ABSTRACT:
A method and apparatus are provided for severing a moving thin strip material across the width of the strip by providing a thin rigid cutting element and urging the cutting element to move rapidly across the path of travel of the strip material in a plane transverse to the plane of the strip material. The strip material is contacted about one side edge and the cutting wire continues to rapidly move across the strip width from a first edge to a second edge to sever the moving strip. The method and apparatus are useful for severing strip material being produced at up to 4000 feet per minute and is not dependent upon the gauge or ductility of the material.
