  • Method and apparatus for monitoring and inspecting rotary knives
    Patent number: 5926558
    Abstract: 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 strip edge
    Patent number: 5857031
    Abstract: 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 measuring the width of metal strip
    Patent number: 5768154
    Abstract: 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.
