Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sewing machine,

The present invention relates to a non-sewn padding without a sewing line and a method of manufacturing the same, and by joining the elastic band in a state in which the cut fabric is stuck, And a method of manufacturing the same.

Socks, stockings or padding (hereinafter collectively referred to as "footwear") are used as means for protecting and maintaining feet.

Among these footwear apparel, it is made of fibers such as nylon or cotton material with stretchability, and has advantages of stretching action and ventilation effect, so that it is easily worn by the consumers in the daily life in daily life.

The padding is made by sewing a plurality of patterns wrapping around the sole, foot and heel woven with stretchable fibers, such as nylon, into a stretchable yarn, and a rubber band of rubber material is stuck around the opening in a sewing thread so as not to peel off. That is, in the conventional appendix, a plurality of pattern pieces such as a sole cover pattern, a toe cover pattern, and a heel cover pattern are sewn together and connected, or the rim of the sole cover pattern is stitched back to a pattern in which the toe and heel cover patterns are integrated The overlapping pattern portion is stitched and connected, and the stretchable rubber band, such as rubber, is stuck to the stitching chamber at the overlapping opening formed by the stitching.

Such a conventional padding may cause pain by applying pressure to the seam when the seam is worn on the foot by forming a thick seam or a convex seam on a portion where each pattern is connected by sewing and connecting each pattern, There was a problem. In addition, when the thread is stuck on the machine, it is necessary to perform the work again by disassembling and removing the stuck portion. Therefore, the manufacturing time is delayed and the process steps are troublesome, resulting in poor workability and productivity .

In order to solve these problems, Korean Patent No. 10-1314317 filed by the present applicant has a folding line which is formed by attaching a folding band which is joined in the form of wrapping the inner and outer edges of the opening, The padding can be stably attached to the foot, and the aesthetics are improved, thereby remarkably improving some disadvantages.

However, these conventional techniques still require a complicated working method because the folding band surrounds the inner and outer edges of the opening, and the width of the folding band is required to be wide, which increases the cost and increases the thickness of the opening, . Particularly, the finish parts at both ends of the left and right sides are structurally unstable, so that holes are formed when repeatedly worn, incomplete finish, uneven shapes of joints, and a foreign body, which inconveniences the user. Also, in the manufacturing method, there is a problem that overlapping portions are overlapped to form overlapping portions and then are thermally fused with hotmelt, resulting in poor workability and complicated processes.

This feature is obtained by cutting the fabric 110 and cutting it with a laser while grasping the front edge of the front lid portion 111 and the edge of the heel portion 114 and then attaching the stretchable member, So that the pad can be manufactured without sewing lines.

More specifically, after the fabric is cut as shown in FIG. 2 and the front cover part 111 is folded about the folding line 115, as shown in FIG. 3, 117, the ends of the cutouts 117 are joined to the outer ends of the cutouts 117 and separated from the outer cutouts 118. In the bonded state, the upper and lower portions are instantaneously joined together by applying heat and cutting pressure to the cutting portion 117 during the movement of the laser cutting machine accompanied by the heat. Such a joint has a certain degree of bonding force. Such a condition is referred to as "abutment" or "abutment" for convenience in the present invention.

Then, by joining the stretchable member or the strength reinforcing member in the shape of a band around the region thus cemented, it is possible to realize a strand without a sewing line.

In addition, for the sake of functionality and ease of use, the inner edge (the foot contact portion) of the front lid 111 and the upper edge (foot side contact portion) of the side portion 113 are formed by bonding elastic members as well.

If desired, the bottom portion 112 may be bonded with a band-shaped anti-slip member or silicone, and the heel portion 114 may be provided with a peel-off preventing portion 160.

The non-skid or stretchable member 120, 130, 150 may be comprised of a paper layer, a hot melt layer, and a nylon or urethane layer, which member may be in band or band form, have.

It is further preferable that the non-slip member or the elastic members 120, 130 and 150 are bonded by a hot-melt method.

By eliminating the sewing lines in this way, inconveniences caused by sewing lines in the prior art, for example incomplete finish on both sides of the front side, inconvenient touch on the wearer, and convenience in work during manufacture are provided as additional effects. In addition, since the area to be adhered is minimized according to proficiency, the wear of the fabric is small and the foreign object sensed by the wearer can be minimized.

If necessary, the non-skid member joining step (S20) may be performed to join the band-shaped non-skid member or silicon or the like to the bottom portion 112 after the step a).

The stretchable member is preferably in the form of a band or band, and more preferably a paper layer, a hot-melt layer, and a nylon or urethane layer.

In addition, it is more preferable that the bonding step is performed by a hot-melt method.

Hereinafter, the individual steps of the method for producing a seamless bar of the present invention will be described in more detail.

First, the multiposition cutting step S10 cuts the fabric 110 so as to integrally include the area consisting of the front cover part 111, the bottom part 112, the side part 113 and the heel part 114 of the lead wire. It is preferable that the cut shape has a shape corresponding to the shape that is unfolded when disposing of the reversely finished padding.

An example of such a shape is that the folding line 115 corresponds to the toe of the toe, as shown in Fig. 2, and the area 111 corresponds to the front lid. Therefore, the upper and lower regions around the folding line 115 are symmetrical. In addition, the upper end of the front cover part 111 preferably has a smoothly grooved shape to some extent, and the edge thereof is a contact area with the foot.

Similarly, the side portion 113 and the heel portion 114 are preferably formed to correspond to the corresponding regions of the finished overspring after the joining.

 Therefore, the cut shape of the fabric shown in FIG. 2 is cut in a shape that is considerably suitable for the manufacturing process of the present invention. However, when referring to the shape of the outer portion 118 that is discarded after the stitching of the present invention, But is not limited to the shape.

Then, if necessary, the non-slip member joining step (S20) may be selectively carried out. In this case, the step of joining the band-shaped non-slip member to the bottom portion 112 may be omitted if the fabric has a function of slip prevention in advance Alternatively, after the non-slip member is joined to the fabric, the cutting step S10 described above may be performed.

Next, in the attaching step S30, the area corresponding to the front cover part 111 of the lead wire is folded over the bottom part 112 with the folding line 115 as a center, and then the edge of the cover part 111 is laser- Cut.

Preferably, the fabric is cut as shown in Fig. 2, and then the front cover part 111 is folded around the folding line 115. Then, as shown in Fig. 3, the cutter part 117 is cut along the cutter part 117 using a laser cutter And the outer portion 118 separates from the end portion of the cut portion 117. Fig. At this time, the edge of the cut portion 117 is joined by heat and pressure of the cutting machine.

Next, in the elastic member 120 joining step (S40), the edge of the cut front lid part 111, that is, the cut part 117, is bonded to the stretchable member 120 in a band-shaped manner, preferably by a hot-melt method.

Subsequently, similarly, the edges of the front cover portion 111 and the side portion 113 are joined to each other by the stretchable member 130 in the form of a band (S50).

Then, in the heel attaching step S60, both ends of the side portion 113 to which the stretchable member 130 is joined are folded inward, and the both ends are aligned (in this case, the ends may finely overlap) The edge 140 of the heel portion 114 is cut out from the outer side with a laser, and is stuck. The technical principle for this is the same as the above-described stitching step S30.

Then, in step S70, the abutment portion 140 of the cut heel portion 114 is joined to the stretchable member 150 in the inside or outside of the belt-shaped stretchable member 150 (S70).

The use of such elastic members 120, 130, and 150 can impart functionality while maintaining elasticity so that the wearer's body does not have a sense of resistance while reinforcing the strength of the crotch region.

Finally, the peeling can be manufactured in a simple manner by applying or attaching silicon to the inside of the upper end of the heel portion 114 to form the peeling prevention portion 160 (S80).

In addition, the manufacturing method of the present invention has an advantage that it is possible to prevent defects that may have been generated through the sewing work through the manufacture of the padding without separately sewing.
