Abstract: The invention relates to a device (1) for transporting compressed air and/or sealant into a pneumatic vehicle tire, comprising at least one gas connection (3) for connecting to at least one compressed-air source (24), at least one sealant connection (2) for connecting to at least one sealant container (6), at least two channels, wherein a first channel is a sealant transport channel (4) for transporting a sealant dispersion from the sealant connection into a pneumatic vehicle tire and a second channel is a compressed-air transport channel (5) for transporting compressed air to the sealant connection or to the sealant transport channel, wherein the sealant dispersion comprises sealant particles and compressed air as dispersion matrix, characterized in that the device has a movable switchover element (7), wherein the movable switchover element can be moved in the direction of the sealant connection by means of a compressed-air flow coming from the gas connection and has a severing portion (8) for severing a sea

Abstract: Particular embodiments of the invention include methods and apparatus for deforming a tire sidewall. Such methods include the step of providing a tire having at least one sidewall connected to a corresponding bead. A further step includes constraining at least one of the sidewall and bead from moving laterally toward the other. Yet another step of such methods includes engaging the sidewall with an inclined member. Another step of such methods includes moving at lest one of the sidewall and bead in a lateral direction away from the other until the sidewall is laterally deformed into a laterally deformed configuration.

Abstract: Provide a sealing device with which simple and reliable operation can be performed. When stored, a liquid agent container, in which a sealing agent is contained, is temporarily held above a injection unit. When the liquid agent container is forcibly pressed downward in use, the upper end of a pressing jig penetrates through an aluminum seal into the container, and the sealing agent flows out to a compressor unit is activated and compressed air is supplied into the liquid agent container to place the pressurized sealing agent into a pneumatic tire through a joint hose.
