John Dusenbery was a pioneer in the manufacture and adaptation of cutting equipment during the post World War II era of the American Industrial revolution. John Dusenbery Company machine designs included score, razor and shear slitters as well as other types of production specific slitting methods, some of which are no longer used in the converting process. These machines are commonly used in the manufacturing of textiles and nonwoven fabrics; the slitting of paper products; and conversion of film and foil materials.
