Abstract
A method and apparatus for profiling a log. In a profiler having first and second knives disposed on a rotating disc, a mounting member is adapted to mountably receive both the first and second knives so that each blade has a point on its cutting edge that is proximate a point that is on the cutting edge of the other knives. Preferably, the points are end most points and abut one another.
Claims15
A profiling apparatus adapted to rotate a plurality of cutting knives having respective cutting edges about an axis of rotation, the apparatus comprising a mounting member adapted to mount two of the knives so that the cutting edge of one of said two knives lies substantially in a plane perpendicular to said axis of rotation and within an angular variation of plus or minus 15 degrees, taken about a radially outermost first tip of said one knife, from a line extending from said first tip to said axis of rotation, and the cutting edge of the other of said two knives is parallel to said axis of rotation, and wherein said mounting member is further adapted to mount said two knives so that a tip of said other knife and said first tip substantially abut one another.
A profiling apparatus adapted to rotate a plurality of cutting knives having respective cutting edges about an axis of rotation, the apparatus comprising a mounting member adapted to mount two of the knives so that the cutting edge of one of said two knives lies substantially in a plane perpendicular to said axis of rotation and substantially on a line extending from a radially outermost first tip of said one knife to said axis of rotation.
A profiling apparatus adapted to rotate a plurality of cutting knives having respective cutting edges about an axis of rotation, the apparatus comprising a mounting member adapted to mount two of the knives so that the cutting edge of one of said two knives lies substantially in a plane perpendicular to said axis of rotation and the cutting edge of the other of said two knives is parallel to said axis of rotation, wherein said mounting member is further adapted to mount said two knives so that a tip of said other knife and said first tip substantially abut one another.
A knife for use in a wood profiling apparatus adapted to rotate the knife about an axis of rotation, the knife being adapted to be mounted in the profiling apparatus, the knife having a cutting edge defining an angle with respect to an immediately adjacent side thereof that differs substantially from 90 degrees.
A method for profiling an article of wood, comprising providing a first knife having a cutting edge, rotating the knife about an axis of rotation, orienting the knife so that said cutting edge lies substantially in a plane perpendicular to said axis of rotation, and feeding the article of wood against the knife in a feed direction perpendicular to said axis of rotation so that said cutting edge, at a point of entry of said knife into the article of wood, makes a substantially nonzero angle with respect to the direction of the grain in the article of wood.
