Brass cup support bag forming method

The invention relates to a method for forming a bra cup support bag, in particular, after a support bag is formed, a different cup wire strip or a plastic cup support strip can be selected afterwards, and the wire rod or plastic in the support bag can be extracted at any time as needed. The support bar is not user.

At present, the bra is made of cloth, and then a foam or an upright cotton cup is placed on the breast. The foam or the upright cotton cup is made of thermoplastic, which is supported by the protruding shape of the breast, and the entire corset is foamed or The upright cotton cup is hot moldable, and there are two methods for setting the cup wire strip or the plastic strip cup support strip under the breast cup.

The utility model relates to a cloth arranged on a corset, which is used for setting a bottom edge of a cup, and adopts a sewing method to manufacture a curved long bag, and then placing the wire strip of the cup into a closed long bag. The mouth is used to position the wire rod of the cup, which is costly, and the wire of the cup is curved. When the sewing is fixed, the cloth may wrinkle and become unsmooth.

The other one is set in a thermoplastic foam or an upright cotton cup. The protruding shape of the breast formed by the cup is heated by a chest-shaped mold, and the two flat foams or the upright cotton are heated by the mold. Pressing, the breast shape cup is formed, and the wire rod is placed between two flat foam or erect cotton, and then the two flat foam or upright cotton is adhered by the mold during heating and pressing, and the steel wire is simultaneously made The strip is covered with a limit.

In the past, the corsets were provided with metal cup wire strips under the cups at the breasts. The corsets or cups must be inspected by the customs when they are exported. The quarantine time will become the case when the bras or cups are covered with metal. Very long and troublesome, it is necessary to avoid the problem of long-term troubles in customs quarantine. Some people also replace the wire rod with a non-metallic plastic support strip material to speed up the customs inspection. However, the metal and plastic materials are very characteristic. Different, thin metal has excellent support and flexibility, not all customers can agree with plastic support strips.

Therefore, how to design metal cup wire rods can be placed in hot plastic foam or upright cotton cups, and it can be easily and quickly passed through customs inspection, and even can be replaced at any time according to the user's preference or choose not to use steel wire support bars or Plastic support strips are the focus of improvement.

It is known that the bra neck cup wire support belt is integrated into the cup when it is formed, and is formed and covered in the cup. The cup is subjected to customs inspection at the exit, because the corset or the cup is covered with metal. The quarantine time will become very long and troublesome. In order to pass the customs inspection quickly, and you can change or choose not to use the steel support strip or the plastic support strip at any time according to the user's preference, it is the focus of improvement.

The method for forming a bra cup support bag according to the present invention comprises: A. using an inner cup layer and an outer cup layer and a molding strip, the inner cup layer comprising: a table cloth 11 and a first thermoplastically moldable layer, The outer cup layer comprises: a second thermoplastically moldable layer and a lining strip, wherein the forming strip is an arc-shaped strip, and the first thermoplastically moldable layer and the second thermoplastically moldable layer are foam or erect fiber cotton, etc. A material that deforms when heated and cools and can be shaped. B. The inner cup layer and the outer cup layer are correspondingly overlapped by a first thermoplastic moldable layer and a second thermoplastic moldable layer, and the formed strip is disposed on the first Between a thermoformable forming layer and the second thermoplastic formable layer, and one end of the forming strip is wrapped in the first thermoplastic moldable layer and the second thermoplastic moldable layer, and the other end extends out of the inner cup layer and The outer layer of the outer cup is an extended section. C. Using a cup forming mold, the cup forming mold comprises an upper mold 41 and a lower mold, wherein the upper mold 41 and the lower mold are provided with a breast-shaped male and female mold hole and a side of the male and female mold holes. The male and female support pockets. D. The inner cup layer and the outer cup layer are disposed between the upper and lower mold cavities of the upper mold and the lower mold of the cup forming mold, and the forming strip is disposed on the first thermoplastic moldable layer and the second heat The plastic forming layers are located between the male and female support pockets, heating the cup forming mold, and pressing the inner cup layer and the outer cup layer to form a thermosetting bond. E. The cup forming mold is opened to form a cup semi-finished product having a cup portion and a curved strip-shaped supporting bag. At this time, the forming strip is located in the supporting bag, and the protruding portion protrudes out of the supporting bag. F. Using the protruding section of the forming strip, the forming strip is pulled away from the support bag, the support bag is hollow formed, and an opening is formed on one side. G. Cut the semi-finished product of the cup to the periphery to remove unnecessary parts and become the finished cup. H. Using a support strip to penetrate into the support bag, forming a cup with a support strip, and supporting the support strip on the bottom edge of the support bag, the support strip is made of steel wire or plastic steel, and the section of the formed strip The cross section of the support strip is larger than that, so that the support strip can be smoothly inserted into the support bag afterwards, and the depth of the support bag is greater than the length of the support strip. I. After the support strip penetrates into the support bag, the opening of the support bag is closed. J. Finish the finished product.

The invention can form an open support bag at the lower position of the breast-like shape of the finished cup product, and the support bag can be inserted into the support bar at any time point or any other processing procedure, because the metal cup is not disposed first after the cup is formed. The support bar can quickly pass the customs inspection when the export passes the customs inspection, and can be replaced at any time according to the user's preference or choose not to use the steel support bar or the plastic material support bar.
