ABSTRACT:
A method and apparatus for severing a length of insulating batting and simultaneously cutting only the insulating material thereof is provided. The insulating material between the severed edge of the insulation batting and the cutting line through the insulating material can be removed to expose a length of backing which can be secured to the uncut portion of the insulation batting length when the insulation batting length is wrapped around a length of a heating and cooling duct or the like. The apparatus includes a pair of rotating cutting wheels rotatably mounted on a carriage movable along an elongate carriage rail. A pinion gear mounted to each rotating cutting wheel for rotation therewith meshes with a rack secured to the elongate carriage rail to cause rotation of the rotating cutting wheel in response to movement of the carriage along the carriage rail.
