Abstract: A method for applying a tire material such as carcass ply to a building drum in a tire building process wherein the cut leading end of the ply is caused to pressure-adhere onto the building drum by a leading-end applying and pressure-adhering roller. The building drum is caused to rotate at an angle less than one rotation, and thereafter the ply is cut by the cutter mechanism, and the building drum is further rotated to join the cut trailing end of the ply with the cut leading end, while the roller is pressure-adhering the cut trailing end of the ply against the building drum.

Abstract: A vehicle wheel that includes a valve which has a check device, with the wheel being intended for use with a pneumatic tire that even when operating as a tire which is flat or has otherwise lost pressure permits great distances to be covered at a reduced speed. To prevent misuse of the tire, in other words reinflation of a tire subsequent to flat-tire operation and before the tire has been checked for leaks, the valve is provided with a mechanism that prevents such misuse. This mechanism is pneumatically disposed in series with the check device and is installed in an open position and in such a way that it changes over into a closed position upon commencement of a flat-tire operation, with a special tool and/or special replacement parts being required in order to reestablish the open position of the mechanism.
