Conveying power system of sewing machine

Because the sewing machine is mostly used for sewing knitted fabrics, the two groups of feeding teeth are used before and after.

The conveying power is that the two groups of feeding teeth are relatively independent.

The two groups of feeding teeth can be adjusted synchronously and conveyed, either fast or slow.

When sewing a strong knitted fabric and two layers of light knitted fabric, the feeding speed of the feeding tooth can be adjusted faster than that of the differential tooth feeding, or the feeding speed of the feeding tooth is slower than that of the differential tooth feeding, and the speed of the feeding tooth and the differential feeding can be adjusted properly, so that the fabric after sewing can be reduced and elongated and wrinkled, and the appearance will be beautiful.

The high profile type sewing head can be used for sewing long stitched stitches on the surface of the stitches. The round mouth type arms are designed for sewing the edges of the cuffs or the edges of the folded edges. The round mouth outlet arm type is used for sewing the seams of the cylindrical parts, such as the side seam of the sleeve bottom and the side seam of the trousers; the round mouth type is designed for sewing the bottom seam of the underpants, and the high-profile head can be designed with a bevel angle for sewing different types of cutting pieces.
