Servicer for a tire building drum

A shuttle servicer comprising a carriage mounted on rails for movement between alternate positions a central frame on said carriage, aligned dispensing units projecting in cantilever fashion from each side of said central frame, the units on one side of said frame being aligned with a tire building machine in one of said alternate positions, while the units on the other side of said frame are aligned with said machine in the other alternate position, a square shaft extending parallel to said rails and journaled for rotation, and means selectively to drive said units from said shaft in any position of said carriage along said rails.

A tire component servicer comprising a stock roll, a liner take-up roll and a liner drive roll, the liner drive roll and liner take-up roll being driven, the latter through an overrunning clutch, a tail retractor positioned upstream of the liner drive roll and downstream of the stock roll operative to increase the path of the liner and stock to retract the stock and liner.

A multi-unit servicer-tire building machine combination comprising a drive motor, a drive shaft driven by said drive motor, drive means including a gear changeable transmission interconnecting said shaft and servicer, said servicer including a common drive for all units, clutch means for each unit operative to drive a selected unit from said common drive, said tire building machine comprising a drum, cooperating clutch and brake means operative to rotate said drum a predetermined extent as the clutch of the selected unit is energized, the peripheral speed of the drum and the selected unit being synchronized by said gear changeable transmission, said transmission driving a square shaft along which said servicer moves, and a sliding sprocket on said shaft driving said common drive.

A tire component servicer comprising a dispensing tray assembly including a pair of longitudinally spaced, flat, coplanar support means for the component, means to convey the tire component to said tray, centering guide means on said tray including a transverse guide rod, two carriages journaled on said guide rod for movement toward and away from each other, edge guide rolls on each carriage and movable transversely with each carriage intermediately said spaced support means, and means for urging said carriages uniformly symmetrically toward the center line of said tray.

A tire component servicer comprising means to convey the component to a dispensing tray, centering guide means for the component on said dispensing tray, said guide means comprising transverse guide rods, two carriages journalled on said guide rods for movement toward and away from each other, edges guide rolls on each carriage, a cable adjustably connected to each carriage, a sheave for each cable changing the direction thereof, and force means connected to each cable operative to pull said carriages toward each other.
