Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is beautiful when two side panel fabrics made of an elastic mat such as a spring mattress and a urethane mattress and two side border fabrics are combined and wrapped with an edge tape for sewing. The present invention relates to a uniform, reliable, and easy sewing method.

[0002]

2. Description of the Related Art Double-sided panel fabrics and side border fabrics of elastic mats (hereinafter simply referred to as mattresses) such as spring mattresses and urethane mattresses have been conventionally cut to the required size according to the mattress dimensions. In this case, each end is inserted into a binder (sewing auxiliary tool) into which an edge tape has been introduced just by performing "overlock stitching" or "fold-back stitching" to perform sewing.

Since the mattress uses springs, urethane, etc. for the interior material, the repulsive force is strong and the surface panel material and the side border material are pulled to the center.
Therefore, when wrapping and sewn with the edge tape, the edge tape provided at the sewn portion of the sewing tape edge sewing machine (not shown) is introduced, and the end portions of both cloths are inserted into the binder insertion opening by the operator. Was pulling with a considerable force, and was sewing intermittently while aligning.

The work described in the preceding paragraph requires a high degree of skill and requires the force of the fingertips of the worker, and the operator is very tired and it is difficult to continue the work for a long time.

[0005]

The problems associated with the prior art will be described in detail with reference to the drawings. FIG. 6 is a state diagram in which both fabrics (1) and (2) are normally wrapped by the edge tape (3) and sewn by the edge tape (3).

In FIG. 7, the panel material (1) is inserted normally, but the side border material (2) is pulled downward by the repulsive force of the spring urethane installed due to insufficient pulling force of the operator. As a result, both ends are uneven, and as a result, the wrapping of the edge tape (3) becomes uneven,
As a result, the mountain shape of the top portion wrapped with the edge tape (3) collapses, and the edge tape (3) bends and deforms toward the panel material (1) side.

In this case, the most troublesome thing is that the sewing thread (4) is attached to the end portion of the side border cloth (2),
There is a risk that the end of the side border material (2) may be slit due to the repulsive force of the interior material, and the side border material (2) may come off the sewing thread (4) and "puncture".

FIG. 8 shows the case where the panel material (1) is pulled toward the center, which is the opposite of the previous item, and the opposite result occurs similarly to the previous item.

When sewn in the state shown in FIG. 7, the result is the same as when the border material (2) is stretched, and it is pulled toward the center of the panel material (1), so that the sewn edge tape ( 3) bends to the state shown in 3-A of FIG.

Further, when sewn in the state shown in FIG. 8, the same result as when the panel material (1) is stretched is obtained, and since the border material (2) is pulled downward, the sewn edge tape is obtained. (3) bends to the state shown by 3-B in FIG.

The above-mentioned state should be a straight line state as shown by 3-C in FIG.
Further, even if the conventional best condition shown in FIG. 5 is sewn, the edge tape (3) has a small roundness and is easily fallen down. Therefore, the sewn edge tape (3) has a meandering appearance. And the appearance that is the life of the mattress is completely lost, so the commercial value is reduced.

In addition to the above, the above-mentioned condition is for both fabrics (1)
Since the end of (2) is not completely sewn with the edge tape (3) and the sewing thread (4), these mattresses cannot withstand long-term use and become "punctured". There was an issue.

Further, the finish appearance inspection of the mattress is emphasized, and if a defect is found, it will affect the appearance problem and the service life. Therefore, a skilled worker will loosen the sewing thread (4) and I wasted a lot of time, such as carefully re-correcting it so as not to spoil the aesthetics of.

Further, as described above, the mattress panel fabrics (1) and (1 ') and the side border fabrics (2) are pulled toward the center by the repulsive force of the interior material, so the worker always arranges both fabrics. Since a considerable amount of force was required to draw the ends of the toe and align them, fatigue was high and it was difficult to work for a long time.

Further, a skilled person is required to perform accurate sewing, and even the skilled person has to carry out a "single step" work in which the end portions of both fabrics are drawn together and aligned, and therefore the productivity is low. was there.

[0016]

In order to solve the above-mentioned various problems, the present invention was conducted as a result of various researches and experiments, and after cutting a double-sided panel material and a side border material into required dimensions in accordance with conventional specifications, Abolishing "overlock stitching" or "folded back stitching" of the ends of both fabrics that has been conventionally performed, and instead of the present invention, the present invention is applied to the four peripheral ends of both panel fabrics and also to the side border fabrics. For both ends, select "string", "thick yarn", "thin rope" (hereinafter referred to as "core string"), etc., which is an interlining suitable for the size of mattress, material and type of cloth, A piping portion having an interlining is formed at the end of the fabric by any one of "overlock stitching", "roll-in stitching", "welding", and "adhesion with an adhesive".

The tip end of the binder into which the edge tape has been introduced, the end of the panel material and the side border material that have been piped into the insertion port (piping section) are inserted, and the sewing machine sewing section of the piping in which the edge tape has been introduced. Before and after, the piping guide is arranged symmetrically, and the piping guide is arranged so that the piping portion is sufficiently guided.

Therefore, since the ends of the panel material and the side border material, that is, the piping portion, are fed and sewn at the tip of the binder along the piping guide, "deviation" occurs.
"Peeling" is completely prevented. In addition, the edge tape is sewn up inside, and the effect of piping ensures a rounded shape with a chevron shape, and the straight portion has a stable shape without bending.

Further, the curved portions at the four corners of the mattress are also ensured to have a uniform and ideal shape.

[0020]

Next, the operation will be described with reference to the drawings. Figures 3 and 4
・ 5 is "overlocking" a core string (5) at the ends of the double-sided panel materials (1) and (1 ') and the side border material (2),
Alternatively, the drawing shows a state in which the piping portion (6) is formed by "winding and sewing".

A spring, urethane, or the like (not shown) is provided inside the panel material (1) / (1 ') and the side border material (2) in which the piping portion (6) is formed by any one of the above-mentioned methods. Once inside, insert the piping parts (6) of both cloths (1) and (2) into the binder (8) tip end insertion opening into which the edge tape (3) is inserted, as shown in FIGS. Piping guides (9) and (9 ') are arranged on both sides of the binder (8) before the sewn portion.

The piping portions (6) of both the cloths (1) and (2) are formed, and the ends of the cloths are sewing machines (not shown).
The edge tape (3) is sewn by the sewing machine while being regulated and moved by the piping guides (9) and (9 ′) at the tip of the binder (8) according to the feeding and movement of the binder and wrapped by the edge tape (3). Is regulated by the binder (8) and does not come off from the piping section (6).

Further, since the piping portions (6) of both the materials to be sewn are completely regulated by the piping guides (9) and (9 '), they have a certain rounded shape until the end of sewing. A stable and stable edge tape (3) can be sewn on.

[0024]

An embodiment of the present invention will be described in detail with reference to the drawings. Corresponding to the shape and size of the mattress, the material and type of the fabric, the four sides of the double-sided panel fabric (1) and (1 ') cut into the required dimensions, and the core string on both ends of the side border fabric (2) The method of sewing (5) will be described below.

FIG. 3 shows a state in which a piping portion (6) is formed by "overlocking" a core string (5) by using an overlock sewing machine at the ends of the both materials and sewing them.

In FIG. 4, the core string (5) is "overlocked" and sewn to the upper surface or the lower surface of the end portions of both cloths by using the overlock sewing machine as in the previous item, and the piping portion (6).
The state in which the is formed is shown.

FIG. 5 shows a state in which the core string (5) is wound around the ends of both materials and is sewn with a lock stitch sewing machine or a chain stitch sewing machine to form the piping portion (6).

As described above, by attaching an auxiliary tool for introducing the core string (5) to a sewing machine similar to the "overlock stitching" or the "fold-back stitching" which has been conventionally performed, Easy to implement.

Further, the material of the core string (5) is adapted to the shape and size of the mattress and the kind of material of the cloth,
It is possible to freely select "cord", "thick count thread", "thin rope", etc. according to the material and the sewing method, and to adjust the diameter of each core string (5).

Further, the piping portion (6) may be formed by "welding", "adhesion by an adhesive" or the like other than sewing by sewing machine.

Next, as shown in FIGS. 1 and 2, the edge tape (3)
One of both panel cloths (1) and (1 ') in which the piping portion (6) of both cloths is formed at the tip of the binder (8) in which is introduced, and the end of the side border cloth (2) are connected to the binder. Insert it into the tip end insertion port of (8), and place the piping guides (9) and (9 ') near the sewing part of the binder (8).
Are symmetrically arranged at the tip of the binder.

Both piping portions (6) are completely regulated by piping guides (9) and (9 ') arranged near the insertion openings of both piping portions (6) at the tip of the binder (8). Since the mattress that is sewn with the edge tape (3) has an internal spring and urethane incorporated therein and has a repulsive force, the edges of both fabrics (1) and (2) are edge tape. It does not come off from the binder (8) in which (3) is introduced, and both piping parts (6) are wrapped in the edge tape (3) by the feeding and moving of the sewing machine, while the above-mentioned piping guide (9) It moves along with (9 ') and is sewn together with the edge tape (3).

For this reason, the conventional method frequently occurs,
The unevenness of the ends of both panel materials (1) or (1 ') and the side border material (2) is completely eliminated, and the edge tape (3) after sewing is fixed by the two piping parts (6), especially the straight part. 3-C is completely possible in a straight line with a rounded chevron shape.

Also, the curved portions at the four corners of the mattress are provided with the piping guide (6) and the piping guide (9).
A uniform shape is secured because sewing is performed while guiding at (9 ').

Even if a tape-edge type sewing machine for sewing the mattress edge tape (3) that has been conventionally used or a mattress moving type sewing machine is used, no special modification is required, and the conventional "overlock" Similar to "sewn" and "folded back stitching", the sewing of the edge tape (3) is possible even for beginners without needing a skilled person just by forming the piping part (6) simply by sewing the core string (5) of any material. The hem tape (3) can be sewn on.

[0036]

As described above, according to the present invention, the end portions of the respective fabrics forming the mattress have been "over-sewn",
Or, instead of the process of "sew back folding", interlining materials such as "core string", "thick count thread", "thin rope", which are materials that are suitable for mattress fabric, are attached to the end of each fabric.
It is only necessary to form the attachment piping portion by "overlock stitching" or "roll-in stitching", and the sewing method can be carried out by an automatic machine using various auxiliary introduction tools known in the art.

By inserting the end portion of the fabric of the mattress in which the piping portion is formed into the insertion opening of the tip portion of the binder into which the edge tape is introduced, and by arranging the piping guides symmetrically on both sides, the piping portion is formed. Is completely regulated by each piping guide, and is sewn while being wrapped with edge tape by the drive of the sewing machine. For this reason, the "collapse" of the wrapping shape of the edge tape due to incomplete wrapping of the edge tape due to "misalignment" at both ends and "unevenness", which has been a serious problem from the past, is completely prevented, and As for the effect of piping, it is possible to provide a finished product that is beautiful and has high commercial value because it has a rounded mountain shape and an ideal fixed shape is secured.

Further, when the wrapping sewing of the end portions of both fabrics by the edge tape is incomplete by the experience of the expert and the final finish inspection by "intuition" which has been a problem in the past, the sewing thread at that portion is incomplete. Careful, time-consuming re-modifications were carried out so as not to unravel and damage the appearance of the mattress, but the provision of the method of the invention makes it possible to prevent this completely.

Therefore, even if a beginner does not rely on the "intuition" of a skilled person, even if a beginner just inserts the end piping portions of both fabrics into the insertion opening of the binder, the piping guide can completely insert the edges. Since it is regulated, the edge tape piping portion is wrapped and it is possible to sew securely, uniformly, comfortably and quickly.

Further, since the above effects do not require a skilled worker and even beginners can work, the work efficiency cannot be compared because the conventional "single step" intermittent sewing method is abolished. It is certain that it will improve.

By the provision of the present invention, the sewing work of the edge tape, which is the most difficult and the most problematic in the mattress manufacturing process, can be automated, and the effect of the provision of the present invention is remarkable.
