ABSTRACT:
The present invention provides a feeder apparatus for timber harvesters, said apparatus being intended to pull the log in for trimming and preferably featuring a three strand roller chain rotating around a turning wheel and a cog wheel with log grabbing members attached to the outer plates to the roller links of the roller chain. It is the intention of the present invention to realize a track-operated feeder apparatus simpler yet sturdier than conventional designs. In a feeder apparatus in accordance with invention, the chain is powered by a cog wheel driving the center strand of roller links, and all strands of roller links are supported essentially for a grab length sufficient to provide a firm contact to the logs by rolling beds supporting the rollers.
