The invention presents a device and a method for placing and attaching a strip inside a tire. Specifically, the tire is positioned on a mounting in relation to a centering means, and an adhesive device is placed inside the tire. While the tire is rotated, the strip is moved inside the tire, wherein a pressure force is applied to said strip. The strip is driven at a linear speed greater than the rotation speed of the tire, thus producing an effect of compressing said strip, the length of which becomes less than the nominal length thereof, thus creating a space between both ends of the strip such that, after release, the strip scrapes the adhesive device, which is repositioned on said ends, thus simultaneously causing said ends to be attached end to end.

An embodiment of the present invention provides an air injection valve-integrated spray for spraying and applying polyurethane foam to a desired portion of a tire. The spray includes a polyurethane foam chamber disposed at an end of a coupling portion and keeping polyurethane foam under pressure and an air delivery chamber delivering air injected from an air injection valve to a breaking portion of the polyurethane foam chamber, in which the breaking portion of the polyurethane foam chamber is broken by air coming out of the air delivery chamber, so the polyurethane foam is sprayed.

A method and a system (1) for applying a layer (2) of sound-absorbing material to the inner surface (3) of a cavity (4) of a pneumatic tyre (5) comprising an applicator device (9) having an applicator roller (10) for implementing the 5 application of the layer (2) of sound-absorbing material to the inner surface (3) after the removal of a lining (8) and arranged, in use, at a position directly facing and in proximity to said inner surface (3) and at a distance from the inner surface (3) that substantially approximates the thickness of the layer (2) of sound-absorbing material; a roller (11) for winding the lining (8) after the 10 separation from the layer (2) of sound-absorbing material; and synchronization means (13) implemented by means of a transmission member (14) in order to make it possible to maintain substantially uniform the speed of the applicator roller (10) and the winding roller (11).

A pneumatic tire includes an inner liner including a vulcanized rubber composition such that a number of voids each having a volume of 4.19 μm.sup.3 or more per 8,000,000 μm.sup.3 in the vulcanized rubber composition is 2 or less in an environment of 60° C. under an atmospheric pressure, and that the vulcanized rubber composition has an air permeation coefficient of 0.95×10.sup.−10 cm.sup.3.Math.cm/(cm.sup.2.Math.s.Math.cmHg) or less when measured using a differential pressure method in the environment of 60° C.

A method of preparing a tire with self-sealing properties, the method including the steps of providing a cured tire, the tire including a first bead, a second bead, a carcass layer extending from the first bead to the second bead, and an optional innerliner layer disposed interior to the carcass layer; directly or indirectly applying a sealant composition to at least a portion of the carcass layer or to at least a portion of the optional innerliner; and directly applying an air barrier composition to at least a portion of the carcass layer or to at least a portion of the optional innerliner.

Techniques for managing real-time business event analysis and monitoring are provided. In some examples, a logical request may be received at a business intelligence server configured with a continuous query service. Additionally, the continuous query service may be configured to translate the logical request into a physical request. Further, business intelligence information may be provided based at least in part on querying against an event data stream with a continuous query configured based at least in part on the physical request translated by the continuous query service.

A portable compressor for a tire repair kit comprises an adaptor mobile or removable from a force transmitting use position, the adaptor having an upper edge projecting with respect to an outer side wall of the compressor and defining a seat for a container of sealing fluid, the upper edge being spaced in use from a surface on which the compressor rests; and being configured to define a side support by means of a force transmission to the compressor to oppose an excessive inclination of the container of sealing fluid during the injection of sealing fluid by means of pressurized air.

Provided is a pneumatic tire having sufficient sealing performance. The present invention relates to a pneumatic tire including a sealant layer located radially inside an innerliner, the sealant layer being formed by applying a sealant to the inner periphery of a tire from which mold release agents have been removed.

A method for manufacturing a raw blank of a tyre includes using a calender to produce a ply. The calender includes two rollers with a gap situated therebetween. A ply that includes a first rubber material is formed in the gap of the calender, with a bead of the first rubber material being formed upstream of the gap. The bead and the gap of the calender are fed with a second rubber material, different from the first rubber material, to form at least one insert in the ply.

A method of manufacturing a tread for agricultural tires, the method comprising providing an agricultural tire casing, providing a cured rubber component having first and second planar surfaces, providing a plurality of cushion gums, wherein the plurality of cushion gums contains a cure system comprising a stable dinitrile oxide compound, providing a plurality of lugs, and forming an agricultural tread composite by mating the lugs to a planar surface of the cured rubber component using the cushion gum.
