Abstract: A device for inflating and sealing an inflatable object comprising an air-tight tube, at least one hermetic connector reversibly coupled to either end or both ends of said air- tight tube and a source of pressure connected to either one end, second end or said at least one hermetic connector. The airtight tube serves as both storage means and transfer means for a sealing agent. The device allows transfer of said sealant agent in a largely laminar flow, aiding solid and semi-solid materials in said sealant agent to align in the direction of said flow and pass securely throw the valve mechanism without clogging. The inflatable object may be inflated and sealed without removal of the valve mechanism of said inflatable object and may be charged with pressurized gas and sealant agent contemporaneously.

Abstract: The present invention is directed to a method of making a self-sealing pneumatic tire, the tire having a tread width and a radially innermost surface having a residue deposited thereon, comprising the steps of: activating a laser to generate laser radiation; directing a pulse of laser radiation to impinge on an area of the innermost surface, the pulse of radiation having a pulse width and a fluence sufficient to remove at least part of the residue in the area to form a cleaned area; repeating the step of directing the pulse of radiation sequentially over the innermost surface to form a sequence of cleaned areas, the sequence of cleaned areas defining a stripe, the stripe following a continuous nonlinear path extending at least one circumference about the inner surface, the stripe having a stripe width W2; applying a bead of sealant in a continuous bead path extending at least one circumference about the inner surface, the bead of sealant at least partially overlaying the stripe. The invention is further directed to as such a self-sealing pneumatic tire.

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 applying a sealant layer to an inner surface of a tire and a resulting tire are disclosed. Prior to sealant application first and second balance light spots on first and second sides of the tire are identified. A starting location for the sealant bead adjacent the first side of the tire is determined as a function of the location of the first balance light spot. An ending location for the sealant bead adjacent the second side of the tire is determined as a function of the location of the second balance light spot. Balance of the tire is improved by the application of the sealant layer.

Abstract: This invention discloses a technique for replenishing the level of sealant in self-sealing tires at the time that a puncture in the tire is being repaired or when the tire is being recapped. This technique provides the tire with its original level of self-sealing capabilities and will enhance the possibility of the tire remaining in service until it can be conveniently repaired. This method involves (1) injecting a liquid sealant formulation into the sealant layer of a self-sealing tire through at least one puncture hole therein, and (2) sealing the hole or holes in the supporting carcass and the innerliner of the tire. The sealant utilized is typically liquid polyisobutylene having a weight average molecular weight of 25,000 to 200,000. The sealant formulation used can optionally also contain a colorant or a pigment.

Abstract: A self-sealing tire includes a tire body, a partition wall, and a sealant that is adapted to seal a puncture in the tire body. The tire body includes an outer circumferential wall that contacts the ground, a first side wall and a second side wall that extend from the outer circumferential wall. The partition wall is provided between the first side wall and the second side wall and defines a partitioned space between the outer circumferential wall, the first side wall, the second side wall and the partition wall. The sealant is filled in the partitioned space. The partition wall includes a partition membrane, and dividing projections that are protruded from the partition membrane. Air is exhausted from the partitioned space and the sealant is filled into the partitioned space.

Abstract: In a sealant-incorporated tire including a loop-shaped sealant chamber filled with a sealant 5 and defined between a tire body 1 and an inner liner 8 by superposing and adhering the inner liner 8 onto an inner surface of the tire body 1, a sealant charging bore 8a is formed in the inner liner 8, and the sealant 7 is charged into the sealant chamber 6 through the sealant charging bore 8a. Then, air present in the sealant chamber 6 is discharged by evacuation and thereafter, a crude rubber sheet74 is adhered in a state in which the periphery of the sealant charging bore 8a has been clamped, thereby closing the sealant charging bore 8a. Thus, it is possible to charge the sealant 7 in a short time, and also to prevent heat generated during vulcanization and formation of the tire from being applied to the sealant 7, thereby preventing the deterioration of the sealant 5.

Abstract translation: 在包含密封胶5的环状密封剂室中，通过将内衬8重叠并粘接在轮胎本体1的内表面上，将轮胎主体1​​和内衬8之间形成密封剂5， 填充孔8a形成在内衬8中，并且密封剂7通过密封剂填充孔8a被填充到密封剂室6中。 然后，通过抽真空排出存在于密封剂室6中的空气，然后在密封剂填充孔8a的周边已经被夹紧的状态下粘附粗橡胶片74，从而关闭密封剂填充孔8a。 因此，可以在短时间内对密封剂7进行充电，并且还可以防止在硫化和形成轮胎期间产生的热量施加到密封剂7上，从而防止密封剂5的劣化。
