An apparatus for adjusting a knife edge offset in a cutter toolhead having a cutter toolhead frame. The apparatus including a knife moveably coupled to the toolhead, an actuated arm moveably attached to the cutter toolhead frame, a computer controller for controlling the movement of the knife and actuated arm, an abrasive sharpener moveably attached to the actuated arm and adapted to contact the knife, and a sensor adapted to determine a distance between the cutter toolhead frame and the actuated arm. The computer controller of the apparatus is further capable of adjusting the movement of the knife and the actuated arm as a function of the distance determined by the sensor.

A cutting apparatus includes a processing feed direction determining mechanism. The processing feed direction determining mechanism includes an imaging unit that images a region including a cut groove and a recording unit that records chipping data of the imaged cut groove. The recording unit records first chipping data of a cut groove formed by cutting a workpiece from a first direction, second chipping data of a cut groove formed by cutting the workpiece from a direction opposite from the first direction, third chipping data of a cut groove formed by cutting the workpiece from a second direction orthogonal to the first direction, and fourth chipping data of a cut groove formed by cutting the workpiece from a direction opposite from the second direction.

Various embodiments of systems and methods facilitate the calibration of a printer. The printer can print a calibration target and cut the calibration target using an inline slitter. The printer can determine a calibration offset based on the position of the cut on the calibration target. The printer can then be calibrated according to gross amounts on the slitter and fine amounts at an ink applicator.

A printer includes: a conveyor; a printing device; a roller; a moving mechanism configured to move a moving member; and a cutter that performs a cutting operation. A controller executes: a printing processing for performing a printing operation while conveying the printing medium with the moving member being located at a second position; a cutting processing for performing the cutting operation after the printing operation is stopped; a moving processing for controlling the moving mechanism such that movement of the moving member to a first position is completed before the cutting operation; and a roller driving processing for, after the movement of the moving member to the first position is completed and before the cutting operation, rotating the roller in a direction for conveying the printing medium downstream in a conveying direction and stops the roller from rotating.

A cutting apparatus includes a processing feed direction determining mechanism. The processing feed direction determining mechanism includes an imaging unit 28 that images a region including a cut groove and a recording unit that records chipping data of the imaged cut groove. The recording unit records first chipping data of a cut groove formed by cutting a workpiece from a first direction, second chipping data of a cut groove formed by cutting the workpiece from a direction opposite from the first direction, third chipping data of a cut groove formed by cutting the workpiece from a second direction orthogonal to the first direction, and fourth chipping data of a cut groove formed by cutting the workpiece from a direction opposite from the second direction.

A slitter device comprising a circular blade at an outer periphery of the slitter device. One or more row of transverse blades at the outer periphery and on a side of the circular blade, the blades of the row of transverse blades being oriented transversely relative to the circular blade.

A cutting apparatus includes a cutting liquid supply nozzle disposed adjacent to a cutting unit, for supplying a cutting liquid to a point of contact between a cutting blade and a workpiece, and a rust inhibitor supply nozzle for supplying a rust inhibitor to the workpiece to prevent electrodes of devices divided from the workpiece from being rusted, the rust inhibitor supply nozzle having a length along a Y-axis in excess of the width of the workpiece along the Y-axis.

An apparatus for adjusting a knife edge offset in a cutter toolhead having a cutter toolhead frame. The apparatus including a knife moveably coupled to the toolhead, an actuated arm moveably attached to the cutter toolhead frame, a computer controller for controlling the movement of the knife and actuated arm, an abrasive sharpener moveably attached to the actuated arm and adapted to contact the knife, and a sensor adapted to determine a distance between the cutter toolhead frame and the actuated arm. The computer controller of the apparatus is further capable of adjusting the movement of the knife and the actuated arm as a function of the distance determined by the sensor.

A cutting liquid supply unit of a cutting apparatus includes a pair of gutter forming nozzles that are disposed to face each other in such a manner as to sandwich a cutting blade and that supply a cutting liquid to the cutting blade to form gutters extending in a processing progression direction, and a tip nozzle that supplies the cutting liquid from the outer circumferential side of the cutting blade toward the cutting blade on the upstream side in the processing progression direction. The tip nozzle supplies the cutting liquid toward a processing point at which the cutting blade cuts into a workpiece, and guides the cutting liquid by the gutters toward the downstream side in the processing progression direction.

The exemplary embodiments relate to a circular blade (1) having two end faces (2) and a peripheral cutting edge (3). The blade includes two axial sides (12, 14). In at least one axial side at least one material tapering (4) is formed running concentric to the cutting edge (3), so that a thickness of the circular blade (1) decreases radially outwardly towards a minimum tapering thickness (5) due to the geometric formation of the material tapering (4). The minimum tapering thickness (5) is dimensioned so that the circular blade (1) cannot be broken at the material tapering, so that a successor cutting edge can be produced by grinding only in the region of the material tapering.
