The applicator includes two elongated conveyor rollers arranged in parallel alignment and inclined from a sealant application station toward a tire unloading station. The rollers simultaneously rotate a series of tires in the same direction about a common axis in side-by-side engagement with one end tire adjacent the sealant application station and the other end tire adjacent the unloading station. A kicker assembly unloads the latter end tire, whereupon the rollers advance the remaining tires toward the unloading station while maintaining coaxial rotation thereof. A fresh tire then may be positioned at the application station and the application and advancement steps repeated. The applicator further includes a sealant applicator for effecting airless spray application of sealant to a tire, together with a control system for controlling the position of the spray applicator and causing sealant to be purged a predetermined time after no sealant application is made. The applicator is suited for usage in a system for producing self-healing tires.

An apparatus for positioning a sealant application device in the interior of a tire comprising: a frame; tire support means located adjacent said frame for supporting and rotating a tire; arm means pivotally connected adjacent one end thereof for swinging movement between an advanced position wherein it is generally perpendicular to the axis of rotation of said tire and a retracted position remote from said tire; means attached to said frame for engaging and positioning said arm when it is in said advanced position; carriage means mounted on said arm means between said pivotal connection and said stop means for reciprocative movement along said arm means between a first position removed from the tire interior and a second position proximate to the tire interior when said arm means is in the advanced position; means for mounting said sealant application device on said carriage means; tire spreading means mounted on said carriage means for spreading the beads of a tire apart when said carriage means is in the second position; first actuator means for moving said arm means between said advanced and retracted positions; and second actuator means for moving said carriage between said first and second positions, whereby said sealant application device may be inserted into the interior of a tire by movement of said arm means into its advanced position followed by movement of said carriage means from its first position to its second position.
