ABSTRACT:
A chipper infeed spout incorporating two surfaces disposed to form a V-shape having one side formed by a pair of support means (an anvil member and preferably a roll). A driven power roll is moveable across the direction of travel of the log along said spout and tends to align the log and force it against the pair of support means whereby the log forms a beam freely supported (by the support means) and having a concentrated load (power roll) interposed between the supports. Preferably the power roll is oriented to apply forces to a log not only to tend force it against the two spaced supporting means but also to force it toward the apex of the V of the V-shaped supporting surfaces. When the chipper is used as a slab chipper it is preferable to form one of the support means by a driven roll that is arranged at an angle and driven in a direction to tend to lift the side of the slab that contacts the roll whereby the movement of the power roll tends to align the major dimension of the slab flat against roll and thus the anvil number.
