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.
