Abstract
A debarking/delimbing apparatus and method wherein logs are continuously handled by a stem hauling skidder continuously throughout the debarking/delimbing operation. The debarking/delimbing apparatus is provided with a side loading entry into the debarking/delimbing flails including a ramp or feed rollers for lateral ramping or feeding of tree stems up and through the side entry. A skidder-type stem hauler skids the tree stems toward the infeed entry, then tightly swings around the apparatus. The tree stems are swung out to the side of the apparatus and then back into the ramp to be ramped laterally into the flails. The skidder turns back to the infeed direction of travel to pull the tree stems in the conventional direction through the flails.
