Abstract:
1. An apparatus for cutting a log, the apparatus comprising: a plurality of rotational drive devices; a plurality of drive shafts, wherein each drive shaft is a rotationally separate member from the other drive shafts, and each drive shaft is operably connected to a respective one of said drive devices; a plurality of cutting blades, at least two of said blades being operably connected to each of said drive shafts, each of said cutting blades being moveable between first and second positions such that said cutting blades in the second position are configured to cut the log in a cutting position, each cutting blade operably connected to a respective one of said drive shafts being configured to be moved to the second position while at least one of said blades operably connected to the respective drive shaft is in the first position such that the log in the cutting position is cut by less than all of the cutting blades operably connected to each of said drive shafts; and a plurality of arms rotatable relative to said drive shafts, each cutting blade being mounted on a respective one of said arms such that rotating each arm moves the respective cutting blade between the first and second positions, wherein said cutting blades are configured at consecutive positions in a direction generally parallel to a centerline of the log in the cutting position with a nominal distance of 2 feet between adjacent cutting blades.
