Description

1 TARIFF A SINGLE, UNIT LUPER TECHNICAL AREA 5 The invention relates to the performance of the sewing process by the needle in industrial sewing machines. a single piece that guides the lower thread during the process, enabling the formation of a knot with the upper thread. It is related to a looper. PREVIOUS TECHNIQUE Industrial sewing machines are powerful enough for sewing thick fabrics. and must include durable materials. Products sewn from the aforementioned fabrics The strength of the stitching depends on the sewing machine used for the stitching process. The strong bonding of the threads during the sewing process ensures the durability of the sewn product. It has a direct impact. Ensuring that the stitches made on sewing machines are durable and strong. 15 In this way, the lower thread is tied to the upper thread by the looper, creating a knot. However, in thick fabrics, the looper needs to adapt to the fabric thickness and density, and It must be resistant to high tension. To improve stitch quality, the looper... Mechanical durability must be ensured. In the known state of the technique, an independent looper is used for each thread. This situation is 20 Multiple loopers on the assembly element in multi-row sewing machines This leads to space constraints in placement and therefore in multi-row machines. This increases production costs. Also, each looper has to be produced separately. This creates an economic disadvantage. Furthermore, maintenance costs are high. This is because each looper needs to be checked regularly and replaced if necessary. 25 is necessary. In the known state of the art, the assembly of each looper in multi-row sewing machines. Time and labor are wasted during the process. Improper assembly can lead to stitching problems. This negatively affects its quality. Disassembly of the system and reassembly during the process. Assembly takes a long time and causes delays in the production line. Also 30 2 The complexity of looper designs, vibrations or misalignment that may occur in the system This can cause problems. In this case, it can negatively affect the quality of the stitching. It is designed according to a fixed seam spacing in the known state of the art. This is 5 in production. applications that require variability in stitch spacing, as well as not providing flexibility. It limits the capacity to implement. In conclusion, all the problems mentioned above necessitate innovation in the relevant field. It has brought it to this state.

To ensure comprehension, it is explained with examples that do not create any limiting effects. 4 The subject of the invention is the sewing process by the needle (40) in industrial sewing machines. during the process of guiding the lower thread and forming a knot with the upper thread. It relates to a single looper (A) providing 5. The invention is presented as having the following elements:  To enable the aforementioned monolithic looper (A) to form a knot The drive shaft (10) that provides the +C and –C oscillation motion,  The movement of the mentioned monolithic looper (A) by the drive shaft (10) to ensure that it is positioned on the mentioned drive shaft (10) providing connecting piece (20),  A monolithic unit positioned on the aforementioned connecting piece (20) The connection that enables the looper (A) to be fixed to the connecting piece (20). element (30), The elements constituting the invention and their functions within the invention are given above. 15 The relationship and working principles of the elements mentioned are explained below. is given For illustrative purposes, the movement of the horizontal axis in the + and - directions along the X-axis is shown. to define the Y-axis and the C-axis to define vertical movement in the + and - directions. + and – in clockwise and counterclockwise directions (movement from the Y-axis to the X-axis) 20 It describes the movement. Figures 1 and 2 show a single looper (A) connected to a sewing machine. A one-piece looper (A) enables knot formation during the sewing process. One-piece a looper (A) guides the lower thread and upper thread during the sewing process to create a knot It consists of the upper thread (not referenced) located at the top of the sewing machine, 25 It comes from a thread feeding mechanism. The upper thread is fed into the fabric by the sewing needle (40). The needle (40) is moved from the top surface downwards, that is, from the +Y direction to the –Y direction. It pierces and forms a loop to join with the lower thread. Lower thread (not referenced) The thread comes from a spool located at the bottom of the sewing machine. A one-piece looper. (A) By taking the lower thread and moving it first in the +C direction and then in the –C direction, the lower thread reaches 30° By providing a swinging motion, the lower thread attached to it, from the +Y direction of the needle (40) to –Y by passing the upper thread through the sewing needle (40) which he carries in that direction, the knot is formed It ensures that the knot is strong, as this directly affects the quality of the stitching. The aforementioned +C and –C movement of a single looper (A) is the drive shaft (10) is provided by. The drive shaft (10) of the mentioned monolithic looper (A) 5 on the aforementioned drive shaft (10) to enable its movement. Its positioning is ensured by means of the connecting piece (20). Connecting piece (20) to the connecting piece (A) of a monolithic looper positioned on (20) The fastening is provided by the connecting element (30). The mentioned needle (40) fastens the fabric. It is the main component that pierces and carries the upper thread for connecting the lower thread. Thanks to the monolithic configuration of the aforementioned looper, its mechanical complexity is reduced to 10. By reducing the number of parts, it offers a more robust structure. Similarly, it is configured as a single, monolithic unit. Another advantage of this design is that it allows for the functionality of multiple loopers with a single piece. This provides space savings within the machine and makes multi-row machines more compact. This allows for easy design. In addition, variable stitch intervals can be easily adjusted. It enables its creation, provides flexibility in production, and meets different application needs. Same 15 It shortens maintenance times and saves labor by enabling easy assembly and disassembly in a short period of time. It saves money.
