The Azuma knitting machine is one of the early knitting machines created in the 1970s, when it transformed from a loop knitting machine to a high-speed knitting machine, and is a rare and valuable knitting machine with only a few in existence. The knitting speed is extremely slow, making it a low-productivity knitting machine that can only knit 1 to 2 turns per day. Because the speed is gentle, it creates a soft, puffy texture.
