Patent number: 6619573Abstract: A chopper for chopping items such as fibers, fiber strands, ribbon, etc. by passing the items continuously in a loose, unwound, condition through the nip of a blade roll and a backup roll having a working layer on its outer periphery. The chopper of the present invention uses one or more rolls that are radially expandable and retractable to replace the blade roll and/or the backup roll on the prior art choppers so that worn blades and/or a worn working layer can be more quickly and more easily replaced with a new or repaired working layer or blade holder containing sharp blades. The chopper of the present invention eliminates the need to carry large, heavy, awkward rolls through the fiber forming rooms or areas where the items are being chopped and also to transport such rolls back and forth to the location where they are being rebuilt.Type: GrantFiled: August 22, 2001Date of Patent: September 16, 2003Assignee: Johns Manville International, Inc.Inventors: Russell Donovan Arterburn, Randall Clark Bascom

Publication number: 20030167889Abstract: A chopper for chopping fibers or fiber strands having a back up roll and a blade roll containing blades that work against a peripheral surface of the back up roll and a method of using is disclosed. The chopper has a number of improved features for reducing the frequency of long fibers or long fiber strands and fuzz from getting into the chopped product. The chopper can have one or any combination of the improvements. The improvements include a strand guide located at least two feet up stream of the chopper, a first starting roll for starting a new strand that runs on a fluid bearing that can be adjusted to control the RPM of the first starting roll, a mount for a roll that runs against the peripheral surface of said back up roll, a strand guide insert for reducing fuzz generation and for preventing fuzz from getting into the product, and a deflector plate for catching and deflecting chopped strands thrown off the back up roll into a chopped strand product chute.Type: ApplicationFiled: March 10, 2003Publication date: September 11, 2003Applicant: Johns Manville International, Inc.Inventors: Randall Clark Bascom, Harold Miles Hendrickson, Russell Donovan Arterburn, Carlos Gilberto Santizo, Emery Sidney Barber

Patent number: 6453702Abstract: A fiberizing apparatus for converting molten material into continuous fibers having an improved internal support structure to minimize high temperature creep and sagging of the tip plate or orifice plate is disclosed. The preferred internal support structure is welded to the sidewalls and the top surface of the tip plate and is comprised of a plurality of internal intersecting supports that form a diamond shaped structure. A method of fiberizing a molten material using the fiberizing apparatus is also disclosed.Type: GrantFiled: September 29, 2000Date of Patent: September 24, 2002Assignee: Johns Manville International, Inc.Inventors: Terry Joe Hanna, Russell Donovan Arterburn, James Melvin Higginbotham
