The final beating-up cross section of the swing beating-up mode is an inclined plane, which is very inconvenient when three-dimensional multilayer fabrics are woven and has negative influence on the mechanical property of the three-dimensional multilayer fabrics. And aiming at the high-density three-dimensional fabric, the beating-up inertia of the beating-up mechanism is small, and the requirement of high density cannot be met.

Although the integral structure is ingenious, the working efficiency is high, the automation degree is high, the variable-amplitude wide beating-up cannot be realized, and the beating-up inertia is low, so that the device is not suitable for high-thickness fabrics.
Therefore, although the conventional beating-up mechanism is well-established in single-layer fabric looms, the conventional beating-up mechanism obviously cannot meet the requirement of industrial production for a novel three-dimensional multi-layer fabric loom.
