Description

Technical Field

[0001] The utility model relates to the technical field of sewing machines, in particular to a presser foot for sewing machines. Background Art

[0002] The sewing machine presser foot is an indispensable component in the feeding mechanism of the sewing machine. Various forms of sewing machine presser feet play a very important role in the production process, such as the sewing machine presser foot for sewing visible stitches, hidden zippers, pleating sewing machine presser feet, etc. It is very important to choose different sewing machine presser feet in different sewing operations.

[0003] After searching, it was found that the Chinese patent with announcement number CN220012991U discloses a double-blind-thread sewing machine presser foot, including a presser foot handle and a presser foot plate, the presser foot plate is provided with a sewing hole for a core rope, a bag material and two sewing needles to pass through, one side wall of the sewing hole is provided with a core rope feeding hole connected to the sewing hole, and the other opposite side wall is provided with a discharge port connected to the sewing hole, and a bag material forming part is provided in the sewing hole, and the bag material forming part is used to form the bag material into a wrapped state after the bag material passes through. Among them, paragraph

[0029] of the specification, a double concealed thread sewing machine presser foot, includes a presser foot handle 1 and a presser foot plate 2, the presser foot plate 2 is provided with a sewing hole 3 for a core rope, a bag material and two sewing needles to pass through, a side wall of the sewing hole 3 is provided with a core rope feeding hole 4 connected to the sewing hole 3, and the other opposite side wall is provided with a discharge port 5 connected to the sewing hole 3, and a bag material forming part 6 is provided in the sewing hole 3, the bag material forming part 6 is used to shape the bag material into a wrapped state after the bag material passes through, the wrapped state is a state in which both sides of the bag material a are bent toward the center, and this state is formed when the bag material a passes through the bag material forming part 6, the wrapped bag material and the core rope are pulled out from between the discharge port 5 and the product to be sewn to form a decorative strip state, and while the decorative strip is pulled out, two sewing needles are respectively inserted into the inner side of the bend for sewing, d is the stitching position, so there is no visible thread after sewing the decorative strip. Specifically, when using the presser foot, there is no need to wrap the core rope b with the wrapping material a and put them into the sewing hole 3. It is only necessary to pass the core rope b and the wrapping material a through the core rope feeding hole 4 and the wrapping material forming part 6 respectively, and then pull them out from the discharge hole 5 together, so that a decorative strip can be naturally formed. When the decorative strip is pulled out, two sewing needles pass through the sewing holes to sew the decorative strip onto the product c to be sewn. At the same time, the wrapping material a is in a wrapped state to press the core rope b onto the product c to be sewn, and the core rope b will not slide at will, making the decorative strip structure compact and more beautiful as a whole.

[0004] At the same time, a Chinese patent with announcement number CN219653261U discloses a double-blind-line decorative strip sewing pull-tube presser foot, which is used in sewing machines and includes a presser foot body; wherein, one end of the presser foot body is provided with a feed port and a cotton core feed port arranged on one side of the feed port, and one side of the presser foot body is provided with a feed hole.
