A5B High Speed Small Log Debarker Features Simple fixed infeed conveyors with v-type rolls are used to feed the A5B. Nicholson auxiliary feedworks are available but not generally needed. Specially designed self-feeding and self-opening powered feedrolls are linked in pairs to automatically acquire and center the incoming log. Log gripping force is provided by powerful air cylinders located inside the debarker for protection from dirt, damage and debris. The air cylinders on the A5B hang vertically and are easy to access. A5B cylinders attach to the lower feedroll support arms and carry only the weight of the log, unlike other designs where the weight of the log and the weight of the upper roll arms passes through the feedroll linkage. The A5B’s smooth and quiet feedworks are driven by precision machined steel spur gears for maximum reliability. Continuous automatic gear lubrication is provided by a separate pump and reservoir so low cost gear oil can be used instead of debarker ring oil. Both gear and ring lube systems have fail-safe protection. The feedworks can be powered by a wide array of single or variable speed AC electric motors. Both the standard top mounted feedworks drive and an optional bottom mounted low profile direct drive is available. Heavy log restraint tunnels are standard on the A5B to make sure that even the most crooked wood flows smoothly through the debarker. In areas where it is difficult to get a wrench, we use Supernuts that are easy to tighten correctly and provide the very best security possible. It’s important details like this that have given the A5B an excellent reputation for strength and reliability.
