An improved method for applying an annular tread ( ) to a pneumatic tire casing ( ) which has the steps of mounting the tread ( ) on a tread expander assembly ( ) wherein the tread ( ) pass over a mount wheel ( ) prior to the casing ( ) being mounted onto the mount wheel. The improved apparatus ( ) has all the mechanisms for supporting the casing ( ) and the tread ( ) extended from one end ( ) allowing the operator to work entirely in front of the apparatus.

Method and apparatus for measuring the thickness of rubber over a metal

A method and apparatus for buffing a tread is described. The method comprises mounting a tread on an apparatus capable of bufffing the casing engaging surface of said tread, the apparatus buffing the tread such that the grooves are formed on the buffed tread surface. The grooves angularly intercept a tread edge.

Tread buffing apparatus

A method and system for retreading tire carcasses (10) with precured treads utilizing time and temperature in conjunction with an envelope pressure system. A precured rubber tread (12), is applied to tire carcass (10) having a cushion gum (16) disposed therebetween. An envelope system is placed over the tread/carcass and this assembly is placed within a pressure chamber. Heat and fluid pressure are then supplied to the chamber. Fluid pressure is then supplied to the chamber after both a predetermined length of time and after a predetermined temperature of the chamber has been reached.
