Abstract
1383209 Log slabbing machine HAWKER SIDDELEY CANADA Ltd 27 March 1972 [14 Aug 1971] 38232/71 Heading B5L A log slabbing machine, Fig. 1, comprises means for feeding a log 11 lengthwise through the machine, and a head member 16 or 17, rotatable about an axis 18.1 perpendicular to the direction of log feed. A circular saw or cutter is mounted on the inner face 23, Fig. 3, of the head member and has teeth 25 projecting outward of the periphery of the head member for cutting a slab from the log as the log is fed through the machine. Chipping knives 31 are also provided on the head member for progressively reducing the slab to chips as it is being cut from the log by the saw or cutter, the chipping knives being disposed so as to provide a chipped end face on the slab. In one embodiment, the log is fed by a roller 21, Fig. 1, and the saw comprises segments 24.1, 24.2, 24.3, Fig. 3, screwed to the end face of the member 16 in such a way that the centre, e.g. 43, of each segment is offset relative to the axis 18.1. This equalizes the extra load on the saw teeth due to the omission of teeth where the chipping knives are located. Each segment has a thicker radially inner portion and a thinner outer portion in which the teeth 25 are formed with gullets between them. Each knife 31 is trapezoidal and its cutting edge is arranged to extend into the kerf cut by the saw. In another embodiment, the saw segments 24.1, 24.2, 24.3, Fig. 3, are replaced by segments 64, 65, 66, Fig. 7, each carrying chipping teeth 68.
