Abstract
A method and apparatus for spraying a processing fluid on the internal surface of an unfinished or green tire blank. The apparatus holds the tire in a horizontal position and first grasps the upper side wall of the tire and then pulls the tire downwardly to spread it apart so that the processing fluid can be sprayed over the entire internal surface including the beaded edge. The method includes clamping the green tire in a horizontal position by its upper bead, then grasping the lower bead and pulling the tire apart to its open position where its internal surface is fully exposed and rotating the tire as the internal surface is sprayed completely, including the beaded edges.
Claims14
An apparatus for spraying processing liquid on the interior surface of green tires having inwardly inclined sides, said apparatus comprising a spreading means for spreading the green tire as well as spray means for spraying the interior tire surface, characterized in that the spreading means includes two opposite, vertically spaced rotatably mounted grasping means for clamping the tire beads in a horizontal position, the lower of said grasping means being vertically shiftable from a lower standby position into a raised operative position for grasping one of said tire beads whereby said tire bead may be pulled downwardly, in order to spread the beads, and drive means for rotating said grasping means, said spraying means being concentrically arranged within said lower grasping means and vertically shiftable between spraying and non-spraying positions.
An apparatus for spraying processing liquid on the interior surface of a green tire having inwardly inclined sides and opposite beaded edges, said apparatus comprising a spreading means for spreading the green tire and spray means for spraying the interior tire surface, said spreading means including vertically spaced rotatably mounted opposing upper and lower grasping means for grasping said beaded edges only at circumferentially spaced locations and supporting said tire in a horizontal position and about a generally vertical axis, said lower grasping means being vertically shiftable generally along said axis for grasping one of said beaded edges and for pulling said one beaded edge downwardly to spread said opposite beaded edges means supporting said nozzle within said tire while in said spaced position, and drive means for rotating said grasping means.
