Publication number: 20220402228Abstract: Disclosed herein, a tire tread cutting apparatus for cutting a length of a tire tread is described. The tire tread cutting apparatus includes a track having a first track end and a second track end downstream of the first track end. The track includes a plurality of rollers positioned between the first track end and the second track end. The plurality of rollers is configured to facilitate the tire tread along the track. A tire hub is positioned downstream of and adjacent to the second track end. The tire hub is configured to receive a tire casing. The tire casing defines a tire casing circumference along an outer surface of the tire casing. A tread dispenser is positioned upstream of the track and configured to dispense tire tread. The tread dispenser includes a drive roller configured to drive tire tread downstream toward the second track end.Type: ApplicationFiled: November 4, 2020Publication date: December 22, 2022Applicant: BRIDGESTONE BANDAG, LLCInventors: Robert P. Hardy, Eric M. Henriksen, Aaron M. McCombs, Zachary A. Milliron, Jeremiah J. Nartker, Jeffrey A. Wachtel, Merle R. Schlapkohl

Patent number: 10786961Abstract: A rim for mounting a tire includes a base portion and a rim portion. The rim portion includes a rim segment, a first flange segment positioned on one side and a second flange segment positioned on an opposite side of the rim segment. The rim segment defines a circular curvature and has an original rim width measured along a rotation axis of the rim between inward facing surfaces of the first flange segment and the second flange segment. A band is positioned around a circumference of the rim segment contiguous with an inward facing surface of the first flange segment. The rim portion has an adjusted rim width, measured between a band inward facing surface and the inward facing surface of the second flange segment, which is different from the original rim width.Type: GrantFiled: July 31, 2017Date of Patent: September 29, 2020Assignee: Bridgestone Bangag, LLCInventors: Eric M. Henriksen, Noel K. Stineman, Wade L. Terrill, Matthew S. Bartenhagen

Patent number: 10261038Abstract: A tire inspecting apparatus for a tire is provided. The apparatus includes a test stand for supporting and rotating a tire. The test stand is configured such that a tire supported thereon defines a center axis. The apparatus includes a testing probe configured as a high voltage electrode for generating an electric field and a grounding element. A positioning assembly includes a support bracket and a positioning arm supporting the testing probe. The positioning arm is operable to move the testing probe into a working position between the sidewalls of a tire supported on the test stand and in proximity to the grounding element. The positioning arm is connected to the support bracket for pivoting movement relative to the support bracket about a pivot axis. The pivot axis extends at a non-perpendicular angle relative to the center axis of a tire supported on the test stand.Type: GrantFiled: December 14, 2015Date of Patent: April 16, 2019Assignee: Bridgestone Bandag, LLCInventors: Troy A.
