Abstract
Apparatus for gripping a tire bead, moving the tire vertically and axially over an extruder nozzle die to a position within the tire chamber where a continuous extruded strip is applied to an inside surface of the tire as the tire is rotated. The extruded strip may be applied in a plurality of side-by-side turns connected by angular portions provided by axial indexing of the tire in a predetermined amount for a predetermined time. Means are also provided for spreading the tire beads and pressing the strip against the tire surface without interfering with the movement of the tire over and around the extruder nozzle die.
Claims17
Apparatus for applying a layer of extruded material to an inside surface of a tire from an extruder having a stationary extruder die for extruding a strip of said material comprising means for gripping a first bead portion of said tire, tire positioning means for moving the gripped tire into an operating position with said extruder die in close proximity to said inside surface of said tire, means for rotating said tire to lay said strip of said material on said inside surface in one turn as it is extruded from said extruder die, means for providing axial movement of said tire relative to said extruder die to lay additional turns of said strip in side-by-side relationship around said inside surface to form said layer or extruded material and said tire positioning means being reversible for moving the tire away from said extruder die so that the finished tire can be released and removed from the apparatus.
