1 TARIFF THERMAL THREAD CUTTING ON CHAIN ​​STITCH MACHINES 5 TECHNICAL FIELD The invention allows the chain to move across the fabric after the sewing process is completed in chain stitch machines. the stitching to start again in a different location without continuing on the outside with automatic rope cutting that enables thermal cutting of the upper and lower ropes that make up the system It is related. 10 In this method, the elements that constitute thermal shearing are also mechanical shearing. This results in a mechanical and thermal interconnected system structure. It is emerging. PREVIOUS TECHNIQUE Chain stitch machines are widely used in the textile and garment industry. 15 It is used especially in sportswear and underwear where flexible and durable seams are required. Commonly used in underwear, knitwear and crochet fabrics, and in the inseams of jeans. It is used. In the current system, the stitching must continue outside the fabric in order to cut the sewing threads. The threads used in sewing continue to form a chain, and cutting the thread also completes this chain. 20 It is a necessity to do this. In the current system, the lower seam thread is done manually. There is no area that can be cut. Therefore, the stitching is not possible on the fabric. It is not possible to complete it. In the known state of the technology, the stitching would come out of the fabric when the stitching was finished in the system. And for a while longer, chain formation is a necessity. This also means that the fringes on the fabric are 25. This causes the formation of a defect in the fabric after sewing, as per the current system. The resulting chain fringe causes visual pollution. In undesirable situations, this... Trimming the fringe also requires additional work. In multi-needle chain stitch machines, however, the mechanical shearing method cannot cut the material. Threads can form, making sewing difficult on automated sewing lines. 30 2 After the stitching process is completed on chain stitch machines, the stitching process continues. The resulting threads are then manually cut by the operators after each stitch. This causes extra time to be spent. This slows down the production speed, resulting in 5 This leads to a decrease in overall productivity. Another disadvantage of manually cutting the rope is that each cut is not the same. This makes it difficult to achieve the desired quality and length. This situation results in irregular stitches. This can lead to uneven stitching. The stitching may appear irregular, affecting the product's aesthetics and appearance. It negatively affects its quality. 10 Manual rope cutting requires the use of cutting tools. The use of cutting tools... This increases the likelihood of workplace accidents and does not ensure continuity in production. In conclusion, all the problems mentioned above necessitate innovation in the relevant field. It has brought it to this state.
