Features

Features of RFRL50 High Speed Rapier Loom

1
1

The rapier loom is highly networked and intelligent, enabling centralized management and control of the machine group in the workshop.


2
2

The weft-beating mechanism is located in the middle of the weaving machine under the fabric, which is conducive to strong weft-beating and high-speed operation.


3
3

Optimized four-axis space linkage sword transmission mechanism can realize stable and precise high-speed weft drawing-in.


4
4

The control system of the loom adopts fiber optic communication technology, with fast response of the motor and quick start and stop, which is conducive to improving the quality of the fabric.


5
5

The design of heavy conjugate cam contour curve and other structures to adapt to the weft beating force of heavy fabrics improves the stability of the high-speed weft beating structure.
