A metal shearing tool demonstrating improved fatigue life having a body; an edge of the body having a first surface and a second surface; a cutting surface disposed between the first surface and the second surface. The edge has a substantial absence of finish marks substantially parallel with the cutting surface on all surfaces of the edge, and at least one of a curved profile surface and a radiused cutting surface.

Shear knife

A metal shearing tool demonstrating improved fatigue life having a body; an edge of the body having a first surface and a second surface; a cutting surface disposed between the first surface and the second surface. The edge has at least one of a curved profile surface, a radiused cutting surface, and a substantial absence of finish marks substantially parallel with the cutting surface on all surfaces of the edge.

A design tool for predictively indicating, in metal slitting, expected edge conditions of slit metal. Also contemplated is a corresponding method. Further contemplated is a design tool and method for providing, in metal slitting, a predictive assessment of at least one condition relating to at least one of: knife edge and slit metal edge.

Design tool for predictively indicating edge conditions in metal slitting

A spacer element having a first material and at least one second material. The at least one second material has a specific gravity less than that of the first material, and the first material is integrated with the at least one second material. Also contemplated is a rotary knife arrangement having such a spacer element.

Spacers in and for cutting devices

A method of monitoring and inspecting one or more operational characteristics of a knife includes providing at least one image producer having a field of view that substantially frames the knife, using the at least one image producer to form a first series of images of the knife while the knife is in use, and analyzing the first series of images to determine whether the one or more operational characteristics of the knife are within one or more preliminary operating parameters.

Method and apparatus for monitoring and inspecting rotary knives

A method of monitoring and inspecting an edge of strip metal includes providing at least one image producer having a field of view that substantially frames the edge, using the at least one image producer to form a first series of images of the edge after the edge has been formed by a knife; and analyzing in real time the first series of images to determine the shear angle and/or the burr height of the edge.

Method and apparatus for monitoring and inspecting strip edge

A method of monitoring a dimension of strip stock formed by a cutting device includes: providing an image producer that is movable between a home position and at least one subsequent position associated with the strip stock; moving the image producer to the at least one subsequent position where the field of view of the image producer substantially frames the strip stock dimension to be monitored; forming a first image of the strip stock dimension; and analyzing the first image of the strip stock dimension to determine the length thereof.

Method and apparatus for measuring the width of metal strip

A computer design tool for determining a predictive indication of slit width variation to adjust an arbor setup in rotary slitting of metal in accordance with the indication of slit width variation. A method of using such a design tool is also provided. The design tool performs an analysis on historical slitting runs to provide the predictive indication of slit width variation.
