Product Features
An economical machine specially developed for sewing large bags. After professional adjustment, this machine is suitable for sewing super heavy, medium heavy and thin extra large bags. No skipping stitches when sewing heavy materials, and no wrinkles when sewing light materials. The manual presser foot can pull the four sides of the sewing machine for local reinforcement. For the sewing of packaged products with dust-proof devices, three parts need to be replaced at the needle position.
The connecting rod thread take-up and horizontal three times rotating hook are used to form a single needle double line chain stitch. By using the three times rotary hook, the bobbin thread capacity is raised to the level of gb4-1, which greatly reduces the noise, improves the work efficiency, reduces the use of spare parts and reduces the production cost. The upper and lower feeding system makes it easier to climb the slope. It is equipped with a reverse sewing device, which is more convenient to operate.
Automatic presser foot lifting and automatic reverse sewing can be realized, which greatly reduces the labor intensity of workers. During the sewing process of the lifting belt, the front and rear stitches are the same, which greatly improves the quality of the extra large bag. This machine is an ideal choice to realize high-speed and high-quality sewing of giant machines.
