A method for making a carcass for a pneumatic vehicle tire includes building up a carcass free from sidewalls with an inner liner, a single-ply or multi-ply carcass inlay and bead cores, at a carcass station on a carcass building drum, while creating ply turnups. The carcass produced without sidewalls is transferred to a transfer device. The carcass is kept on the transfer device while applying sidewalls to the carcass. The carcass is retained on the transfer device while transferring the carcass provided with the sidewalls to a shaping machine where the carcass is shaped into a toroidal shape.

System and method for making a carcass for a pneumatic vehicle tire

The invention is directed to a method for making a vehicle tire having a tire carcass defining an axial center, a first and a second tire bead, a tire belt and a tread. The carcass is completed on a carcass drum wherein the carcass drum is free of sidewalls. The tire carcass is removed from the carcass drum and moved to a transfer position for arranging sidewalls. The sidewalls are arranged on sidewall drums on sides of the carcass. The sidewall drums are moved in axial direction toward the axial center of the tire carcass. The sidewall drums with the sidewalls are expanded and connected to the tire carcass. Thereafter, the sidewall drums are collapsed and moved outward and the tire carcass is released for further transport. The carcass and the attached sidewalls are transferred to a shaping drum where the tire carcass with the sidewalls is shaped.

Method for making a vehicle tire

A method for making a vehicle tire in which a tire carcass is expanded radially on a shaping drum, wherein the sidewalls arranged on the tire carcass are turned up by inflatable shaping bladders. This involves moving two pusher bells, which are arranged to the sides of the tire carcass, in the direction of the center of the blank, wherein the pusher bells are respectively mounted on a movable first and second carriage and are respectively moved in the axial direction by a first and second drive by way of a coupling, wherein the pusher bells are pressed laterally against the shaping bladders. When disequilibrium of forces on the two sides of the shaping bladders is set, the pressing positions of the two pusher bells are balanced, the two drives being arranged on a freely mounted third carriage.
