Paper Drilling Machine
Operation Overview
Undrilled books are placed onto a conveyor taking them to a single spindle
drill. Each book moves down the conveyor until it reaches the first drilling
position. The conveyor stops moving and the drill lowers and drills the first
hole. The drill then retracts and the conveyor moves the same book to the
second drilling position. The drilling process is repeated until there are the
desired holes per book.
