Abstract
A debarking apparatus including a closed bottom formed into a channel. A plunger is slidable in the channel and pushes bark material along the channel and out an open end of the channel. The plunger has a top surface that closes the channel as it moves through the debarking station. The bark deposited on the surface is wiped off and into the channel upon withdrawal. Preferably a shearing blade provided on the leading upper edge of the plunger shears material that protrudes above the channel opening.
