Abstract
A machine for buffing worn tire casings to prepare them for retreading which includes a rotary tire casing support and a pair of powered rotary rasps engageable with a tire casing on said support, the tire casing support being movable toward and away from said rasps and the rasps being located approximately rearwardly of the tire casing support control means located at the opposite radial side of a tire casing support so that the operator can stand adjacent to one part of the tire casing support and the two rotary being located opposite to the control means. There is also a hydraulic system for moving the rasps away from each other and simultaneously actuating a template follower to allow the movement of the tire casing support and the engagement with said rasps. The rasps and template arm being swingable on pivots by a Hydraulic System, allowing the tire casing support to move through the rasps in correlation with the template arm and template, the template being movable in response to movement to the tire casing support toward the rasps. The system includes means for synchronizing the two hydraulically actuated rasps.
