Technical Field [0001] The present invention relates to an elastic band sewing method using a fabric fixing device,

The present invention relates to a method of sewing elastic bands using a fabric fastening mechanism and to a sewn fabric for imparting elasticity to the fabric.

An elastic band such as an elastic band is sewn so that the elastic band is not detached from the fabric at the portion where stretching is required for the convenience of the user to wear, such as the sleeve portion on the lower side, the waist portion or the ankle portion on the lower side.

Conventionally, in the elastic band sewing operation, the operator stretches the elastic band in one direction and sews the elastic band in a state in which the fabric is stretched. Therefore, the operation is troublesome, laborious and time consuming. Further, there has been a problem in that the tension of the elastic band is not uniformly maintained at the time of sewing, or the elastic band is often sewn in a state in which the elastic band is warped to one side, and the sewed elastic band is not properly stretched or the appearance is not good.

Fig. 1 is a perspective view of a fabric fixing apparatus 100 for sewing elastic bands according to an embodiment of the present invention, and Fig. 2 is a side view of Fig. 1. Fig. Referring to FIGS. 1 and 2, a fabric fixing apparatus 100 for sewing elastic bands is provided with a mounting frame 10 provided at the center thereof with an opening 10a interposed therebetween, a fixing frame 10 connecting adjacent opposite ends of the mounting frame 10, (20).

As described later, the seat frame 10 is a portion where a fabric with an elastic band is seated and sewing work is performed. The seat frame 10 is composed of a pair of horizontal frames arranged vertically and extending in parallel to each other in the longitudinal direction, and an opening 10a in which elastic bands having both ends fixed to the fabric are disposed are formed in the center.

On the surface of the seat frame 10, a length display portion 11 is formed. The length display portion 11 is a scale or a number provided to indicate the length between both ends of the fixed frame 20 to which the fabric is fixed. The operator can adjust the interval between the fixed frames 20 in accordance with the length of the fabric to be stretched according to the size or material of the elastic band.

The stationary frame 20 is a portion to which a fabric extending in one direction is fixed by an elastic band. The stationary frame 20 is formed of a pair of vertical frames connecting the upper and lower ends of the seat frame 10 in an upward direction and an entrance 20a communicating with the opening 10a is formed at a lower portion thereof. The fabric to which the elastic band is attached enters and exits the opening 10a through the entrance 20a.

The fixed frame 20 is movably coupled in the longitudinal direction of the seat frame 20 to be fixed to the stretched fabric length, as described above. Referring to FIG. 1, the fixed frame 20 provided on the right side is slid on the seating frame 10 to adjust the gap with the fixed frame 20 fixed to the left side. There is provided a fixing screw 21 which is fastened to a fastening hole formed through the fastening frame 10 and the seat frame 20 in order to fix the fastening frame 20 slidably moved on the seat frame 10. [

In the upper part of the fixed frame 20, fixing means for fixing the fabric to be restored by the elasticity of the elastic band is provided. In FIG. 1, the fixing pin 22 is shown as fixing means. The fixed clamp 22 is coupled to the upper portion of the fixed frame 20 to fix the fabric. It is preferable that the uneven surface 23 is formed on the fixed frame 20 in order to improve the fixing force of the fabric by the fixed clamp 22. The uneven surface 23 continuously forms the grooves and the protrusions by surface-processing the fixed frame 20, so that no slip occurs on the surface when the fabric is fixed.

FIG. 3 is a perspective view of a fabric fixing apparatus 200 for sewing elastic bands according to another embodiment of the present invention. In FIG. 3, a toggle clamp 24 is provided on a seat frame 20 as cloth fixing means. The toggle clamp 24 includes a pressure plate 25 whose one end is pivotally coupled and pivoted up and down, and a lever 26 which pivots the pressure plate 25 up and down. The presser plate 25 is vertically rotated by the operation of the lever 26 to fix the fabric. The presser plate 25 is provided under the presser plate 25 with a support plate 27 extending from the support frame 20, (27). Other fixing means other than the above-described fixing clamp 23 or the toggle clamp 24 may be used, for example, a Velcro tape or an adhesive may be used.

Although the seating frame 10 is described as a horizontal frame and the stationary frame 20 as a vertical frame in the above embodiment, the stationary frame 20 can be realized as a horizontal frame with the stationary frame 10 as a vertical frame Of course.

Hereinafter, an elastic band sewing method using the above-described fabric fixing apparatus for sewing elastic bands will be described. The procedure of the sewing method according to the present invention is shown in FIG. 4. First, one end of the elastic band is fixed to a fabric and then stretched in one direction to fix the other end to the fabric (S110). FIG. 5 is a view showing an operation in which both ends 31 and 32 of the elastic band 30 are fixed. In this step, the elastic band 30 can be unidirectionally stretched. The fixing method is usually sewn in a thread, but it may be fixed by an adhesive or a sticker in some cases. This procedure is illustrated in FIGS. 6 and 7, which then attach the fabric to the fabric fastener 100. The cloth fixing device 100 is installed on the work table S120 and then the fabric 40 is exposed so that the elastic band 30 is exposed to the opening 10a through the entrance 10b formed on both sides of the cloth fixing device 100 (S130). 6 (a) and 6 (b), after one end 41 of the fabric is fixed to the one fixing frame 20 of the fabric fixing mechanism 100, the fixing frame 20 is fixed to the mounting frame 100, The other end 42 of the fabric is fixed to the other fixing frame 20 of the fabric fixing mechanism 100 (S140). The fabric 40 is firmly fixed by the uneven surface 22 of the fixed frame 20 to be contacted. 7 (a) and 7 (b), the fixing frame 20 is moved so that the elastic bands 30 come into close contact with the fabric 40 without wrinkles or bending, After stretching in one direction, the fixing frame 20 is fixed with the fixing screw 21 (S150). Therefore, as the fabric ends 41 and 42 are fixed to the fixed frame 20, a uniform tensile force acts on the elastic band 30. [ According to the present invention, the elastic band 30 can be realized in various shapes, sizes, quantity, and materials in accordance with the use and characteristics of the fabric. In accordance with the present invention, The fabric 40 can be fixed by moving it in the longitudinal direction of the seat frame 10. On the other hand, when the toggle clamp 24 described above is used as the fixing means, the fabric is fixed between the pressure plate 25 and the support plate 27 by the operation of the lever 26. [ When both ends 41 and 42 of the fabric are fixed, the elastic band 30 exposed in the opening 10a is sewed using the sewing machine 50 as shown in FIGS. 8 and 9 (S160). Fig. 8 is a view showing an operation of sewing the elastic band 30 having a relatively narrow width in the longitudinal direction, and Fig. 9 is a view showing an operation of sewing the elastic band 30 having a relatively wide width in the width direction.

On the other hand, the reinforcing fabric 50 shown in Fig. 10 can be used when the fabric 40 is fixed. The reinforcing fabric 50 is a fabric that is pegged to the fabric 40 and secured to the fixed frame 20 and may be formed by sewing a fabric 40 having an elastic band 30 attached to the end close to the end as shown in Fig. Is used to protect the fixing portion of the elastic band 30 which is fixed imperfectly by damage of the fabric portion fixed to the fixed frame 20 or unidirectional stretching of the fabric.

According to the present invention, since both ends of the stretched fabric 41 and 42 are fixed to the fabric fixing mechanism 100, the operator does not need to separately work to stretch and fix the elastic band 30, thereby improving workability . In addition, since uniform tension is applied to the elastic band 30 by the fabric fixing mechanism 100, the elastic band 30 can be arranged flat on the opening 10a without bending, and stable sewing work can be performed The fixed frame 20 can be moved in the longitudinal direction and adjusted to fit the extension length of the elastic band 30.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents.
