Description

Technical Field

[0001] The utility model relates to the field of clothing production and processing, in particular to a tool for assisting in sewing pleated elastic bands. Background Art

[0002] Pleated elastic bands add a rich and varied look to clothing and are widely used in the design of tops, skirts, sleeves, and other garment components. This is particularly true on the back of dresses, where elastic bands are often sewn to create a pleated effect, adding a sense of tightness and airiness. Currently, hand-sewing back pleated elastic bands typically involves a three-in-one flat-bed sewing process, including waist taping and concealed threading; hand-stitching the waist taping elastic band; applying the waist taping on one side of the concealed elastic line; flat-bed sewing the waist taping with a 0.1-thread upper thread; and finally, folding the waist taping with a 0.1-thread lower thread. This sewing process results in a loose elastic band and uneven stitching, which can easily lead to defects in the finished product.

[0003] In view of this, the utility model proposes a tool for assisting in sewing pleated elastic bands, which can realize semi-automatic sewing of pleated elastic bands, saving a lot of sewing time, and the sewn finished products have uniform stitching and high yield. Summary of the Invention

[0004] To achieve the above objectives, the present invention employs a technical solution: a tool for assisting in sewing pleated elastic bands, comprising a machine mounting frame, a first fabric channel, and a second fabric channel. During sewing, the elastic band wrapper enters the first fabric channel, and the elastic band enters the first fabric channel through the second fabric channel, with the elastic band wrapper at the bottom and the elastic band at the top.

[0005] Furthermore, the first fabric channel is a closed channel provided with an upper plate and a lower plate.

[0006] Furthermore, the width of the first fabric channel gradually decreases from the feed port to the discharge port.

[0007] Furthermore, the width of the outlet of the first fabric channel is consistent with the width of the elastic band.

[0008] Furthermore, the lower plate is gradually rolled inwardly toward the upper plate from the feed port to the discharge port, forming a space within the rolled edge.

[0009] Furthermore, the upper plate is welded to the feed port curling of the lower plate, and the discharge port curling of the lower plate is not welded to the upper plate.

[0010] Furthermore, a top plate is welded to the discharge port curl of the lower plate.

[0011] Furthermore, the upper plate is folded at the feed port to form a second fabric channel, and the second fabric channel is an open channel.

[0012] Furthermore, the second fabric channel is provided with an elastic band adjustment device.

[0013] Furthermore, the elastic band adjusting device is welded on the second fabric channel, and the elastic band adjusting device includes a frame, a knob, and a spring.

[0014] Furthermore, a small hole is provided on the frame, and the knob acts on the spring piece through the small hole, so that the spring piece compresses or loosens the elastic band.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects: because the width of the elastic band to be sewn is always greater than the elastic band, when the elastic band enters the first fabric channel, the portion of the elastic band that is wider than the elastic band enters the space within the hem and wraps around the elastic band at the first fabric channel outlet. The top plate of the outlet hem restrains the wrapped portion to prevent displacement. During sewing, the main garment piece is then covered, and double-needle sewing is performed at the first fabric channel outlet. The stitching is performed while the sewn area is pulled at the outlet, achieving the desired pleated elastic band. Furthermore, the elastic band adjustment device can adjust the desired tension.

DETAILED DESCRIPTION

[0021] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0022] like Figure 1 、 2As shown, a tool for assisting in sewing wrinkled elastic bands comprises a machine frame 1, a first fabric channel 2, and a second fabric channel 3. During sewing, the elastic band wrapper 4 enters the first fabric channel, and the elastic band 5 enters the first fabric channel through the second fabric channel, with the elastic band wrapper at the bottom and the elastic band at the top.

[0023] like Figure 3 As shown, the first fabric channel comprises an upper plate 21 and a lower plate 22, forming a closed channel. The width of the first fabric channel gradually decreases from the feed inlet 23 to the discharge outlet 24, with the width of the discharge outlet 24 being consistent with the width of the elastic band to be sewn. The lower plate 21 gradually rolls inward toward the upper plate 22 from the feed inlet to the discharge outlet, creating a space within the rolled edge. The weld 25 between the upper and lower plates is rolled at the feed inlet of the lower plate, forming a closed channel. Meanwhile, the rolled edge of the discharge outlet of the lower plate is not welded to the upper plate, leaving a space. Finally, a top plate 26 is welded to the rolled edge of the discharge outlet of the lower plate.

[0024] like Figure 4 As shown, the upper plate folds over at the feed port to form a second fabric channel 3, which is open. An elastic band adjustment device 31 is installed on the second fabric channel. The elastic band adjustment device 31 comprises a frame 311, a knob 312, and a spring 313. The frame 311 is welded to the second fabric channel. The spring 313 is a folded extension of one side of the frame. The frame has a small hole through which the knob 312 acts on the spring 313, causing it to tighten or loosen the elastic band.

[0025] When sewing, first pass the elastic band through the second fabric channel into the first fabric channel, and then adjust the elastic band adjustment device on the second fabric channel to the desired tightness. Then, place the elastic band wrapper under the elastic band and enter it through the first fabric channel. Because the width of the elastic band wrapper to be sewn is always wider than the elastic band, when the elastic band wrapper enters the first fabric channel, the part of the elastic band wrapper that is wider than the elastic band will enter the space inside the hem and wrap the elastic band at the outlet of the first fabric channel. The top plate on the hem of the outlet restricts the wrapped part to prevent displacement. Finally, cover the main body of the garment to be sewn, and perform double-needle sewing at the sewing position 6 of the outlet of the first fabric channel. While the needle is moving, the sewn part is pulled at the outlet to achieve the sewing of the pleated elastic band.

[0026] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the description and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
