The JWYC-608 model combines the features of the 898 and 8100 models, employing eccentric weft insertion to fully optimize the weft insertion angle and force. By shortening the warp path before the loom and tilting the warp path at the loom opening, it avoids vertical movement of the loom opening when weaving double-layer or unbalanced fabrics, enabling stable weaving of higher-density varieties.
