Abstract:
1. A method of using a tire bead removing system comprising: a support frame; an elongate roller, operatively coupled with the support frame such that a length of the roller extends outwardly from the support frame; a punch arm assembly, operatively coupled with the support frame such that the punch arm assembly is positioned adjacent the elongate roller; the punch arm assembly including a punch blade operatively coupled with a punch power cylinder that, when actuated, advances and retracts the punch blade in a linear direction; and a controller, operatively coupled with the punch power cylinder, that selectively actuates the punch power cylinder and causes the punch blade to move between advanced and retracted positions; the method comprising: positioning a tire on the tire bead removing system, such that the elongate roller and punch arm assembly at least partially penetrate a central opening in the tire, the tire is at least partially supported on the elongate roller, and the punch blade is positioned adjacent a sidewall of the tire; advancing the punch blade so that it penetrates the sidewall of the tire to form a first sidewall cut; retracting the punch blade so that it fully withdraws from within the sidewall; rotating the elongate roller and the tire; advancing the punch blade so that it penetrates the sidewall of the tire to form a second sidewall cut; retracting the punch blade so that it fully withdraws from within the sidewall; repeating the steps of advancing and retracting the punch blade and rotating the elongate roller and tire until a succession of sidewall cuts free a portion of the sidewall containing a tire bead from the tire.
