The material sensor 91, the feed sensor 92 and the travel sensor 95 continuously detect and communicate with the controller 13, and the controller 13 drives the cutting motor 74 to drive the cutting blade 75 to rotate. The controller 13 drives the mandrel cylinder 44 to drive the mandrel main support 41 to move, so that the mandrel extends towards the wool sleeve feeding mechanism.

The sleeve feeding mechanism retreats, the controller 13 does not receive the signal sent by the stroke sensor 95, the controller 13 drives the mandrel motor 46 to drive the mandrel 45 to rotate, the mandrel 45 drives the sleeve 10 to rotate, and then the cutting cylinder 73 drives the cutting middle seat 71 to move so that the cutting knife 75 cuts the sleeve 10.
