Reasons for spinning long head on spinning frame

The distance between "automatic doffing" and "automatic stop" in automatic forming 3 is too large, which will cause multiple heads. The standard is that when the "automatic doffing" cam is pushed to the travel controller and the doffing distance is 2-3 minutes from the spindle foot, the "automatic stop" cam is pushed to the travel controller, and then the whole machine stops, and then the whole machine keeps 5-8 laps of tail yarn inertia! The regenerated head will not grow after doffing! By the way, do you know where the No.3 molding machine is? )
