Definitions
- the present invention relates to a sewn product and a sewing method of material, and particularly relates to a sewn product in which material edges having different thickness, for example, an edge of a fastener tape and an edge of a main material are stitched together and a sewing method for producing the same.
- the main material is overlapped on one surface of the fastener tape at an edge-side of the tape in the width direction, and then the fastener tape and the main material are stitched in plain seam. Subsequently, the main material is folded back, and then, the fastener tape and the main material are further stitched together. Generally, the main material is also overlapped on the other surface of the fastener tape and then stitched with the tape in plain seem. After that, the main material is folded back, and then the fastener tape and the main material are further stitched together. Thus, the stitched portions are thick and hard.
- both of the fastener tape and the main material are necessary to have larger sizes for that.
- the width of the fastener tape is required to have five to six times of the width that is occupied by its elements. Accordingly, both material costs for the fastener tape and the main material are high.
- the material edges are stitched together with six threads, so that the thickness of the stitched portion is increased by thicknesses of the threads, and the stitched portion is conspicuous due to its long width.
- the sewn width of the stitched portion is raised widely so as to cause a bumpy texture, and the sewing holes appear complicated, which may be a damage for the design.
- stopping force against a lateral load is so weak that a gap is generated between the materials, and thus, superimposed seam is mainly adopted for such stitching and materials-abutted seam is rarely used.
- Patent document 2 discloses a technique for solving the above-mentioned problems in the sewing method using the flat seamer sewing machine.
- the Patent document 2 fails to disclose solving a specific technical problem which is caused when sewing the materials with different thicknesses in materials-abutted seam.
- the inventors of the present invention have found a problem that, in a case where an edge of a fastener tape and an edge of a main material are stitched together in an abutted state by using this technique, the fastener tape is finished waving in its longitudinal direction.
- an object of the present invention is to provide a sewn product in which material edges are stitched together and a sewing method for producing the same, in which a thickness, a bumpy texture, hardness of a stitched portion of two materials with different thicknesses, such as a fastener tape and a main material, would be reduced; the stitched portion would be less noticeable and finished to be simpler; and the strength of the stitched portion may be ensured.
- Another object of the present invention is to provide a sewn product and a sewing method of material, which would save material costs and simplify sewing processes.
- Still another object of the present invention is to provide a sewing method of material, which may reduce or prevent waving of a fastener tape.
- a sewn product in which an edge of a first material and an edge of a second material that is thicker than the first material are stitched together in an abutted state, wherein the edge of the first material and the edge of the second material are stitched together with one bobbin thread and a plurality of needle threads, the plurality of needle threads being interlocked with the one bobbin thread to form a plurality of rows of zigzag stitched seams.
- two rows of zigzag stitched seams may be formed by two needle threads, and wherein the edge of the first material may be overedge-stitched by one of the two needle threads and the bobbin thread, and the edge of the second material may be overedge-stitched by the other of the two needle threads and the bobbin thread.
- three rows of zigzag stitched seams may be formed by three needle threads.
- One of the three needle threads may be stitched alternately to the edge of the first material and the edge of the second material.
- the other two of the three needle threads may be stitched to the edge of the first material or the edge of the second material at both sides of the one needle thread.
- the first material may be a fastener tape to which elements are attached.
- a length of the fastener tape in a width direction may be twice to four times of a length of the elements in the width direction (see “E” in FIG. 9 ).
- a length of the fastener tape in its width direction is required to be larger for that accordingly.
- the length of the fastener tape in the width direction is required to be five to six times of the width of the elements.
- a sewing method of material in which an edge of a first material and an edge of a second material that is thicker than the first material are stitched together in an abutted state, wherein the edge of the first material and the edge of the second material are stitched together with one bobbin thread and a plurality of needle threads, the plurality of the needle threads being interlocked with the one bobbin thread to form a plurality of rows of zigzag stitched seams.
- the edge of the first material and the edge of the second material may be stitched together with using a sewing machine which includes a vertical full rotation shuttle and a plurality of sewing needles, wherein the plurality of sewing needles are arranged in a direction perpendicular to a feed direction of the first and second materials and sway in the direction perpendicular to the feed direction.
- the first material and the second material may be respectively fed with feed dogs that are set at different feed rates, while the first and second materials are pressed at an equal pressure.
- the feed rate of the feed dog for feeding the second material may be set to be higher than the feed rate of the feed dog for feeding the first material.
- the first material may be a fastener tape to which elements are attached.
- a length of the fastener tape in a width direction may be twice to four times of a length of the elements in the width direction.
- the present invention provides a sewn product in which material edges are stitched together and a sewing method for producing the same, wherein a thickness, a bumpy texture, hardness of a stitched portion of two materials with different thicknesses, such as a fastener tape and a main material, would be reduced; the stitched portion would be less noticeable and finished to be simpler; and the strength of the stitched portion may be ensured.

- the two sewing needles 1 and 2 are arranged parallel in the direction (the right and left direction in the Figure) that is perpendicular to the material feed direction (from the front side to the back side of the Figure).
- the sewing needles 1 and 2 are configured to be moved upward and downward and to be swayed in the right and left direction of the Figure by a swaying mechanism, which is not shown.
- the needle thread 16 is passed through a thread hole of the sewing needle 1, and the needle thread 18 is passed through a thread hole of the sewing needle 2.
- the vertical full rotation shuttle 4 is a shuttle which rotates counterclockwise in the Figure about a rotary shaft that is parallel to the material feed direction.
- the shuttle 4 includes a bobbin (not shown) around which the bobbin thread 20 is wound, and a sword tip (not shown) which widens loops of the needle threads 16 and 18, or the like.
- the throat plate 3 is formed with holes through which the sewing needles 1 and 2 pass.
- the sewing machine used for stitching the tape edge 12A and the material edge 14A comprises: a material presser 30 (see FIG. 7 ) for pressing the fastener tape 12 and the main material 14 that is thicker than the fastener tape 12 against the throat plate 3 at an equal pressure; and a material feeding mechanism which includes feed dogs 40a, 41a, 40b and 41b (see FIG. 8 , etc.) for feeding the fastener tape 12 and the main material 14 at different feed rates (or feed speeds).
- a material presser 30 see FIG. 7
- a material feeding mechanism which includes feed dogs 40a, 41a, 40b and 41b (see FIG. 8 , etc.) for feeding the fastener tape 12 and the main material 14 at different feed rates (or feed speeds).
- the sewing needles 1 and 2 with the needle threads 16 and 18 having passed through the thread holes thereof are caused to penetrate through the turning points 16B and 18A, respectively, and the vertical full rotation shuttle 4 is rotated while the sewing needles 1 and 2 are being pulled upward.
- the loops of the needle threads 16 and 18 are widened by the sword tip of the vertical full rotation shuttle 4, the bobbin thread 20 is caused to pass through the loops.
- the needle threads 16 and 18 are pulled upward. This causes the needle thread 16 and the bobbin thread 20 to form a knot at the turning point 16B and the needle thread 18 and the bobbin thread 20 to form a knot at the turning point 18A.
- the fastener tape 12 and the main material 14 are fed in the Y direction, and the sewing needles 1 and 2 are swayed rightward in the Figure so as to penetrate through the turning points 16A and 18B, respectively.
- the vertical full rotation shuttle 4 is rotated while the sewing needles 1 and 2 are being pulled upward. This causes the needle thread 16 and the bobbin thread 20 to form a knot at the turning point 16A and the needle thread 18 and the bobbin thread 20 to form a knot at the turning point 18B.
- the fastener tape 12 and the main material 14 are fed in the Y direction, and the sewing needles 1 and 2 are swayed leftward in the Figure so as to penetrate through the turning points 16B and 18A, respectively.
- the vertical full rotation shuttle 4 is rotated while the sewing needles 1 and 2 are being pulled upward. This causes the needle thread 16 and the bobbin thread 20 to form a knot at the turning point 16B and the needle thread 18 and the bobbin thread 20 to form a knot at the turning point 18A.
- the stitched portion of the sewn product 10 produced by sewing the tape edge 12A and the material edge 14A together via two-row zigzag stitching with two needle threads 16 and 18 and one bobbin thread 20 has a sufficient amount of tensile strength since the density of the tape edge 12A and the material edge 14A is increased by the tension of two needle threads 16 and 18 and one bobbin thread 20.
- the tape edge 12A and the material edge 14A are sewn with a small number of threads, i.e. three threads, it is possible to reduce the thickness of the stitched portion compared to that of the stitched portion with six threads using a flat seamer sewing machine. This can reduce the unevenness of the stitched portion and a bumpy texture or make the stitched portion less noticeable.
- the width of the stitched portion can be reduced compared to that of a stitched portion with six threads using a flat seamer sewing machine, the former stitched portion can be made much less noticeable.
- the sewn product 10 is a garment such as an outerwear in which the stitched seams are exposed to the outside, it is possible to improve the quality of design by making the stitched portions less noticeable.
- the tape edge 12A is overedge-stitched with the needle thread 16 and the bobbin thread 20 and the material edge 14A is overedge-stitched with the needle thread 18 and the bobbin thread 20, the tape edge 12A and the material edge 14A can be prevented from being untied.
- the fastener tape 12 and the main material 14 are pressed onto the throat plate 3 at an equal pressure by the material presser 30 (see FIG. 7 ).
- the feeding of the fastener tape 12 and the main material 14 in the Y direction is set such that the feed rate of the main material 14 which is placed in the right side will be slightly higher than the feed rate of the fastener tape 12 which is placed in the left side, by the left-hand feed dogs 40a and 41a and right-hand feed dogs 40b and 41b (see FIGs. 7 and 8 ) of the material feeding mechanism.
- the reason for such control is as follows.
- the main material 14 is thicker than the fastener tape 12, if they are sewn by using a usual sewing machine foot, the thinner fastener tape 12 could not be pressed firmly by the sewing machine foot. If they are actually sewn in such a state, since the sewing machine feeds the fastener tape 12 intermittently, the pressure to press the material and tape would be changed, resulting in uneven feeding or pitch failure. In order to prevent them, for applying an equal pressure to the fastener tape 12 and the main material 14 respectively even if they have different thicknesses, the sewing machine foot that has a seesaw function as the material presser 30 is used to press the material and tape.
- the inventors of the present invention have found that, when the fastener tape 12 and the main material 14 are sewn while they are pressed at the same pressure, there are generated in the fastener tape 12 wrinkles that wave in the longitudinal direction. Further, the inventors have found a cause that, when the fastener tape 12 and the main material 14 are withdrawn underneath the material-press parts that apply the equal pressure to them respectively, the main material 14 that is thicker than the fastener tape 12 is stitched in a state of being slightly stretched in the feed direction, and the stretched main material 14 is shrunk after being stitched, thereby causing such wrinkles. In order to prevent this, the feed rate of the thicker main material 14 under the equal press is set to be slightly higher than the feed rate of the fastener tape 12.
- FIG. 7 is a front explanatory view that illustrates a state where the fastener tape 12 and the main material 14 are pressed against the throat plate 3 at an equal pressure by the material presser 30 of the sewing machine.
- the reference numerals 40a and 41a denote left feed dogs for feeding the fastener tape 12 in the feed direction (the direction from front to rear of FIG. 7 ), and the reference numerals 40b and 41b denote right feed dogs for feeding the main material 14.
- the fastener tape 12 has elements 15 on its edge which is opposite, in the width direction, to the edge that is to be stitched with the main material 14.
- the material presser 30 comprises: a main body 31; and a pair of left and right material- press parts 32a and 32b that are extended downward and frontward (toward the front of FIG. 7 ) from the main body 31.
- the left material press part 32a presses the fastener tape 12
- the right material press part 32b presses the main material 14.
- the main body 31 incorporates an interlocking mechanism (a seesaw mechanism), which can equalize both pressures of the material-press parts 32a and 32b for pressing materials with different thicknesses, by accordingly lowering one of the material-press parts 32a and 32b when the other is raised.
- Such an interlocking mechanism is disclosed in, for example, JP S56-17112 B .
- the fastener tape 12 and the main material 14 are pressed onto the throat plate 3 at an equal pressure by the material press parts 32a and 32b, respectively.
- FIG. 8 illustrates the left feed dogs 40a and 41a and the right feed dogs 40b and 41b that are exposed upward from openings of the throat plate 3 that is incorporated in a table (not illustrated) of the sewing machine.
- These feed dogs 40a, 41a, 40b and 41b are shown also in FIG. 7 .
- the feed dogs 41a and 41b are divided into forth and back portions in the feed direction with a needle hole between the forth and back portions.
- the left feed dogs 40a and 41a are for feeding the fastener tape 12
- the right feed dogs 40b and 41b are for feeding the main material 14.
- a feed rate of the right dogs 40b and 41b is set to be slightly higher than that of the left feed dogs 40a and 41a.
- Such a technique that can set each feed rate of the left and right feed dogs separately and independently is disclosed in JP H3-191984 A , for example.
- the tape edge 12A and the material edge 14A are stitched together without overstretching or overshrinking one of the fastener tape 12 and the main material 14 compared to the other. Thereby, waving of the fastener tape 12 in the longitudinal direction can be prevented.

- the most preferable range of the length (T), in the width direction, of the left and right fastener tapes 12 in the element-closed state is 2.33 to 2.60 times (14/6 to 13/5) of the length (E) of the left and right elements 15 in the width direction.
- the preferable range is twice to three times, if considering error spans of the processing of the sewn products and their visual impressions.

- the needle thread 16 and the bobbin thread 20 which are interlocked together surround the tape edge 12A.
- the needle thread 18 and the bobbin thread 20 which are interlocked together surround the material edge 14A.
- the tension of the needle thread 22 and the bobbin thread 20 acts so as to compress the portions of the tape edge 12A and the material edge 14A that are surrounded by the needle thread 22 and the bobbin thread 20. This consequently increases the density of the surrounded portions of the tape edge 12A and the material edge 14A.
- the tension of the needle thread 16 and the bobbin thread 20 acts so as to compress the portion of the tape edge 12A that is surrounded by the needle thread 16 and the bobbin thread 20. This consequently increases the density of the surrounded portion of the tape edge 12A.
- the tension of the needle thread 18 and the bobbin thread 20 acts so as to compress the portion of the material edge 14A that is surrounded by the needle thread 18 and the bobbin thread 20. This consequently increases the density of the surrounded portion of the material edge 14A.
- the tensile strength of the stitched portion can be increased than that of the sewn product 10 according to the above-described embodiment.
- the sewn product 100 may be made using three sewing needles in the similar method as in the sewn product 10 as described above.
- the tape edge 12A of the fastener tape 12 and the material edge 14A of the main material 14 that is thicker than the fastener tape 12 are stitched together, but the main material 14 may be thinner than the fastener tape 12.
- the feed rate of the fastener tape 12 is set to be slightly higher than that of the main material 14 while they are pressed at an equal pressure.
- the turning points 16A and 18A are disposed on the boundary line L of the tape edge 12A and the material edge 14A, the turning points 16A and 18A may be disposed on the tape edge 12A or on the material edge 14A.
