The seam is the last step in the production of hosiery, and the shovel must pass through the seam before it can become a sock. This process is carried out on a seaming machine (i.e., a two-wire elastic stitch sewing machine). The quality of the stitching of the toe 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 hosiery.
The requirement for suture stitching is that it must be sufficiently flexible to avoid breakage of the suture when worn. At the same time, it must be soft so that it is comfortable to wear and does not affect the appearance. Elastic seams have these advantages. The stitches are formed by the loops formed by the upper and lower wires.
The main sewing machine parts in the sewing machine are: sewing needle (commonly known as small needle) forming machine (large needle), sewing tooth (also called angle needle), seam steel and tension compensator (by thread take-up spring) And the tension disk is composed). The tension of the upper and lower lines directly affects the appearance of the socks and the elasticity of the seams of the torsion, and the tension must be equal during the suturing process.
Starting position, when the needle has left the seam, the needle and the seamer begin to move in the direction of the arrow, the needle continues down, the needle passes through the coil formed by the seamer, and then the seam is inserted Tooth groove. While inserting the slot, it passes through the two coils on the slot in turn while the stitcher continues to move downward.
Later, the stitches are withdrawn from the teeth and the coils on the stitches and the remaining stitches are taken up by the take-up mechanism to form a stitch. Then the stitches are rotated one pitch, and the second stitch is stitched. This continuously circulates to form a continuous stitch and stitches the toe.
