  • Patent number: 6330895
    Abstract: A log flaking and loading method and apparatus. First and second pairs of cutting heads have cutting heads spaced apart to receive a log passed therebetween and thereby to cut two substantially parallel sides. The log is first cut by the first pair of cutting heads, rotated about its elongate axis, and cut by the second pair of cutting heads to produce a four-sided cant. The logs are preferably stored ahead of the first pair of cutting heads in corresponding carriers, which are preferably held in a magazine for dispensing the loaded carriers.
