What is a stiff machine

Each seamstress is faced with problems of processing the edges of the fabric. Knitted fabric, split fabric, knitwear on a sewing machine is very difficult to process. This is due to the fact that the lines are inelastic, and for example, the edge of knitwear will constantly succumb to deformations. In this case, the fabrics are treated with overlock, a carpet and a high machine.

The stiff (flat -haired) machine is performed by a stiff, flat seam, which is usually used for knitted edges, and sometimes for knitted products. Such devices perform only one function - a stitching seam, but with different modifications. This type of processing provides the product with strength, accuracy and beauty.

The modification of the extinguishing line is provided by different needles. It is not difficult to distinguish it. On the front side of the product, several parallel seams are represented. Snowels can also be performed by a zigzag seam, which is impossible to replace with a conventional sewing machine. The flat spacecraft works only with textured and polyester threads. They provide the reliability of the seam.

Eaty machines are with two and three needles. A pair of needles provides a narrow stitch seam. In this case, the distance between them is 5.5 mm. Three needles make a wide seam of 6.5 mm wide. With the help of so many needles, you can create several options for a flat construction. In addition, three needles of the embroidery can be adjusted, which will create both a narrow and a wide seam.
