A method for making a compartmentalized sealant strip and barrier assemblyhas the steps of co-extruding a barrier stripof non-sealant elastomeric material with a plurality of projecting linear extending wallsand a sealant stripwherein the sealant stripis formed on one side of the barrier stripfilling the space between the plurality of projecting wallsto form a plurality of linearly extending rows of sealantacross the transverse width of the co-extrusion to form the compartmentalized sealant strip and barrier assembly. The step of co-extruding may further include the step of: forming the projecting wallson an inclined angle relative to a plane perpendicular to the width of the assembly. The step of co-extruding further has the step of forming the barrier stripwith lateral edgesandthat extend beyond the lateral outermost sealant stripson each side of the assembly, the lateral edgesbeing bonding surfaces to seal the sealant strip and barrier assemblyinto an uncured rubber layer when assembled into an unvulcanized tire

Method and apparatus for making a compartmentalized tire sealant strip

A puncture sealant laminate for prevention of a flat tire may include three layers of sealant material separated by two layers of non-sealant material. The two layers of non-sealant material may prevent the three layers of sealant material from contacting each other and they may have first and second ends that attach to rubber in the tire that is not part of the puncture sealant laminate.
