Interlock Sewing Machine Model
- Nov 06, 2018 -

The interlock sewing machine is also called a special sewing machine, and the stitches stitched by the stitching are chain stitching stitches. The stitches are mostly used for the rolling collar, piping, hemming, seaming, stitching and trimming of knitted garments. In recent years, the styles of ready-to-wear garments have changed a lot. Interlock sewing machines are also often used in the use of quilted decorative stitches, and there are many variations in the stitching patterns of the stitching machine, such as three-needle four-line stitching (407 The number of stitches can be changed to two stitches and three stitches (line 406), or two stitches and three stitches can be changed into two stitches and four stitches or three stitches and five stitches (602 stitches or line 605) In order to better understand the use of the interlock sewing machine, the following research will be carried out from the aspects of the conveying power of the interlock sewing machine, the design of the handpiece, and the change of the stitches, and the use of the interlock sewing machine will be fully utilized.


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. Wait. The high-type stretch sewing head can be used for sewing flat cut pieces of long seam stitches; the round-mouthed arm type is designed for sewing the edges of the cuffs or the edges of the folded cuffs; The slits for sewing the cylindrical parts, such as the slits on the side of the sleeve bottom and the seams on the side of the pants; the round-in-arm type is designed for the sewing of the undercut of the underpants; It can be equipped with a beveled design to match the different shapes of the pieces. Some are designed with a quilting attachment (sewing aid) on the right side of the machine. For example, it is applied to the operation of the piping, so that the quilting attachment can be connected to the right side of the needle plate to match the quilting.
