The whole machine is divided into three parts: spandex yarn feeding, stretching and wrapping and loose coiling. When working, the upper and lower two groups of hollow spindles are driven by the dragon belt and rotate in opposite directions, and the outer covering filament on the hollow spindle is drawn out, twisted, and wrapped on the spandex core yarn worn out of the hollow spindle. The wrapping yarn warp lead roller and reciprocating yarn guide are wound into parallel packages.
