5 is a plan view of the elastic band bonding configuration according to the present invention.

The present invention will now be described in detail with reference to the accompanying drawings.

A specific technical structure for solving the problem of the circular elastic band produced by the heat fusion bonding method is as follows.

A circular elastic band manufactured by a heat fusion method is an elastic band 100 which comprises a band of elastic resin 110 and forms a fiber sheath 120 with the covering of a fibrous material,

The heat fusion portion 200 is formed by a thermal fusion bonding method and is cut around the cutting line 300 and the joined portions 310 of the cut portions are bonded to each other with the adhesive 330 to form a circular elastic band The present invention is characterized in that,

As shown in Figure 1,

The elastic band 100 is formed of a string-shaped elastic band 100 by having a band of elastic resin 110 inside the fiber shell 120.

The fiber envelope 120 of the elastic band 100 is composed of a blend yarn or a synthetic resin yarn and is formed by a biased circular knitting process to form a fiber envelope 120,

The elastic resin 110 is formed of a string having an elastic body made of a rubber material, a urethane, and a PU material.

As shown in Figure 2,

And a step of thermally fusing a predetermined area around the cutting line 300 as a cutting position of the elastic band 100 to form the thermally fused portion 200.

The heat fusion of the heat fusion portion 200 is formed by a high-

The thermal fusion is performed by using a bias circular knit method to prevent the fiber sheath 120 from being unwound after the fiber sheath 120 is cut and to prevent the elastic bands 100 from being cut when the fiber sheath 120 and the elastic resin 110 are bonded together The joining surfaces 310 of the elastic bands 100 are uniformly joined to each other when the both ends of the elastic bands 100 are joined to each other so that the joining surfaces 310 of the elastic members 110 coincide with each other .

As shown in FIG. As such,

And cutting the cut line (300) at the cutting position of the elastic band (100) formed with the heat fusion portion (200) with a cutter,

The elastic bands 100 formed in the form of long strings are formed by continuously forming the thermally fused portions 200 at intervals of a predetermined length and the center of the thermally fused portion 200 is cut with a cutter, The elastic band 100 is formed of a certain length.

As shown in Figs. 4 and 5,

A circular elastic band 100 is formed by bonding an adhesive to the joint surfaces of both ends of the elastic band 100 cut to have a predetermined length,

And a decorative or decorative part is inserted or joined before the circular elastic band 100 is formed to improve decorative property and bonding property.

It is a feature that the elastic band 100 having the above-described structure is formed into a function of a circular elastic band 100 by forming and cutting a heat fusion portion 200 and bonding the cut bonding surfaces 310 with an adhesive .

According to another aspect of the present invention,

As shown in Figure 2,

The forming of the heat-welded portion 200 is performed by fusion bonding between the direct irradiation of the fiber sheath 120 and the fusion of the elastic sheath 120 and the elastic resin 110 by a high- ,

Even if cut, the fiber sheath 120 is not loosened,

And the joint surfaces 310 formed by cutting the fiber sheath 120 and the elastic resin 110 coincide with each other to be grounded and joined together with the adhesive 330 when they are joined together.
