An apparatus and method for automated honing of elongated straight-edged cutting blades such as those used in the printing and binding industry for the trimming of books or pamphlets and the like, wherein a sharpened blade which has been ground on other equipment is thereafter registered and secured at a predetermined angle upon a moveable blade holder support of the apparatus hereof, which support is then cycled to longitudinally displace so that the blade edge is thereby brought into sequential engagement with progressively finer abrasive surfaces of a longitudinal array of cooperative upper and lower orbitally driven honing heads whereby on a single reciprocated pass therethrough the blade is efficiently finished to a smooth sharp cutting edge. In an alternate embodiment of the apparatus and method hereof it is the honing heads which are longitudinally reciprocated while the blade to be honed is held upon a stationary blade holder support.
An apparatus for automated honing of elongated straight-edged cutting blades said apparatus comprising in combination, a support frame having assembled thereto a moveable blade holder support provided with a blade set jig pivotally assembled to said support frame for registering a cutting edge of said blade, said jig cooperative with a blade register end stop at a honing head station infeed end thereof said end stop bring perpendicularly positioned to a longitudinal axis of said apparatus, a plurality of regularly spaced clamp means assembled to said blade holder support being adapted to registrably secure by means of said jig and said blade register end stop at least one sharpened straight-edged cutting blade compressivly thereto for automated honing, a pneumatic drive piston assembly for cyclicly displacing said moveable blade holder support from a place of beginning linearly along the longitudinal axis of said apparatus, a blade honing station longitudinally displaced from the place of beginning along said longitudinal axis having a cooperative plurality of orbitally driven blade honing heads adapted to sequentially engage and progressively hone a cutting edge of said sharpened straight-edged cutting blade to a finished honed state on a single longitudinally displaced cycle therethrough, and a recycle switch assembly to automatically return said moveable blade holder support to said place of beginning at the end of said single longitudinally displaced cycle.
An apparatus for automated honing of elongated straight-edged cutting blades said apparatus comprising in combination, a support frame having assembled thereto a blade holder support provided with a vertically reciprocal blade set jig cooperatively assembled to said support frame for registering a cutting edge of said blade, said jig in turn cooperative with a blade register end stop at a honing head station infeed end thereof being perpendicularly positioned to said longitudinal axis of said apparatus, a plurality of regularly spaced clamp means assembled to said blade holder support being adapted to registrably secure by means of said jig and said blade register end stop at least one sharpened elongated straight-edged cutting blade compressively thereto for automated honing, a moveable blade honing station at a place of beginning longitudinally displaced from said blade holder support linearly along the longitudinal axis of said apparatus, a cooperative plurality of orbitally driven blade honing heads comprising said blade honing station, a pneumatic drive piston assembly for cyclicly displacing said moveable blade honing station from said place of beginning along said longitudinal axis co sequentially engage and progressively hone a cutting edge of said sharpened elongated straight-edged cutting blade to a finished honed state on a single longitudinally displaced cycle thereby, and a recycle switch assembly to automatically return said moveable blade honing station to said place of beginning at the end of said single longitudinally displaced cycle.
