Abstract
An edging and curve-sawing saw has a selectively skewable sawbox, skewable to a workpiece infeed path so as to receive workpieces translated longitudinally along the infeed path and into the sawbox. The sawbox rotatably supports a saw arbor. A plurality of saw blades are slidingly mounted on the saw arbor in a parallel laterally spaced array. The saw blade array spacing is selectively adjustable device mounted to the sawbox. The array is slide on the arbor relative to the sawbox according to an optimized profile.
Claims14
An edging and curve-sawing saw for sawing a workpiece translated longitudinally in a first direction along an infeed path comprising:
- a skewable sawbox mounted in said infeed path and skewable relative to said infeed path,
- a saw arbor mounted horizontally in said sawbox, generally laterally across said infeed path,
- an array of saw blades mounted on said saw arbor,
- saw spacing means for presetting of lateral spacing between individual saw blades of said array of saw blades.
- saw translating means for active translating of said array of saw blades, in unison in a second direction, relative to said sawbox according to an optimized sawing profile,
- wherein said saw spacing means and said saw translating means are parallel rigid members,
- said parallel rigid members extending and selectively translatable in said second direction, generally parallel to said saw arbor, saw blade guides rigidly mounted to said parallel rigid members for corresponding translation with said parallel rigid members so as to selectively position said saw blades in said second direction.
In an edging and curve-sawing saw having a sawbox rotatably supporting, on a generally horizontal saw arbor, a plurality of generally vertically aligned saw blades in laterally spaced array, a method for edging and curve sawing comprising the steps of:
- (a) skewing and positioning said sawbox in a workpiece infeed path so as to receive a workpiece translated generally longitudinally along said infeed path and into said sawbox,
- (b) adjusting saw blade spacing within said laterally spaced array by adjustment means mounted to said sawbox, and
- (c) laterally translating, by saw translating means, said laterally spaced array relative to said sawbox according to an optimized profile as said workpiece is fed through said sawbox.
