Patent number: 6695606Abstract: An extrusion apparatus for extruding visco-elastic materials includes an extruder head for preliminary shaping of a visco-elastic melt and a splice bar die assembly for final shaping of the visco-elastic melt. Both the extruder head and the die assembly have flow channels that include low elongational flow zones where elongational flow is reduced and controlled, thereby reducing and controlling the resulting shrinkage of the extrudate. Extrudate shrinkage can also be reduced and controlled by controlling the die swell of the visco-elastic melt by rotating the roller at a selected roller speed less than the melt speed.Type: GrantFiled: July 25, 2000Date of Patent: February 24, 2004Assignee: The Goodyear Tire & Rubber CompanyInventors: Gary Robert Burg, Steven John Deren, Richard David Vargo

Patent number: 6668440Abstract: A method for sequentially forming teeth in a belt that is supported on two cylinders. The method avoids having to measure the neutral plane radius by dividing the uncured belt into discrete molding sections and adjusting the length of each section prior to molding. The adjustment to the length is made so that the belt section is equivalent to a required length necessary to accommodate the proper fraction of total teeth. The first section to be molded is marked and aligned with the mold. Sequential belt sections are marked and aligned in similar fashion until teeth are molded along the entire circumference of the belt. The inventive method eliminates cumulative error by positioning each section of teeth relative to the underlying belt structure and not relative to the previous section which may have position errors within its own position tolerance.Type: GrantFiled: December 31, 2002Date of Patent: December 30, 2003Assignee: The Goodyear Tire & Rubber CompanyInventor: Douglas Bruce Wood
