[0002] Air-jet looms are shuttleless looms that use jet airflow to pull the weft yarn through the shed. The working principle is to use air as the weft-introducing medium. The compressed air at the jet point generates frictional traction force on the weft yarn to pull it through the shed. This weft-introducing method enables the loom to achieve high speed and high output. Among several shuttleless looms, air-jet looms have the highest production efficiency.

[0003] The beat-up device is an important component of an air-jet loom. The beat-up device is usually connected to the beat-up beam, which drives the beat-up device to perform the beat-up operation.
