Abstract: A method and system for applying a sealing agent to a surface (2) of an inner cavity (3) of a pneumatic tyre; the method provides for detecting the weight of the pneumatic tyre (4) before and after the application of the sealing agent to the surface (2); calculating the difference between the quantity of sealing agent applied to the surface (2) and a reference quantity of sealing agent, storing said difference within a short-term memory buffer (24) and a long-term memory buffer (26); determining a short-term compensation factor (KST) and a long-term compensation factor (KLT) and calculating a correction factor (KEA) using alternately the short-term compensation factor (KST) or else the long-term compensation factor (KLT); and using said correction factor (KEA) to actuate an applicator device (7) during the subsequent step of applying the strip of sealing agent to the surface (2).

Abstract: A method of selectively controlling the self-sealing ability of a tire obtained by application of a sealing assembly on a drum and subsequent formation thereon of a precursor of a green tire inclusive of liner and carcass, followed by shaping, curing and molding. The sealing assembly includes: a self-supporting thermoplastic film of polyamide or polyester and a layer of sealing material possessing viscoelasticity and stickiness features, which is associated with and supported by the self-supporting thermoplastic film. The sealing assembly is easily puncturable by a sharp-pointed element while it maintains such a deformability and stickiness that it helps in the transfer of the sealing material during ejection of the sharp-pointed element and limits the transferred material amount to such an extent that holes bigger than a predetermined value are not sealed.

Abstract: A pneumatic tire is provided which includes an outer circumferential rubber tread and a supporting carcass. A rubber inner liner is disposed inwardly from the supporting carcass. A built-in sealant layer is situated adjacent to an innermost removable barrier layer and disposed inwardly from the rubber inner liner. The built-in sealant layer provides self-sealing properties to the pneumatic tire. The pneumatic tire, with its innermost removable barrier layer, keeps the sealant layer from sticking to a tire-building apparatus during tire assembly and, after curing of the assembled tire, is eventually removed to permit gas from the built-in sealant layer to become part of the tire's inflation air to prevent or reduce instances of inner liner blister formation.

Abstract: This invention relates to a pneumatic tire having a built-in non-black colored sealant layer and its preparation. The sealant layer is derived from a sealant precursor layer comprised of a butyl rubber, organoperoxide, particulate, synthetic amorphous silica and plant-derived organic agricultural seed flour, together with a non-black colored colorant. The butyl rubber-based sealant precursor layer is build into the tire to form a tire assembly and the butyl rubber component of the sealant precursor layer is depolymerized during a subsequent curing of the tire at an elevated temperature in a suitable mold to form the tire having the resultant built-in sealant. The particulate plant derived organic agricultural seed flour is a renewable raw material in a sense that it can be replenished in nature and therefore not as a significant depletion of non-renewable natural resource. The agricultural plant seed flour is comprised of at least a portion of a ground plant seed (e.g. whole or partial seed portion including for example its nucleus and/or shell) of an agricultural seed producing plant such as, for example, wheat, rye, rice, barley, oat, mullet, soybean and/or corn. The sealant layer may also contain one or more of a liquid polyisoprene and short organic fibers. Preferably, the amorphous silica is a precipitated silica, namely aggregates of primary silica particles.

Abstract: This invention relates to a pneumatic tire with puncture sealing property and a method for preparing such tire. Such tire is prepared by building an uncured butyl rubber-based layer, which contains a peroxide and a dispersion therein of a particulate precured rubber selected from pre resin-cured butyl rubber and/or pre sulfur-cured diene-based elastomer, into an uncured tire and between an innerliner layer and the tire carcass. Upon curing the prepared tire under conditions of elevated temperature, a major portion of the uncured butyl rubber composition is depolymerized to form a tacky material, which contains said dispersion therein of said particulate precured rubber, which has puncture sealant properties. Such layer of depolymerized butyl rubber and dispersed precured rubber particles may be collectively referred to as the sealant layer.
