RFRL20 Rapier Loom

The RFRL20 rapier loom represents the mature technology that has been applied in various other types of Rifa weaving machines. It is a high speed weaving machine designed for energy efficiency, low vibration, and reduced noise. Directly driven by a patented switched reluctance motor, the loom can freely change its weaving speed to accommodate different yarn and fabric types, whereby saving fuels by 15% than a conventional loom under the same weaving conditions. Additionally, the motor gives large starting torque, great braking performance, and stable functioning. It can achieve step-less speed regulation.

Design and Application
The shedding, weft insertion, warp let-off, and cloth take-up mechanisms have been specially designed to make various fabrics and cloth, such as denim fabric, grey cloth, wool fabric, corduroy, cotton fabric and blended fabric(for upholstery use), lightweight and medium-thick industrial fabric, flax, and fiberglass.

Features
1. Based on computer analysis and state-of-the-art 3D modeling, we have brought out the optimized rapier loom design where the beam joint and cloth take-up roller set-up have been effectively designed, the weft beat-up device is lightweight and well balanced, and the moving parts are precision made. All those said features make low operating noise a possibility.
2. To achieve digital control, the loom adopts multi-core, multibus computer control technology. Its high-performance CPU not only manages and monitors all the electronic control units within the computer, but also controls external devices such as the dobby and jacquard via the input port and output port. The unique designed USB port allows users to conveniently set weaving parameters and procedures as well as facilitates data transmission. The control system is able to gather information about operating conditions, monitor the running state, and exchange real-time data to provide for automatic adjustment, fault detection and diagnosis.
3. A super motor delivers the power necessary for the rapier loom to complete such motions as weft finding and slow weaving. It incorporates highly automatic numeric control technology which enables various automatic functions, including automatic cloth-fell compensation, cloth-fell finding, warp tension adjustment, network monitoring, and fault diagnosis. Those powerful functions insure the loom good quality.
4. The friendly human-machine interface makes for convenience, high efficiency, and large amount of data input and output. Its large display screen facilitates two-way communication so that users can set as well as adjust processing parameters and manufacturing procedures. The unique parameter adjustment device makes machine operation and re-setting easier than before. It also greatly reduces changeover time.
