The loom has five major movements, which are the opening movement, the weft insertion movement, the beating-up movement, the let-off movement and the winding movement.
The opening movement is based on the requirements of the fabric organization, and the heald frame is driven up and down by the opening mechanism, and the warp threads worn on the heald are divided into upper and lower layers to form a shed and create conditions for weft insertion.
The weft insertion movement is to introduce the weft thread on one side of the shed to the other side of the shed through the weft insertion mechanism.
The beating-up movement is that the reed in the beating-up mechanism drives the weft thread in the shed to the loom, so that the weft thread and the warp thread are interwoven into a fabric with a certain tightness.
The let-off movement is that the warp on the warp shaft is continuously sent out by the let-off mechanism to keep the tension of the warp constant, so that the weaving can be carried out continuously.
The coiling movement is that the coiling mechanism guides the fabric through the chest beam, the pressing roller and the coiling roller, and successively rolls it on the cloth coiling roller with uniform tension.
Whether it is a shuttle loom or a shuttleless loom, weaving is completed through the above five major movements, so the five major movements are the foundation of the loom and are indispensable movements.
