The RFJA12 air jet loom is designed to maximize production for glass fibers. All its systems and mechanisms have been specifically constructed to facilitate the weaving of glass fibers. Those include the novel electrical control system, powerful weft beating mechanism with four connection rods, cloth take-up roller that eliminates bias filling, highly effective weft insertion assembly, negative warp let-off mechanism, suction unit, advanced cloth take-up mechanism, temple(stretcher), and selvedge shear.
Features
1. To construct an automatic control system, we use the computer which runs 32-bit version of Windows operating system to send, gather, and correct the process parameters. This control manner does not require human operation while allowing for digital management and monitoring network. Not only does this control system provide abundant information, but it also has twice the use life of the traditional intelligent keyboard.
2. Based on the characteristics of glass fiber, the computer optimized design of weft battening mechanism with four connection rods is introduced into the loom. With each beating up operation, the short-stroke reed reduces the distance that it has to travel to press the weft yarn against the cloth fell while generating little vibration and permitting longer time spent on weft insertion. Short stroke also allows the reed to give strong beating force during high speed operation of the loom, with more assurance to yield quality fabrics.
3. The rolling type cloth fell temple (stretcher) and cloth press roller eliminate the bias filling and ensure the fabric keep its tension and width while being transferred from the temple to the cloth transfer roller. There are friction materials wrapped around the surface of the cloth transfer roller and cloth take-up roller to avoid any press mark incurred by the cloth.
4. The specifically designed weft accumulator, main nozzle, aide nozzle, and relay nozzle can protect the glass fiber weft yarn from damage as well as decrease the wear of weft insertion components caused by the yarn.
5. The electronically controlled double back beam for warp let-off motion can measure out the exact warp tension and keep it at a proper level. The highly responsive AC servo motor precisely controls the let-off speed, thus ensuring the warp yarn quality.
6. The highly effective suction device sucks away the fiber fines in the air produced during weaving, thereby creating a fiber-free working environment.
7. The combined control technology of AC servo motor and angular displacement sensor assures the cloth to be tightly tensioned. The big cloth take-up roller requires little standing room, and allows a maximum 800mm-diameter cloth roll to be wound on it
8. Given the high hardness of the glass fiber, we have designed this chopping shear to remove the redundant warp ends. Such a shear requires little production cost as it gives good cutting performance and long use life.
