Ball Accelerator
Mounted between the two pinsetters of a lane pair is a ball accelerator that returns balls to the bowler
from either lane. The ball enters the accelerator from the pit carpet through a ball door. A large at belt
mounted on two drums grips the ball and propels it forward to the ball lift. Refer to Figure 2-22. Power
to run the belt is furnished by a three phase motor incorporated into the rear drum.
