What presser foot is used for the front bag of synchronous car stickers?

The front pocket of synchronous sewing machine is made of industrial clothes. When the existing sewing machine sews clothes, it feeds the cloth through the cloth feeding teeth on the lower cloth under the presser foot, while the upper cloth walks through the friction with the presser foot, which is easy to cause the problem that the walking speed of the upper and lower cloth is inconsistent and wrinkles. Usually, in order to sew the cloth smoothly, it is necessary to pull the lower cloth by hand or pull the cloth from the back of the presser foot, so there are often uneven stitches, jumpers or broken needles, which affect the quality of the whole garment. The content of the utility model is to overcome the shortcomings of the existing sewing machine presser foot feeding technology, and the purpose is to provide a synchronous sewing machine presser foot which can make the upper and lower layers of cloth walk consistently. In order to realize the purpose of the utility model, a cloth feeding gear is assembled in the presser foot groove at the bottom of the back side of the presser foot in the presser foot of a clothing machine consisting of a pair of left and right presser feet and a presser foot head with an inverted concave groove, and the pitch and depth of the cloth feeding gear are consistent with the cloth feeding teeth of the presser foot. The top of the left presser foot and the right presser foot are respectively provided with a concave hole, and a spring is arranged in the hole; then, the two presser feet are assembled in the inverted concave groove of the presser foot head at the same time, and the spring at the top of the presser foot abuts against the top of the groove. After adopting the above measures, the utility model has the advantages that when the clothes hanger runs, the cloth feeding teeth automatically cooperate with the cloth feeding gear to pull the cloth away, which ensures the synchronization of the upper and lower layers of the cloth and makes the lines straight. The left and right presser foot can be automatically adjusted up and down.
