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.
Claims16
A profiling apparatus for profiling a log, comprising:
- a first knife having two opposite sides and a cutting edge;
- a second knife having a cutting edge;
- a mounting member adapted to receive a first side of said first knife;
- and
- a first holder adapted to apply a removable first clamping force to the second side of said first knife for clamping the knife to said mounting member, said mounting member being adapted to receive said knives so that respective tips thereof substantially abut one another, said mounting member and said first knife including corresponding mating features adapted to substantially prevent movement of said first knife with respect to said mounting member in a direction perpendicular to the cutting edge of said first knife in the event the first clamping force is reduced to zero.
A profiling apparatus for profiling a log, comprising two knives, said knives having respective cutting edges, the profiling apparatus being adapted for rotating said knives about an axis of rotation, wherein the profiling apparatus is adapted to pass said knives through an article of wood by feeding the article of wood against the knives in a feed direction perpendicular to said axis of rotation, wherein the cutting edge of one of said knives is parallel to said axis of rotation, and wherein said knives reach a point of maximum depth of penetration into the wood at which the cutting edge of the other of said knives makes a nonzero angle with a plane that is perpendicular to said feed direction.
A profiling apparatus for profiling a log, comprising two knives, said knives having respective cutting edges, the profiling apparatus being adapted for rotating said knives about an axis of rotation, wherein the cutting edge of one of said knives is parallel to said axis of rotation and the cutting edge of the other of said knives has a projection, in a plane perpendicular to said axis of rotation, that lies along a line defined by first and second points within an angular variation about said first point of about plus or minus 15 degrees, wherein said first point is defined by the tips of said knives and said second point lies on said axis of rotation.
A method for profiling a log, comprising providing a mounting member adapted for rotation about an axis and adapted to receive at least two knives, the knives having respective cutting edges, the method comprising clamping the knives to the mounting member so that the cutting edges of the knives make an angle with respect to one another and so that respective tips of the knives abut one another by applying a clamping force, and providing in the mounting member and in the knives corresponding mating features for substantially preventing movement of the knives in the direction of rotation of the mounting member in the event the clamping force is reduced to zero.
A method for profiling a log, comprising providing a mounting member adapted for rotation about an axis and adapted to receive at least two knives, the knives having respective cutting edges, the method comprising passing the knives through an article of wood by feeding the article of wood against the knives in a feed direction perpendicular to the axis of rotation, orienting the cutting edge of one of said knives to be parallel to the axis of rotation, and orienting the cutting edge of the other of said knives so that it makes a nonzero angle with a plane that is perpendicular to said feed direction when the knives reach a point of maximum depth of penetration into the wood.
A method for profiling a log, comprising providing a mounting member adapted for rotation about an axis and adapted to receive at least two knives, the knives having respective cutting edges, the method comprising orienting the cutting edge of one of the knives to be parallel to the axis of rotation and providing that the cutting edge of the other of the knives has a projection, in a plane perpendicular to the axis of rotation, that lies along a line defined by first and second points within an angular variation about said first point of about plus or minus 15 degrees, wherein said first point is defined by the tips of said knives and said second point lies on said axis of rotation.
