RFRL20 Rapier Loom

The RFRL20 rapier loom is designed using proven, mature technology that has been applied in various other types of Rifa weaving machines. It is a high speed weaving machine developed for energy efficiency, low vibration, and reduced noise during operation. 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 delivers large starting torque, great braking performance, and stable functioning. It can also achieve step-less speed regulation.

• Based on computer analysis and state-of-the-art 3D modeling, we have introduced the optimized rapier loom design where the beam joint and cloth take-up roller set-up has been effectively designed. The weft beat-up device is lightweight and well balanced, and the moving parts are precision made. All of the above features result in low operating noise.
• 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, specially designed USB port allows users to conveniently set weaving parameters and procedures as well as facilitates data transmission. The control system gathers information about operating conditions, monitors the running state, and exchanges real-time data to provide for automatic adjustment, fault detection and diagnosis.
• 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 ensure the loom operates with outstanding effectiveness.
• The friendly human-machine interface delivers convenience, high efficiency, and a 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.
