  • Patent number: 4007654
    Abstract: Sawing apparatus, such as a pulpwood slasher, has an upwardly inclined, log-supporting deck provided with means to carry logs of a predetermined maximum length from the lower to the upper end thereof with the logs transversely of the deck. The deck is substantially in the form of a right triangle and its side that corresponds to the hypotenuse thereof has a series of circular saws spaced equally from each other and the ends of that side so that each log, as it is carried by the conveying means, is brought successively into engagement with the saws. The saws have a lead such that when a cut is completed, a wanted length drops onto a takeaway conveyor as it is cut free and the proximate end of the remainder of that log clears that saw as it is conveyed thereby. The takeaway conveyor extends diagonally of the path of logs and the conveying means supporting the log on both sides of each saw while it is being cut.
