ABSTRACT:
A vacuum holding device is provided for a veneer slicer, comprising a vacuum source, a platen having a flat surface comprising a plurality of vacuum compartments, wherein each compartment contains at least one port connected through a vacuum line to the vacuum source, sealing means within each compartment, wherein the sealing means surrounds each compartment and also extends outwardly from the compartment beyond the flat surface of the platen such that a flitch to be sliced contacts the sealing means when the flitch is moved proximate the platen, wherein the compartment, sealing means and flitch create a vacuum chamber which holds the flitch in place during slicing; and, a ball valve connected in each vacuum line between each port and the vacuum source, wherein each ball valve is operatively arranged to open to create a vacuum to exist in its respective compartment.
