ABSTRACT:
An improved trimmer section is provided for use in a sawmill, together with method and means for automatically selecting timbers and the like to be trimmed, and for automatically routing trimmed timbers to a preselected one of a plurality of different storage and loading points in the sawmill. In particular, the operator is required to select which of several stations is to receive each timber after it has been cut to a designated length. Thereupon, the timber is automatically transferred through several stages of mechanical manipulation to the designated station while, simultaneously therewith, another un-trimmed timber is promptly conducted to the trimming saws. Actuation of the entire operation is effected by merely selecting the station to receive the trimmed timber, since the cycle will repeat as long as there are timbers to be trimmed.
