  • Method and apparatus for preparing ceramic body segments
    Patent number: 9987766
    Abstract: A method including providing a ceramic log (300) with a first end and an opposing second end; providing one or more cutting devices (100) comprised of a dual bladed cutting member (200); and removing material by cutting at least the first end with the dual bladed cutting member (200), wherein a first blade (210) of the dual bladed cutting member (200) provides a finished surface and a second blade (220) removes a percentage of scrap above the finished surface. An apparatus (100) for cutting a ceramic log (300).

  • APPARATUS AND METHOD FOR CUTTING FORMABLE AND/OR COLLAPSIBLE MATERIALS
    Publication number: 20150239140
    Abstract: Extrudate 10 materials that are in a formable and/or collapsible state present multiple challenges for cutting into lengths, particularly when the extrusion profile Includes one or more openings 12 (e.g., running the length of the extrudate 10). The invention is directed at apparatus, devices, systems and methods for cutting the extrudate 10. A cut 64 (e.g., and initial cut) into the extrudate 10 is performed using an ultrasonic knife 27 that vibrates at one or more frequencies. Preferably the cut using the ultrasonic knife 27 is a partial cut 64. A further cut through the extrudate 10 may be made using a secondary cutting tool such as a wire cutter 68. The secondary cutting tool preferably creates a final cut 66 through the extrudate profile, for cutting a part to a length. The ultrasonic knife 27 preferably travels In the horizontal direction at a rate faster than the extrudate 10 while cutting.
