Abstract
A portable sawmill system comprising at least three wheeled, independently movable modules is disclosed. The modules are independently maneuverable to a land site having a ready source of logs to be processed and are arranged in a preselected geometrical configuration adjacent one another and the source of logs. A log from the source is received on the first module and debarked. The debarked log is moved axially and transversely off the first module and onto a second module. A plurality of saw means are carried by the second module to form boards from a log being processed. A third module is located at the output side of the second module and is adapted to receive and further process the boards formed on the second module.
Claims2
A method of producing lumber from a supply of generally round logs which have bent ends, comprising the steps of:
- dropping a log on a set works so that the bent ends of the log point downwardly;
- dogging the log with its bent ends pointed downwardly;
- then rotating the set works through a pre-selected arc of approximately 45.degree. to incline the bent ends of the log from the vertical;
- and
- thereafter sawing the log into lumber.
A method of producing lumber from a supply of generally round logs which have bent ends, comprising the steps of:
- providing a set works with horizontal knee members and vertical knee members intersecting at approximately right angles to each other;
- rotating the set works through a forward arc of approximately 45.degree. about an axis perpendicular to the knee members, the knee members of the set works thus providing upwardly opening V-shaped receptacles for a log;
- dropping the log onto the receptacles of the set works so that the log assumes a position on the set works with the bent ends of the log pointing downwardly;
- dogging the log in said position;
- rotating the set works through a reverse arc of approximately 45.degree. to return the knee members to their original horizontal and vertical orientations;
- and
- thereafter sawing the log into lumber.
