Advantages of the warping machine

The sectional warping machine is a weaving preparation machine, driven by a motor and controlled by a PLC. It winds the yarns of different specifications on the pan head according to the needs. In warping, according to the number and length of warp yarns required by the process, under the same tension, the package yarn is wound into a warp beam in parallel, at a constant speed, and neatly for use by the warp knitting machine. In the warping process, not only the warp beam is required to be well formed, but also the weaving performance of the warp yarn should be improved, the warp yarn defect should be eliminated, and a good foundation for weaving should be provided. Frequency conversion speed regulation, electronic length meter, stable and frequent reversing movement. There is no need to separate the yarn and then draw the yarn, saving labor and improving the production efficiency of the order. The yarn comes out smoothly, without pressing the yarn and without lint. Even tension. Warp yarns must have proper tension while warping while maintaining warp elasticity and tension as much as possible. During the warping process, the tension of the full width of the warp is as uniform as possible. The yarns are arranged evenly. The warp yarn arrangement and winding density on the warp shaft should be uniform (referring to the transverse direction of the warp beam and the inner and outer layers of yarns), and the surface of the warp beam should be straight, and there should be no unevenness. The winding density is uniform. Warp number, length or color warp arrangement cycle conform to the requirements of weaving process design. The warping machine has high production efficiency and less thread return.

Ribbon items are widely used in clothing, industry, military supplies, transportation and other industries. Webbing also plays an indispensable role in our lives. For example, the seat belt in our car, the shoulder strap of the school bag, the ribbon of the badge, the elastic belt and so on. In the beginning, the ribbons were all produced by hand, and the raw materials were cotton thread and hemp thread. With the progress of science and technology and social development, the ribbon loom began to come out, which greatly promoted the productivity of the ribbon. At the same time, the raw materials of webbing have also begun to diversify, from cotton thread and hemp thread to nylon, vellum, polyester, polypropylene, spandex, viscose, etc., and gradually formed three types of technology, namely knitting, weaving and knitting.

The earliest webbing is based on the weaving (woven) process and the yarn warp and weft interweaving. After twisting, the yarn is warped into a bobbin (pan head), the weft yarn is shaken into a bun, and the ribbon is woven on the loom. In the past, this weaving method also used hand-pulled wooden looms and iron-wood looms. With the progress of society, the professional technicians at that time converted the 1511 loom into a ribbon loom, and this ribbon loom is still widely used until now.

At the beginning, the shuttleless webbing research group with workers as the main body in the webbing industry successfully designed and manufactured a high-speed single shuttleless webbing machine by itself, is a pioneering work in the history of Chinese ribbon technology.

Subsequently, due to the popularization of continuous dyeing and ironing machines for tapes, the processing of colored tapes developed from the traditional process of dyeing and weaving to weaving and dyeing, weaving and bleaching, and ironing and processing. production ranks. Slowly, the industry introduced high-speed shuttleless ribbon looms, ironing machines, wrapping machines, warping machines, etc. from Switzerland, Italy, and the Federal Republic of Germany, and ribbon technology entered a new stage of development.

The progress of webbing technology has brought about the upgrading of products. The first-generation rubber ingot belt was successfully trial-produced. Immediately afterward, an upgraded rubber ingot belt was developed, which has the characteristics of soft, light, thin, firm, small elongation, low impact force, and short and flat joints. Later, the car seat belt for the Santana car was successfully trial-produced. After more than two years of research and trial production, the product quality has reached QC49-92 and TL-VW470 standards.

Nowadays, although the machine and equipment of the webbing are very sophisticated, and the webbing technology is already proficient, the development and innovation of the webbing machine must continue.

The ribbon looms slowly replaced manual work, and the thread used on the ribbon loom was also labored by the warping machine. The warping machine can improve production efficiency and can be set according to the number of segments of the line you need. In addition, people sometimes need to produce some orders and samples. At this time, it is obviously very wasteful to continue to use large warping machines. Therefore, the sample warping machine also appeared, one or two can be quickly put on the pan head, and adjusted according to the thickness of the line and the number of segments. Fully intelligently controlled stretch yarn output, close to the beam without pressing the yarn, it can protect the yarn from hurting.
