1, the conveying power system of the Interlock sewing machine

Because the Interlock sewing machine is mostly used to sew knitted fabrics, it is often used to convey the sewing material by using the feeding power of the two groups of feeding teeth. The conveying power is that the two feeding teeth are relatively independent. The feeding teeth of the two groups can be adjusted to synchronize the conveying action, or there are quick and slow differences. When sewing a knit fabric with strong elasticity and a two-layer light knit fabric, the feeding speed of the feeding teeth can be adjusted faster than the feeding speed of the differential teeth, or the feeding speed of the feeding teeth is slower than the feeding speed of the differential teeth, and the feeding teeth are correctly adjusted. With the differential feeding speed, the fabric after sewing can be reduced in lengthening and shrinking deformation to make it beautiful.

2, the design of the nose type

The design of the head type of the Interlock sewing machine is mostly a high-profile type device. In order to match the production of various sewing processes, the design of the head type is also a round-mouthed arm type, a round-mouthed arm type, and a round-mouthed arm type. . The contour table type sewing machine head can be applied to the plane piece for sewing long seam stitches; the round mouth arm type is designed for sewing the edge of the sewn cuff or the hem; the round mouth type is The slit for sewing the cylindrical part, such as the side seam of the sleeve bottom, and the sewing of the side seam of the pants; the round mouth type is designed for the sewing of the bottom seam of the sewing pant; The head can be provided with a beveled design to match the cut pieces of different shapes. Some are designed with a quilting attachment (sewing aid) on the right side of the machine. For example, it is applied
