A machine for manufacturing tires (P) using at least one core (N) used as a reference surface of the manufacture of the tires (P) by moving consecutively from one manufacturing station to another from the start of assembly through to vulcanisation, comprising a first line of stations, oriented in a horizontal direction XX', capable of receiving the core whose axis of rotation rr&#x2032; is oriented horizontally, and a second line of stations (&#x2032;), oriented in a horizontal direction YY&#x2032;, perpendicular to the direction XX&#x2032;, in which the stations are capable of receiving a core (N) whose axis rr&#x2032; is oriented vertically. The first line of stations comprises a first () and a second () station for assembling the tire including member () for grasping and driving the core (N) in rotation about a horizontal axis rr&#x2032;, merged with the axis XX&#x2032;, such members being placed opposite one another. A turning device () is movable in the direction XX&#x2032; and is capable of transferring the core from one station to another within the first line of stations () by making the axis rr&#x2032; of the core effect a translation along the axis XX&#x2032; and a rotation of 180&#xb0; about a horizontal axis yy&#x2032; parallel to the direction YY&#x2032;.

Machine for assembling and vulcanising tires

A process and apparatus for laying a strip for the manufacture of a tire by extruding uncured rubber through a die to form a rubber tube on a rotary support and flattening the tubular form to form a band which is adhered to a receiving surface on the rotary support.

Manufacture of a strip by extrusion of a tube then flattening the tube

A tire vulcanization apparatus in which an encaser 3 makes it possible to introduce a tire into a mold 1 and, by means of inductors 42, transfers to the mold heat energy necessary for vulcanization and in which a chamber 5 receives several molds 1 and makes it possible to maintain each mold insulated from the environment in order to limit heat losses during the time necessary for the vulcanization.

Process and apparatus for the vulcanizing of tires

A pair of hooks for the manufacture of a tire reinforcement from a cord in which one of the hooks (32) is articulated relative to the other hook (31). It is designed in such a manner as to permit hooking of a loop of cord on both hooks, to insure grasping of one and only one strand of the loop of the cord by the second hook (32) to maintain the loop open for the insertion of a bead wire, and to optimize the position of the hooks during both the hooking and the unhooking phases.
