ABSTRACT:
A log (10) to be sawn into boards is supported by a support assembly (26) which supports the log with its longitudinal axis aligned with the direction of carriage movement of a carriage (22) reciprocating along a defined pathway. A side trimming head (12) is mounted adjacent the path followed by the log and includes first (94) and second (96) spaced-apart circular saw blades oriented so as to make two blind cuts to a predetermined depth into a supported log. An intermediate rotary cutter (104) may be provided between the blades to shape the portion of the log between the first and second blades. A third circular saw blade (14; 107), oriented transversely to the first two blades, cuts the completed board from the log.
