Starting from a loading position, a door carriage moves a door sideways between a pair of saws to trim the ends of the door. Then the carriage remains stationary while a pair of planer heads move across the carriage to trim the side edges of the door. Finally, in a lower path of travel, the carriage returns to its loading position for unloading the door, with the door passing with clearance under the saws. During these operations the door is secured by a vacuum table on the carriage.
