In the traditional installation method, the installation of the heald frame of the air-jet loom requires four people to cooperate to complete the operation, which is divided into two groups and located at the upper and lower positions of the loom respectively. Due to the large number of heald frames, the staff needs to work at the bottom of the machine for a long time, which not only consumes physical strength, but also has certain safety risks.
