The device can manually grind the front face of a reel type mower bedknife while the bedknife remains attached to the reel housing and can grind the front and top face of a bedknife when it is removed. It can also grind rotary type blades and a variety of other straight edged tools.

Abstract: A portable automated sharpening apparatus is structured to sharpen one or more of a plurality of blades of an operational reel blade mechanism, the apparatus including a sharpening assembly with a sharpening element movably interconnected to a sharpening motor. The apparatus also includes a drive assembly having a drive member which at least partially defines a drive path, the drive member further structured to transport the sharpening assembly along at least a portion of the drive path. A support assembly is structured to removably yet securely interconnect at least the drive assembly to the operational reel blade mechanism, and a guide assembly maintains a sharpening axis of the sharpening assembly substantially parallel to a reel blade axis. Further, the apparatus includes a control assembly to allow automatic alternation of a direction of transport of the sharpening assembly, in a reciprocating manner.

Abstract: A method for sharpening the cutting knives of a knife ring chipper, which includes a knife ring and a number of knife units, the units in turn containing knives and holding plates. The knife ring is removed from the knife ring chipper, the knife units of the knife ring chipper are removed from the knife ring and the knife units are disassembled. The dull knives are moved to a first buffer station and are stored and then moved to a grinder and sharpened. The sharpened knives are moved to a second buffer station and are stored, and the sharpened knives are then mounted onto holding plates in knife units. The knife units are incorporated into a knife ring and the knife ring is incorporated into a knife ring chipper.

Abstract: The present invention is a device for relief grinding a blade having a radially outer edge of an elongated length and first and second faces, with the first and second faces extending generally radially from a reel axis. The device includes a rotatable grinding shaft, a grinding wheel, a grinding wheel guide assembly, a guide finger, and a first non-sliding stabilizer.

Abstract: A retainer for retaining an abrasive pad on a lens making machine and an abrasive pad adapted to such retention comprises a retainer nestable with a lap of a lens making machine wherein when such retainer is nested, a pad placed upon the lap before nesting will be trapped in the desired position. The pad of the invention includes radially outwardly extending members beyond the working area of the pad whose purpose is to be trapped by the retainer. The invention enables automatic loading and unloading of pads on the lens making machine.

Abstract: A chopper drum includes a plurality of knives distributed along its width and about its circumference. A grinding device is provided for automatically sharpening the knives, with a grinding stone of the grinding device having its movement automatically controlled by a microprocessor, which receives signals from an actual shape sensor and compares it with a stored desired shape and generates control signals, such that it shapes the profile of the chopper drum to at least approximate the desired shape.

Abstract: A nozzle having a series of orifices along a longitudinal length of the nozzle for processing a substrate and which is rotatably adjustable. By the nozzle design of the present invention, liquid is properly distributed along the longitudinal length of the nozzle independently of the angle of the aerosol spray. This allows for the generation of a uniform aerosol stream that is independent of spray angle. The nozzle design of the present invention improves the uniform distribution of liquid within the nozzle, which in addition to providing a more uniform liquid pooling, also substantially eliminates temporal non-uniformities across the nozzle length. Moreover, the present invention is also directed to a nozzle that is translatable in the direction toward or away from the substrate to be processed or parallel to the substrate surface.

Further adjustment of the apparatus relative to the blades is provided by a body member mounting adjustable arms. One of the arms engages the back of the blade being sharpened, thereby providing a reliable and true reference. A second embodiment sharpens rotary saw blades while a third embodiment sharpens router and shaper bits.

Abstract: A sharpening and cleaning apparatus for sharpening scalloped-edged blades in a carton slitting machine includes at least two rotating cylindrical hones mounted on a pneumatically controlled actuator, and a pair of blade cleaning brushes mounted on a separate actuator. A sharpening operation is initiated by a machine operator as needed to maintain blade sharpness, and is performed automatically by the apparatus controls. The hone actuator positions the rotating hones in contact with opposing sides of a cutting edge of the slitting blade as the blade moves past the hones at reduced speed. A first hone is rotated in a direction opposite to the direction of the blade and a second hone is rotated in the same direction of the blade. During sharpening, the hones execute several reciprocating axial movements to stroke the blade. Prior to the operation of the hones the actuator positions the brushes in contact with the blade and causes the brushes to rotate to remove debris from the blade.
