Lumber edger and method of edging lumber

1. A lumber edger comprising:

a conveyor for conveying lumber;

a scanner for scanning dimensions of the lumber;

a computer in communication with the scanner;

edger saws constructed to edge the lumber; and

a positioning system constructed to position the lumber in relation to the edger saws, the positioning system comprising a plurality of positioning devices connected to the computer, each positioning device comprising a fetcher finger constructed to move between a contact position and a non-contact position, and move laterally in a direction substantially perpendicular to the conveyor using a non-hydraulic means, wherein the non-hydraulic means comprises a belt and an encoded servo motor connected to the computer, wherein at least two positioning devices are constructed to operate independently so that a first fetcher finger and a second fetcher finger can move laterally in the direction substantially perpendicular to the to contact the lumber and skew the lumber on the conveyor in relation to the edger saws.

2. A method of edge cutting lumber comprising:

conveying lumber on a conveyor;

scanning dimensions of the lumber using a scanner and sending the dimensions to a computer system;

using the computer system to determine theoretical edge cut positions on the lumber;

providing a positioning system constructed to position the lumber in relation to edger saws so that the edge saws cut the lumber at the theoretical edge cut positions, wherein the positioning system comprising a plurality of positioning devices connected to the computer, each positioning device comprising a fetcher finger constructed to move between a contact position and a non-contact position, and move laterally in a direction substantially perpendicular to the conveyor using a non-hydraulic means, wherein the non-hydraulic means comprises a belt and an encoded servo motor connected to the computer, at least two positioning devices being independently controlled by the computer system, the at least two positioning devices comprising a first positioning device comprising a first fetcher finger and a second positioning device comprising a second fetcher finger;

moving the first and second fetcher fingers into the contact position;

laterally moving the first and second fetcher fingers so that the first and second fetcher fingers contact the lumber and skew the lumber to line up the theoretical edge cut positions with edger saws; and

cutting the lumber using the edger saws at the theoretical edge cut positions to provide a board.

3. The lumber edger according to claim 1 , wherein the positioning system is constructed to simultaneously position the lumber on the conveyor in both a transverse direction and skew direction on the conveyor in relation to the edger saws.

4. The method according to claim 2 , further comprising laterally moving the fetcher fingers in the contact position to simultaneously position the lumber in both the skew direction and a transverse direction on the conveyor to line up the theoretical cut lines with the edger saws.

5. The method according to claim 2 , wherein the fetcher finger is constructed to rotate between a contact position and a non-contact position and the method further comprising rotating the first and second fetcher fingers into the contact position.

6. The lumber edger according to claim 1 , wherein the fetcher finger is constructed to rotate between a contact position and a non-contact position.
