Abstract
A method for spraying a processing fluid on the internal surface of an unfinished or green radial tire blank includes clamping the green radial tire in a horizontal position by grasping its upper beaded edge, then grasping its lower beaded edge and pulling the tire apart to its open position where its internal surface is fully exposed, and effecting relative rotation between the tire and a fluid spraying device as the internal surface is sprayed completely, including the beaded edges.
Claims4
A method for spraying a processing liquid on the interior surface of a green radial tire, said green radial tire having flexible sides and beaded edges around internal edges of said sides, said method comprising:
- positioning said green radial tire in a horizontal position whereby said green radial tire has an upper and a lower beaded edge;
- charging a first grasping device having spreadable grasping elements with said tire by grasping the upper beaded edge of said tire at spaced apart locations;
- conveying said first grasping device to a position above and oppositely facing a second grasping device having spreadable grasping elements;
- grasping the lower beaded edge of said tire at spaced apart locations with said second grasping device;
- vertically separating the upper and lower beaded edges by pulling on the upper and lower beaded edges;
- and
- spraying the interior tire surface.
A method for spraying a processing liquid on the interior surface of a green radial tire, said green radial tire having flexible inwardly inclined sides and beaded edges around internal edges of said sides and comprising the steps of positioning said green radial tire in a horizontal position so as to position one of said beaded edges in an upper position and the other of said beaded edges in a lower position,
- charging a first grasping device having spreadable grasping elements with said tire by grasping the upper beaded edge of said tire at spaced apart locations;
- conveying said first grasping device to a position above and oppositely facing a second grasping device having spreadable grasping elements,
- grasping the lower beaded edge of said tire at spaced apart locations with said second grasping devices and pulling said lower beaded edge downwardly thereby vertically separating said beaded edges from one another whereby said interior surface is unobstructed, positioning a processing liquid spraying means within said green radial tire and between said beaded edges, spraying said interior surface with a processing liquid, and causing relative motion between said spraying means and said green radial tire whereby the entire inner surface of said green radial tire including said beaded edges are covered with processing liquid.
