Patent number: 10213975Abstract: A loader device includes a support pedestal movable over a range of longitudinal travel along a longitudinal axis, a support carriage movably mounted to the support pedestal, a loader actuator, and a dismount actuator. The support carriage is movable over a range of vertical travel along a normal axis, which is perpendicular to the longitudinal axis. The support carriage has a support arm adapted to support a tire casing. The loader actuator and dismount actuator are respectively adapted to selectively move: (1) at least a portion of a tire casing supported upon the support carriage in a loading direction along the longitudinal axis off of the support arm onto the expandable rim hub and (2) at least a portion of a tire casing supported upon the expandable rim hub in an opposing unloading direction off of the expandable rim hub and onto the support arm of the loader device.Type: GrantFiled: February 13, 2015Date of Patent: February 26, 2019Assignee: Bridgestone Bandag, LLCInventors: John S.

Publication number: 20170176175Abstract: Systems and methods of identifying and buffing tire casings are provided. A tire buffing machine includes an expandable rim, a buffer, a measurement sensor configured to generate measurement data, and a controller. The controller maintains a database of a plurality of casing profiles, where each casing profile includes known casing measurements and corresponding buffing parameters. The controller receives measurement data from the measurement sensor, identifies the casing mounted onto the expandable rim, and operates the buffer to buff the casing in accordance with buffing parameters in the matching casing profile.Type: ApplicationFiled: December 17, 2015Publication date: June 22, 2017Inventor: John S.

Patent number: 8813550Abstract: A tire inspection machine includes an incoming conveyor adapted to transport tires to the machine and also align the tires in a transverse direction. An inspection table of the machine includes a table conveyor system that is responsive to a controller. The table and table conveyor are together arranged to permit scanning of both sidewall portions of a tire disposed thereon. A sensor detects a longitudinal position of the tire and stops the table conveyor when the tire is longitudinally aligned. A controller operates the table conveyor based on the longitudinal position of the tire.Type: GrantFiled: May 31, 2013Date of Patent: August 26, 2014Assignee: Bridgestone Bandag, LLCInventor: John S. Lindsay

Patent number: 8662134Abstract: A system and method for removing an outer layer of resilient material from an object to achieve a target outer dimension includes performing an initial cut at a cutting depth to remove an outer layer of the material. A parameter indicative of a work input to a cutter that performed the cut is acquired and used to determine the cutting depth that will be used for performing a subsequent cut to remove an additional layer. In this way, subsequent cuts are performed until the target outer dimension is achieved.Type: GrantFiled: July 10, 2013Date of Patent: March 4, 2014Assignee: Bridgestone Bandag, LLCInventors: John S. Lindsay, Brian Paul Goschka
