Patent number: 7963018Abstract: A method and apparatus is provided for separating two or more annular members such as bead assemblies or bead and apex assemblies. First, a flexible member is inserted into the annulus of the annular members. Next, the flexible member is inflated until the outer surface of the flexible member contacts the inner diameter of the annular member.

Patent number: 7094456Abstract: A hybrid liner (40) and system for using a hybrid liner includes a first portion (42) being made of one material and a second portion (44) being made of a separate material. The two materials have a different propensity for sticking to the unvulcanized rubber component (20) as well as a different cost. The invention concerns using the less sticky, more expensive liner in the areas of the liner roll where sticking is more likely to occur and using the less expensive material where liner to rubber adhesion is less of a problem.Type: GrantFiled: June 1, 1998Date of Patent: August 22, 2006Assignee: The Goodyear Tire & Rubber CompanyInventors: Richard David Vargo, Charles Terry Huffstetler

Publication number: 20040089400Abstract: A method and apparatus 100 for forming an annular elastomeric tire component has the steps of extruding at least one elastomeric material annularly onto a support surface 60 and shaping the at least one strip 2 of elastomeric material to a predetermined profile by forming the at least one strip 2 of material between a shaping die 84 and the support surface 60 thereby smoothing and spreading the strip to the desired profile. The method may include applying additional strips 2 to form multilayered components. The support surface 60 may be separate from a tire building station 200 or may be integral to a tire building station 200. The formed strips may include any one or more tire components such as a sidewall 20, a chafer 30, a bead apex 10, ply stock coatings 40, an innerliner 50, or a tread 22.Type: ApplicationFiled: November 8, 2002Publication date: May 13, 2004Inventors: Richard David Vargo, Gary Robert Burg, Brian Richard Koch, Mark Anthony Sieverding

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: 6402077Abstract: The present invention is directed to a winding bay and a method of winding to provide for a high quality wind of a viscoelastic material. A viscoelastic material and a supporting liner are wound onto a roll. After unwinding the liner from a liner let-off roll, the liner is guided under high tension. Before guiding the viscoelastic material onto the liner, the tension in the liner is isolated to reduce the tension in the liner. The viscoelastic material is guided onto the liner, and the viscoelastic material and the supporting liner are wound onto a windup roll.Type: GrantFiled: February 14, 2001Date of Patent: June 11, 2002Assignee: The Goodyear Tire & Rubber CompanyInventors: Richard David Vargo, Robert Henry Vogliano

Patent number: 6330024Abstract: A quantity of material contained in a bank between a pair of calendering rolls is determined by digital imaging technology. Manipulation of digital images provided by a camera yields a light-hued image of material in the bank against a dark-hued background. The light-hued image is then divided into control zones associated with discrete regions of the bank fed by separate feed lines. Quantity and distribution of material in the bank can be controlled by adjusting feed rates based on information obtained through the digital images.Type: GrantFiled: December 4, 1998Date of Patent: December 11, 2001Assignee: The Goodyear Tire & Rubber CompanyInventors: Richard David Vargo, Harlan William Frerking, Jr.
