Abstract

PURPOSE: To improve wiping at the time of hanging, and also to reduce the extension in the hanging allowance by performing an auxiliary sewing at the toe part of an instep cover. CONSTITUTION: Cotton cloth being used in a front cloth is used for the material of an instep cover 1, and the cloth in which nylon tricot has been stuck on urethane foam is used for a rear cloth. The front cloth and the rear cloth are stuck by welding, and are cut into the respective parts of the shapes of the instep cover 1, and a front core 8 is stuck on a cut front instep 7 and also a heel reinforcement is sewn on the waist. After these front instep 7 and the waist have been sewn, to prevent the turn-up of urethane foam, the entire circumference of the front instep is sewn at a sewing allowance of 2mm. Then, an elliptical or semicircular auxiliary sewing 5 is performed by using a vinylon thread in the extend of 30 to 40mm right and left from the hanging allowance 4 making a center of a foremost center 3 of a toe part 2. The hanging is completed by fitting the instep cover 1 on a last 9, and by squeezing it while pressedly bringing the hanging allowance of the instep cover 1 into contact with the last by means of a bed laster.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an instep that facilitates hanging of the instep of hand-applied shoes, especially children's shoes.

[0002]

2. Description of the Related Art Conventionally, the work of suspending the instep of a hand-applied shoe on the last is manually carried out by a hook, which is a suspending tool. Recently, a semi-automatic suspender or a fully automatic suspender is often used in consideration of labor shortage, working environment, work efficiency, and the like.

[0003]

With these machines, when suspending the instep on the last, it is necessary to prepare the machine for different conditions such as the shape of the last and the thickness of the instep. In particular, the preparation of the blade edge called the wiper that presses the instep cover against the last, which is the most important, requires delicate preparation and requires an experienced veteran operator. In particular, for the purpose of protecting the feet of children's shoes, a last having a wide toe shape is used. When the instep cover is hung by a semi-automatic suspender such as a bed raster using the last, the wiper for narrowing down the periphery of the instep does not hang easily, and a condition is said to be swollen. Furthermore, depending on the material of the instep, this hanging up is likely to occur because the hanging allowance extends when narrowing down. Further, when cutting dough into the shape of the instep, several dozen pieces of cloth are cut by the blade die, so that some of the pieces are inevitably cut larger than the initial size due to the cutting of the blade die.

When the above instep cover is used, an excessive lifting margin is likely to cause an excessive rising condition. If the bottom and the tape are stuck on the bulging state caused by the rise, the appearance is bad and the unevenness causes unevenness to cause the bottom to separate. Children's shoes, women's shoes, etc. that give a soft, soft and voluminous feel,
Since the material with such a texture is used as the material for the instep, the elongation when hanging is remarkable. The present invention has been made for the purpose of solving these problems.

[0005]

[Means for Solving the Problems] After cutting a laminated cloth for instep into the shape of the instep, and after adhering or sewing a toecap or a tip cloth, the hanging margin is applied from the tip center of the toe part of the instep. Auxiliary sewing is performed with two needles (needle width 2.5 to 3.5 M / M) in the shape of an ellipse or a half moon from the width of the width to the left and right about 30 to 40 M / M (depending on the size).

[0006]

By the auxiliary sewing of the toe of the instep, the wiper can be easily hooked when hanging, and the extension of the hanging allowance can be reduced.

[0007]

EXAMPLES Examples of the present invention will be described in detail below. Although the practice of the invention is described in practice in children's shoes, it is currently used in many varieties. As the material for the instep (1), a cotton cloth that is generally used for the front cloth is used, and for the back cloth, a cloth in which nylon tricot is attached to urethane foam is used. The front and back fabrics are pasted together by heat welding, cut into each instep (1) shaped part, the toecap (7) is adhesively attached to the cut instep (7), and the heel reinforcement is sewn on the waist. To do. After sewing the front instep (7) and the waist, the entire peripheral edge is sewn at a seam allowance of 2M / M in order to prevent the urethane foam from curling.

After that, from the center (3) of the tip of the toe portion (2) of the present invention to the left and right from the distance of the hanging margin (4), 30-40.
Approximately M / M (depending on size), using # 30 vinylon thread, elliptical or semi-lunar 2 needles (needle width 2.5-3.5M
/ M) to perform auxiliary sewing (5). In this implementation
Although 30 vinylon yarns were used, it is not limited to this. The sewing shape of the auxiliary sewing (5), the number of sewing threads, and the distance between the two needles have been described above, but are not limited thereto.

The upper cover (1) is attached to the last (9), and the hanging cost of the upper cover (1) is squeezed with the bed raster (name of the suspending machine) while being pressed against the last. Complete. On the other hand, for the shoe sole, a design roll in a separate process is used to apply the design to the ground contact surface, and then the shoe sole is cut into a shoe sole shape. The shoe sole is adhered to the public expense for completing the suspension, and then the lower peripheral tape is adhered to manufacture the shoe.

[0010]

[Effect] The effect of the present invention is that the toe of the instep cover is sewn auxiliary to the wiper so that the hanging of the wiper is improved and the extension of the hanging margin is reduced. Therefore, it becomes possible to prevent the swelling of the false. Also, because there is no unevenness due to rising, adhesion is sufficiently performed and the adhesive strength increases,
The appearance is also beautifully finished. It also has the effect of reducing the occurrence of defects and improving consumers' willingness to purchase, especially children. Further, when suspended by a semi-automatic machine, it is almost unnecessary to prepare a cutting edge called a wiper for different conditions such as the shape of the last and the thickness of the instep cover. Therefore, even an inexperienced person or a woman can perform the work without being a skilled and experienced worker. In this way, not only the product value but also the productivity is improved and the economic effect is great.
