lower grip plate, 4 is a handle for tightening, and 5 is a cup. 6 is a mold base, 7 is a mold fixing plate, 8 is a fluid conduit, 9 is a switching pulp, IO is a heating fluid conduit, and 11 is a cold air conduit. The bra 1 is sewn using a knitted fabric made of thermoplastic fibers or an interlining made of a nonwoven fabric or a sponge notebook made of thermoplastic resin for the cup portion 1a, and for the other parts using the same materials as those used in conventional bras. Since the cup part does not have to be formed three-dimensionally, cutting and sewing are easy, and the number of mating parts in the cup part can be reduced. Fixing this bra 1 with the grip plate 2゜3 requires no tightening.
When the handle 4 is rotated from the outward facing position shown in FIG. K so that the nozzle handle 4 can be pulled out from the lower grip plate 3.
Therefore, when the nozzle 4 is pulled up in this state, the upper grip plate 2 is also pulled up together with the key part 4a and can be separated from the lower grip plate 3. Then, the brassiere 1 is placed on the lower grip plate 3 with the inside side. Place it face down as shown in FIG. 1, and do the rest by tightening the upper grip plate 2 to the lower grip plate 3 using the handle 4, rather than in the groove.

This fixation of the brassiere l is carried out by gripping by engagement of convex portions and recesses provided around the holes 2b, 3b of the gripping plate 2.3 through which the cup extrusion die 5 can protrude. After fixing the brassiere 1 with the gripping plates 2.3 in this way, the lower gripping plate 3 is lowered by a lifting means (not shown).
A cup part extrusion mold 5 fixed to a mold stand 6 is projected into the holes 2b and 3b of the gripping plates 2 and 3. At that time, the switching valve 9
The heating fluid, i.e., hot air or steam, is fed into the cup extrusion die 5 by the following steps.

The cup part extrusion mold 5 is made of porous metal or ceramics, and is not only heated by the heating fluid, but also discharges the heating fluid.
Heat a. Accordingly, the cup part 1 of the bra L
The grip plate 2.3 is lowered and the cup part extrusion die 5 protrudes from the holes 2b and 3b, thereby forming a three-dimensional shape. By adjusting the amount of protrusion of the cup extrusion die 5, the size of the cup can be matched to the wearer. Then, the lowering of the grip plate 2.3 is stopped at an appropriate protrusion amount, and the switching valve 9 is switched to feed cold air to cool the cup portion 1a. As a result, the three-dimensional shape of the cup portion 1a is set, and when the cup portion has cooled down, the grip plates 2 and 3 are raised and the brassiere 1 is removed from the grip plates 2 and 3.

With the above steps, it is possible to easily make a brassiere with an appropriate cup size. According to this method, for example, a wholesaler or a retail store can prepare a brassiere whose cup part has not been three-dimensionally molded, mold the cup part to an appropriate size according to the customer's request, and give it to the customer. This can reduce problems with inventory management and unsold items.

In addition, the size of the cup part is not only changed by simply changing the protrusion amount of the cup part extrusion mold 5, but also the grip plate 2.3 is
b, 3b may be replaced with a different shape or size, or the cup extrusion mold 5 may be replaced with a different shape, or the cup extrusion mold 5 may be replaced with a different shape or size.
You may also change the slope of By doing so, it is possible to provide a brassiere with a cup size that is more suitable for each wearer.

In FIG. 3, the same reference numerals as those in FIG.
For 2a, a knitted fabric made of thermoplastic fibers or an interlining made of non-woven fabric or a sponge sheet of thermoplastic 8:resin is used, and the other parts are sewn using the same materials as in conventional chemises, and the cup part is sewn. Since it does not need to be formed three-dimensionally, it is easy to cut and sew, and the cup portion requires fewer stitches. This chemise 12 is fixed with the grip plate 2.3 by lifting the upper grip plate 2 by the elevating arm 2a and separating it from the fixed lower grip plate 3, and then pushing out the middle lower grip plate 3 and the cup part of the chemise 12. Chemise 1 so that mold stand 6 with mold 5 attached, fluid conduit 8, etc.
2 so that the cup part 12a is at the position of the hole 3b of the lower grip plate 3, and then insert the upper grip plate 2 into the lower grip plate 3.
This is done by lowering it with K until you press . The holding plate 2.3 fixes the schmie<I'12 by holding it at the eyebrows of the holes 2b and 3b, as in the case of the brassiere I. After fixing the chemise 12, raise the mold table 6 using the lifting screw 13 and push out the cup part mold 5.
are made to protrude into the holes 2b and 3b of the gripping plates 2 and 3. At this time, the heating fluid is fed into the cup extrusion die 5 as in the case of the brassiere I, and the cup extrusion die 5 is suitably used.

The same goes for switching to cold air and setting it after it is projected with the appropriate projection at. After the cup portion 12a has cooled down, the mold stand 6 is lowered to its original position, the upper grip plate 2 is raised, and the chemise 12 is removed.

As described above, as in the case of the brassiere l, the chemise 12 having an appropriate cup size can be easily made. Of course, to change the three-dimensional shape of the cup part, the gripping plates 2, 3 and the cup part extrusion die 5 may be replaced. Alternatively, the chemise 12 may be fixed to the grip plates 2 and 3 by inserting it from the hem side.

Although the examples of a brassiere and a chemise have been described above, the present invention is not limited thereto, and can also be applied to body suits and the like.

〔Effect of the invention〕

According to the present invention, it is possible to easily provide underwear with a cup size and shape suitable for each wearer, it is easy to cut and sew, and there is little material loss, and it can be used by manufacturers, wholesalers or retailers, etc. The three-dimensional molding of the cup part can be carried out to reduce problems with inventory management and unsold items. ■Since the cup part is extruded from the inside using an extrusion mold, problems such as shine do not occur in the cup part. , etc. can be obtained.
