Abstract:
A gang saw and chipper apparatus for infeed-side chipping and curve sawing of cants, the apparatus comprising:a gang saw assembly including a saw module having an infeed side and an outfeed side and a support frame upon which the saw module is moveable translationally in a first dimension and movable angularly in a second dimension for skewing the saw module relative to an infeed direction of a curved cant;a pair of chipping heads mounted in the infeed side of the saw module for translational and angular movement therewith and moveably supported in the saw module for movement transversely of the infeed direction;a pair of chipper drive motors mounted directly above the chipping heads, the motors supported by a tower independently of the saw module and positioned to rotate about a vertical axis;a pair of drive lines, each extending vertically between and drivingly coupling one of the motors and one of the chipping heads;the drive lines each including a joint which permits the chipping heads to be moved in two dimensions in a plane normal to the axes of rotation of the drive motors so that the chipping heads can move relative to the axes of the respective motors both in the first dimension with the saw module and transversely of the infeed direction and in the second dimension with angular movement of the saw module.
