Vacuum assisted pull down foils
For good tailthreading it is essential that tail is positioned correctly vs. tail threading equipment. This can be achieved by using RunFoil vacuum assisted pull down foils.
The function of RunFoil it to create a strong vacuum between the tail and the unit while paper tail is running over the unit.
The vacuum causes a pulling force which tightens the tail and simultaneously centralizes the tail to the correct position for perfect tail threading and keeps the tail away from the ropes.
