Abstract: Two opposed coaxial discoidal elements (35, 37) are diametrically dilatable and are able to move independently of each other axially and pass axially into the tire (P) when the tire is positioned in the mold, in such a way as to dilate each of said discoidal elements (35, 37), for engaging a corresponding annular bead (P1, P2) of the tire and positioning it exactly against the edge of the respective pan (13, 15).

Abstract: In a tire vulcanizing machine--comprising an element for moving the tire and a mold with several segments carrying mold sections that can move radially--the top section of the mold is held by said element, which can move axially and angularly to occupy one position in which it can collect the untreated tire, one position in which it places the tire into the mold and one position in which it unloads the vulcanized tire onto devices which collect and remove it; element comprises devices which engage the upper rim of said tire on the top section of the mold in the collection position; devices for centering said rim with respect to the top section of the mold are also provided.

Abstract: An apparatus for handling tires to be placed in a vulcanizing machine--particularly for retreading the tread or the whole tire--and for the removal of the tire from the machine, comprises: a housing developed along and behind the front of a set of such machines. The housing has a conveyor and slide rails. A carriage is movable on the rails so that it can reach transfer positions near each of the machines. An arm with a plurality of sections and having several degrees of freedom include a drawing device to engage the upper rim of a tire in horizontal position, to transfer it from an open mold on to the conveyor, and to transfer it from a drawing position as far as the open mold of a machine.
