The KV2019 model is an upgraded and new generation of composite twisting machine innovatively launched based on the mature technology of the KV2005 model to reduce operational labor. The upper layer of this product can be initially twisted with double twist or ring ingot. The initial twist roll is 1 kilogram, and the lower layer is double twisted with 2 kilograms. The upper layer of double twist has low noise, energy saving, multiple ingots, and high output. The large roll significantly reduces operational labor.
