Description

Technical Field

[0001] The present invention relates to blades, and particularly to seamless blades, headbands, clothing bands, and product fixing bands.

Background Art

[0002] When one end of an existing connecting belt is fixed to a closed ring, generally, after passing the connecting belt through the closed ring, it is bent 180° and sewn to fix the connecting belt and the closed ring. Such a fixing method forms a two-layer stepped structure at the position of the seam. While the outer shape is relatively abrupt and not beautiful, when the stepped structure contacts the body, the foreign body sensation becomes prominent. When contacting and rubbing for a long time, the user feels a tingling sensation, and in some cases, the skin may be scratched.

Summary of the Invention

Problems to be Solved by the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a seamless blade, a headband, a clothing band, and a product fixing band.

Means for Solving the Problems

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows: A seamless blade including a base segment, wherein the base segment is composed of an overall segment and a branch segment located at the end of the overall segment. The overall segment and the branch segment are integrally knitted and formed. The branch segment includes an upper branch portion and a lower branch portion. The length of the lower branch portion is greater than the length of the upper branch portion. The end of the lower branch portion is folded back to align with the end of the upper branch portion to form a joint portion. The parts on both sides of the joint portion are integrally connected by ultrasonic welding or adhesion. The folded-back part of the lower branch portion forms a closed connection ring.

[0005] The base segment is cut from a single long belt, which is composed of single-layer segments and two-layer segments installed at intervals. The entire segment is the single-layer segment, and the branch segment is formed by shearing while shifting the two-layer segment.

[0006] The long belt is woven by upper warp threads, upper coated warp threads, upper weft threads, lower warp threads, lower coated warp threads, and lower weft threads. When weaving the two-layer segment, the upper warp threads and upper coated warp threads are woven by intersecting only with the upper weft threads, and the lower warp threads and lower coated warp threads are woven by intersecting only with the lower weft threads. When weaving the single-layer segment, the entanglement operation between the upper warp threads and upper weft threads remains unchanged, and the entanglement operation between the lower warp threads and lower weft threads remains unchanged. The upper coated warp threads are woven by intersecting with the upper weft threads and lower weft threads, and the lower coated warp threads are also woven by intersecting with the upper weft threads and lower weft threads.

[0007] A buckle having a closed connection ring is connected to the connection ring, and the lower branch portion is ultrasonically welded or adhered after passing through the connection ring.

[0008] A clothing band including the seamless blade as described above, wherein connection rings are installed at one end or both ends of the seamless blade.

[0009] A clothing band including the seamless blade as described above, wherein connection rings are installed at one end or both ends of the seamless blade.

[0010] A product fixing band including the seamless blade as described above, wherein connection rings are installed at one end or both ends of the seamless blade.

Advantages of the Invention

[0011] The beneficial effects of the present invention are as follows: The base segment of the present invention is composed of an overall segment and a branch segment located at the end of the overall segment. The overall segment and the branch segment are integrally knitted and formed. The branch segment includes an upper branch portion and a lower branch portion. The length of the lower branch portion is greater than the length of the upper branch portion. The end of the lower branch portion is folded back to align with the end of the upper branch portion to form a joint. The parts on both sides of the joint are integrally connected by ultrasonic welding or adhesion. The folded part of the lower branch portion forms a closed connection ring, which has relatively good connection strength, can withstand relatively large tensile force and external force, and is less likely to show detachment or breakage. Moreover, the connection at the joint is flat, making the overall thickness of the overall segment and the branch segment consistent, preventing the appearance of a stepped structure, which may cause a foreign body sensation when the user uses it. Moreover, the surface is smooth and flat, and the appearance is more beautiful, and it can be applied to headbands, clothing belts, product fixing belts, etc.

Modes for Carrying Out the Invention

[0013] To make the purpose, technical solution and advantages of the present invention more clear, hereinafter, with reference to the accompanying drawings related to specific embodiments, the present invention will be described in more detail. In addition, when there is no conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0014] It is understood that these descriptions are illustrative and not intended to limit the scope of the present invention.

[0015] Hereinafter, one of several embodiments of the present invention will be described in relation to the accompanying drawings.

[0016] Referring to FIGS. 1 to 8, it is a seamless blade including a base segment 1, wherein the base segment 1 is composed of an overall segment 2 and a branch segment 3 located at the end of the overall segment 2. The overall segment 2 and the branch segment 3 are integrally braided and formed. The branch segment 3 includes an upper branch portion 4 and a lower branch portion 5. The length of the lower branch portion 5 is greater than the length of the upper branch portion 4. The end of the lower branch portion 5 is folded back to align with the end of the upper branch portion 4 to form a joint portion 6. The parts on both sides of the joint portion 6 are integrally connected by ultrasonic welding or adhesion. The folded-back part of the lower branch portion 5 forms a closed connection ring 7, which has relatively good connection strength, can withstand relatively large tensile force and external force, and is less likely to show situations of detachment or breakage. Moreover, the connection at the joint portion 6 is flat, making the overall thickness of the overall segment 2 and the branch segment 3 consistent, so that no stepped structure appears, which may cause a foreign body sensation when the user uses it. Moreover, the surface is smooth and flat, and the appearance is more beautiful.

[0017] The parts on both sides of the joint 6 are generally bonded to the tip of the lower branch part 5. The connection ring 7 is completely formed by the lower branch part 5. Between the parts on both sides of the joint 6 and the lower branch part 5, a reinforcing sheet 11 (the reinforcing sheet may be made of PA, TPU, PUR, etc., or a mixed hot melt paste of these, and the reinforcing sheet may be a non-elastic or slightly elastic material) with hot melt paste applied on both sides is inserted and thermocompression bonded (the thermocompression bonding is the same as the prior art and there is no particular requirement. The applied rubber may be locally dot-applied or fully applied). The entire parts on both sides of the joint 6 are connected to the tip of the lower branch part 5 in one layer, and are non-elastic or slightly elastic at the welded and pressure-bonded part and do not break at the welded and pressure-bonded part.

[0018] In addition, the parts on both sides of the joint 6 may be directly connected (in order to ensure the connection strength, a sewing method may be adopted for fixing). In this case, the connection ring 7 is formed by surrounding the upper branch part 4 and the lower branch part 5.

[0019] The base segment 1 is cut from a single long belt. The long belt is composed of single-layer segments 8 and two-layer segments 9 installed at intervals. The whole segment 2 is the single-layer segment 8. The branch segment 3 is formed by shifting and shearing the two-layer segment 9. The product produced by the braiding machine is the long belt, and then it is shifted and sheared to form several of the base bands 1.

[0020] When the long belt is woven, it is necessary to use the upper warp 12, the upper covering warp 13, the upper weft 14, the lower warp 15, the lower covering warp 16, and the lower weft 17. When the two-layer segment 9 is woven, the upper warp 12 and the upper covering warp 13 are woven by intersecting only with the upper weft 14, and the lower warp 15 and the lower covering warp 16 are woven by intersecting only with the lower weft 17. The three types of yarns of the upper warp 12, the upper covering warp 13, and the upper weft 14 and the three types of yarns of the lower warp 15, the lower covering warp 16, and the lower weft 17 are made independent of each other (as shown in FIG. 7). When the single-layer segment 8 is woven, the entanglement operation between the upper warp 12 and the upper weft 14 remains unchanged, and the entanglement operation between the lower warp 15 and the lower weft 17 remains unchanged. The upper covering warp 13 is woven by intersecting with the upper weft 14 and the lower weft 17, and the lower covering warp 16 is also woven by intersecting with the upper weft 14 and the lower weft 17 (as shown in FIG. 6), thereby forming the single-layer segment 8.

[0021] The upper weft 14 and the lower weft 17 are composite wefts composed of nylon yarn and heat fuse. During cutting, the heat fuse in the composite weft is melted and sealed using a thermal cutting process to avoid the notches from becoming scattered.

[0022] The heat fuse is one of a high-temperature polyester material or a nylon low-temperature material. The present invention adopts a nylon low-temperature material, and the proportion content of the heat fuse is selected according to different production requirements.

[0023] A buckle 10 having a closed connection ring is connected to the connection ring 7, and the lower branch portion 5 is ultrasonically welded or adhered after passing through the connection ring.

Embodiment

[0024] Example 1: Only one end of the entire segment 2 is the branch segment 3, and the other end may be the entire segment 2 itself. In such a structure, one end of the entire segment 2 is the branch segment 3, which forms the connection ring 7 and is used to connect to the buckle 10, and the other end is fixed to a product such as a shoulder strap of a backpack.

Example

[0025] Example 2: Both ends of the entire segment 2 are the branch segment 3. In such a structure, the connection rings 7 for connecting to the buckle 10 are formed at both ends. The two buckles are a child buckle and a parent buckle respectively, and can engage with each other and be applied to a binding band. For example, after folding a folding tent, the binding band is used for binding and fixing to prevent loosening.

[0026] A headband including the seamless blade as described above, wherein the connection ring 7 is installed at one end or both ends of the seamless blade.

[0027] A clothing band including the seamless blade as described above, wherein the connection ring 7 is installed at one end or both ends of the seamless blade.

[0028] A product fixing band including the seamless blade as described above, wherein the connection ring 7 is installed at one end or both ends of the seamless blade.
