A device for changing the rotational angle position of a pneumatic tire relative to a rim, on which the pneumatic tire is fitted to the rim, includes a manipulating device with a gripper adapted to be rotated by a positionable rotary drive mechanism and having radially adjustable gripper fingers with oppositely facing lift-off devices. Via the gripper it is possible to load a wheel into a clamping fixture, and following unseating of the tire beads from the clamped rim the pneumatic tire can be rotated relative to the rim through a computed angular difference.

Device and method for changing the rotational angle position of a pneumatic tire on a wheel rim

Method for mounting a pneumatic tire on a well base rim of a motor vehicle wheel, in which the pneumatic tire is grasped by means of a manipulator, brought up to a rim held in a clamping device and slipped with at least the one tire bead facing the rim over a rim flange by controlled movement of the manipulator.

Method for mounting a pneumatic tire

A pneumatic tire filling station includes a support and seal arrangement on which one side wall of the tire is supported and sealed, and a tire filling bell that presses and seals against the opposite side wall of the tire and then supplies pressurized air into the tire. The filling bell includes outer and inner rings that are concentrically slidable relative to each other. One of the rings is selected for the filling operation depending on the size of the tire. The support and seal arrangement includes plural plate members that are joined and sealed together to form a continuous support and seal surface, or moved laterally apart to allow a transport apparatus to carry and support the mounted tire from underneath. The tire filling station is adaptable to different models and sizes of mounted tires even in a mixed process flow, in an automated manner.

Tire filing method and apparatus adaptable to different sizes of tires

An apparatus for improving the fit of a pneumatic tire on a wheel comprises a plurality a conical pressure rollers. A first pair of pressure rollers with their larger diameter positioned downwardly are arranged diametrically opposite each other with respect to the axis of the tire. A second pair of pressure rollers with their larger diameter positioned upwardly are arranged similarly diametrically opposite the pressure rollers with their larger diameter upwardly are arranged alternately with pressure rollers with their larger diameter downwardly in the peripheral direction of the tire.
