Abstract

A system permits the apparatus for slicing veneer from a flitch to be initially adjusted and to be operated efficiently and reliably. The system includes an improved pressure plate adjustment means as part of the apparatus, including an electric drive for each end of the pressure plate to quickly and accurately position the pressure plate relative to the edge of the veneer cutting blade. By simply pressing push buttons controlling the two electric drives, each end of the pressure plate can be caused to move forward or backward in precise increments of less than 0.001 inch and to be quickly and accurately vertically aligned with the cutting blade edge. Thereafter, the desired spacing can be set on a control console by means of thumbwheel switches and a computer means will automatically position the pressure plate to achieve the desired spacing. The system further includes a blade advance means which effects both the movement of the cutting blade away from the flitch prior to each return stroke of the flitch table, and toward the flitch table to be positioned for accurate slicing of each layer of veneer during each slicing stroke. The blade advance means includes a separate electric motor drive coupled to the carriage and controlled from the control console from which veneer thickness can also be set. By simply setting the veneer thickness on the console, the electric motor drive will automatically advance the carriage, and the cutting blade supported thereon, forward by the desired distance following each slicing operation to position the blade relative to the flitch for the next slicing operation.
