Abstract
A method for manufacturing a pneumatic vehicle tire includes the step of providing a cylindrical building drum with a bar or depression having a longitudinal extension in the direction parallel to the orientation of reinforcement elements of a carcass ply to be applied to the building drum. A lining is positioned on the cylindrical building drum. At least one carcass ply, comprising reinforcement elements and having a leading end and a trailing end, is placed onto the lining such that the leading and trailing ends overlap in the overlap zone at the bar or the depression, thereby forming an overlength of the reinforcement elements in the overlap zone for preventing a constriction in the overlap zone within the vulcanized, inflated tire. In the alternative, the carcass ply is folded in the overlap zone into a least one fold to form an overlength of the reinforcement elements in the overlap zone for preventing the constriction in the overlap zone within the vulcanized, inflated tire. In this embodiment, the bar or depression at the drum is not required. Subsequently, in both methods, the green tire is completed on the building drum and the green tire is then vulcanized to produce the …
