A double-drum wood chipper for obtaining wood chips of uniform thickness from logs. Each one of a pair of oppositely rotating, hollow, open ended drums is provided with cutting knives. An aperture through the drum walls is located near each knife for reception of the wood chips. Two knife patterns on the drums are disclosed. The parallel-cutting edge of each knife makes an angle of about 150 DEG with the cutting edge of each of two laterally positioned, integral cross cutting knives. |
