Various practical shuttleless looms began to appear internationally in the 1950s. For more than half a century, the needle looms have also been widely used due to the extensive application of electronic information technology, showing the obvious advantages in quality, variety and production efficiency, and quickly replaced the shuttle looms. Mechatronics technology has enabled the production automation of weaving machines to reach a high level, which plays an important role in improving the speed and production efficiency of looms, expanding varieties and improving product quality.
The webbing loom is the development direction of the world loom, and the development of the technological revolution
The shuttleless loom can best meet the development trend of the weaving process, so the needle loom is the development direction of the world loom. From the development trend of webbing machines, breakthroughs have been made in key technologies and links, such as:
Opening: In the past, the narrow loom was equipped with a large number of cam openings, and the number of multi-arm machines was limited (except for rapier looms), and now there are few cam opening devices. Taking the jet as an example, the past type dobby machine can only operate below 500r/min of the loom, which greatly limits the high-speed performance of the air jet loom, and the cam opening can be opened to 800-1000r/min. This is the past air jet loom. One of the important reasons for the willingness to configure a cam opening rather than a mechanical dobby.
In addition to the cam opening and the multi-arm opening, the loom is also equipped with a jacquard machine. The jacquard machine used in the past shuttleless loom
It is mechanical, and today it is an electronic jacquard machine. It brings the same benefits as the electronic multi-arm, which can be used at the highest loom speed
Normal operation above 1000r/min, while mechanical jacquard machines in the past generally operate normally below 250-300r/min.
