The seam head is the last process in the production of knitted socks. The socks must pass through the seam head to become socks. This process is performed on a sewing machine (ie, a double-thread elastic sewing machine). The quality of the sock head stitching and the tension of the two stitches directly affect the appearance and quality of the socks *, so this process is also an important process in the production of knitted socks *.

The requirement for hosiery head stitching is that it must have sufficient elasticity to prevent the suture from breaking when worn. At the same time, it should be soft to make it comfortable to wear without affecting the appearance. Elastic seams have these advantages. The stitch is formed by loops formed by the upper and lower threads.

The main sewing machine parts in the sewing machine are: sewing needle (commonly known as small needle), sewing device (large needle), sewing tooth (also known as angle needle), sewing head steel and tension compensator (by thread take-up spring And tension disc). The tension of the upper and lower threads directly affects the appearance of the socks and the elasticity of the sock head stitching. The tension must be equalized during the stitching process.

In the starting position, the sewing needle has left the teeth, and the sewing needle and the sewing device start to move in the direction of the arrow. The sewing needle continues to move downward. Tooth slot. While inserting the tooth slot, it passes through the two coils on the teeth in sequence, and the slitter continues to move downward.

After the stitches are withdrawn from the teeth and the stitches and stitches remaining on the teeth are taken up by the thread take-up mechanism, a stitch is formed. Then the teeth are rotated through a tooth pitch, and the second stitch is stitched. This continuously loops to form a continuous seam to sock the toe.
