US 4,289,089 A · Tire sealant applicator

Abstract

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.

Apparatus for positioning a working device between the sidewalls of a tire, comprising:

a frame,
means for supporting a tire adjacent said frame;
arm means pivotally mounted to said frame for swinging movement between an advanced position adjacent one sidewall of the tire, and a retracted position remote from the tire;
carriage means reciprocatively mounted on said arm means and moveable 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 working device on said carriage means;
means for moving said arm means between the advanced and retracted positions, and
means for reciprocatively moving said carriage means between the first and second positions, whereby said working device may be positioned in the interior of the tire by moving said arm means into the advanced position and moving said carriage from the first position to the second position for locating said working device within the interior of said tire.
