There are many spindles on the warp frame of a universal circular loom. According to the width of the woven fabric and the width of the flat yarn, a specified range of warp yarns are used. Before entering the circular loom, the warp yarns are crossed and opened by the brown frame of the warp yarns. The weft shuttle moves in a circular motion through the warp yarns in the cross opening and weaves them into a tube fabric A circular loom has several shuttles, so several weft yarns are woven at the same time. For flat weaving, flat weaving machines, shuttle weaving machines, and water jet weaving machines can be used

Earlier, domestic circular looms were all imitations of imported circular looms from abroad. However, in the 1990s, this situation gradually changed. China first produced circular looms with independent intellectual property rights, and successively launched the second, third, and fourth generations of circular looms in 1991, 1993, and 1997. In August 2000, the world's first ten shuttle super circular loom SPCL-10/6000, which integrated multiple advanced technologies, was successfully developed. Subsequently, in January 2005, the world's first twelve shuttle super plastic circular loom was born and delivered to users. In November 2009, four years later, the world's first giant sixteen shuttle plastic circular weaving machine SPCL-16/10000 was ordered, and China's circular weaving machine level has now stabilized at the world's leading level
