Publication number: 20090173199Abstract: A method and apparatus is provided for cutting an elastomeric laminate that may include a layer of reinforcement cords, into a desired length without cutting through the cords. The method includes the step of cutting through the gum portion of the elastomeric composite material at a desired skive angle, and then opening up the skived cut. Next, the cord reinforcement layer is cut without severing the reinforcement cords. An elastomeric composite strip cut to the desired length is produced and has cut ends. One of the cut ends has the gum portion cut at a desired skive angle adjacent an overhang portion of the reinforcement layer. The opposite end of the elastomeric composite segment also has a skived portion to mate with the skived portion of the first cut end, and a gap in the cord ply to mate with the cord overhang of the first end, resulting in a splice. An improved anvil having independently controlled vacuum zones is also provided, as well as improved cutting mechanisms.Type: ApplicationFiled: March 18, 2009Publication date: July 9, 2009Inventors: Daniel Ray Downing, David Michael Dejacimo, Dennis Alan Lundell, Steven Leonard Kitz, Mark Alan Thompson

Patent number: 7189298Abstract: Method for providing precured innerliners (50) having a predetermined cross sectional profile for use as part of a pneumatic tire assembly used in a bladder-less shaping and vulcanizing mold. The innerliner (50) is formed from a continuous strip of elastomeric material (12) hot formed using a calender assembly (10) with a profiled calender roller (16). The formed strip is cured “in-line” in a press (38) having a profile matching platen (80) before being wound onto a tire building drum (48). After the pneumatic tire assembly is completed, the assembly is shaped and cured in a bladder-less mold, utilizing the precured innerliner as the impervious inner layer. Initially, the center region (62) of the innerliner is at least twice as thick as the lateral regions (72, 74). In the finished pneumatic tire, the innerliner exhibits a uniform thickness.Type: GrantFiled: November 25, 1998Date of Patent: March 13, 2007Assignee: The Goodyear Tire & Rubber CompanyInventors: Albert James Yovichin, Daniel Ray Downing, James Alfred Benzing, II
