Abstract
A machine-driven saw blade including (1) a blade body having a blade body edge with a plurality of primary saw teeth for cutting during blade movement in a first direction, the primary teeth spaced at a primary tooth pitch and each having a primary tooth tip and primary-tooth leading and trailing edges and (2) at least one secondary saw tooth on the trailing edge of a subset of primary saw teeth, the at least one secondary saw tooth having a secondary tooth tip and a secondary-tooth leading edge configured for cutting during blade movement in a second direction opposite the first direction.

A machine-driven saw blade comprising:
- a blade body having a blade body edge including a plurality of primary saw teeth for cutting during blade movement in a first direction, the primary teeth spaced at a primary tooth pitch and each having a primary tooth tip and primary-tooth leading and trailing edges;
- and
- at least one secondary saw tooth on the trailing edge of a subset of primary saw teeth, the at least one secondary saw tooth having a secondary tooth tip and a secondary-tooth leading edge configured for cutting during blade movement in a second direction opposite the first direction.
A machine-driven saw blade comprising a blade body with a blade body edge having:
- a plurality of primary saw teeth for cutting during blade movement in a first direction, the primary teeth spaced at a primary tooth pitch and each having a primary tooth tip;
- and
- at least one secondary saw tooth located between a subset of adjacent primary saw teeth, the at least one secondary saw tooth having a secondary tooth tip and a secondary-tooth leading edge configured for cutting during blade movement in a second direction opposite the first direction.
A sawmill system comprising:
- a cutting saw including a saw blade having:
- a blade body having a blade body edge including a plurality of primary saw teeth for cutting during blade movement in a first direction, the primary teeth spaced at a primary tooth pitch and each having a primary tooth tip and primary-tooth leading and trailing edges;
- and
- at least one secondary saw tooth on the trailing edge of a subset of primary saw teeth, the at least one secondary saw tooth having a secondary tooth tip and a secondary-tooth leading edge configured for cutting during blade movement in a second direction opposite the first direction;
- at least one material sensor for sensing the presence of a foreign object within a workpiece prior to the blade engaging the foreign object and configured to transmit a signal indicating said presence;
- and
- computer-based processing apparatus configured to receive the signal and to control movement of the saw blade in response thereto.
