Patent ID: 6892615

Claim:
A method of sawing a relatively thick piece of wooden feed stock simultaneously into a plurality of thinner pieces of wood, comprising the steps of: (a) continuously feeding the stock from an upstream input position to a downstream output position; (b) simultaneously sawing the stock into a plurality of thinner pieces of stock as the stock is fed relative to a plurality of parallel blades by driving the blades in a reciprocating motion comprising alternate cutting and non-cutting strokes; (c) moving the reciprocating blades-alternately upstream and downstream into linearly-offset cutting and non-cutting positions relative to the stock; and (d) coordinating the reciprocating movement of the blades and the linear offset motion of the blades to thereby permit continuous movement of the stock while the blades are in both the cutting and non-cutting positions and strokes, said coordinating step including: (i) determining the reciprocation position of the blades; and (ii) moving a linear offset motion assembly which is connected to said blades linearly in timed relationship with the reciprocation of the blades.
