Transfer ring, tire building assembly and method for transferring one or more tire components

A transfer ring for transferring one or more tire components, wherein the transfer ring comprises a frame that extends circumferentially about a central axis defining a central aperture for receiving a tire building drum, wherein the transfer ring comprises a plurality of holding members for holding the one or more tire components during transfer of said one or more tire components by the transfer ring, wherein said holding members are distributed circumferentially about the central axis, wherein the transfer ring further comprises a radial drive for moving the holding members with respect to the frame in a contraction direction towards the central axis and in an expansion direction away from the central axis, wherein the radial drive comprises, for at least one holding member of the plurality of holding members, a first drive member that is arranged for translational movement with respect to the frame with at least a vector component in the contraction direction and the expansion direction and a second drive member, supported by the first drive member, that is arranged for translational movement with respect to the first drive member with at least a vector component in the contraction direction and the expansion direction.
