Abstract: 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? is oriented horizontally, and a second line of stations (200, 300, 300?), oriented in a horizontal direction YY?, perpendicular to the direction XX?, in which the stations are capable of receiving a core (N) whose axis rr? is oriented vertically. The first line of stations comprises a first (120) and a second (130) station for assembling the tire including member (121, 131) for grasping and driving the core (N) in rotation about a horizontal axis rr?, merged with the axis XX?, such members being placed opposite one another.

Abstract: A cooling device (230) for a core (N) composed of plural elements which may be dismantled and forming in the configuration used for the assembly a stable surface of revolution having a continuous form, close to the final form of manufacture of a tire, the core being used as a reference surface for the manufacture of the tires from the start of assembly through to vulcanization. The cooling device includes members for grasping and holding the core and members for setting the core in rotation about its axis rr? placed in a horizontal position. A tub (233) is provided which contains refrigerated water, in which part of the surface of the core can be immersed.

Abstract: A vehicle unloader particularly adapted for unloading trucks and trailers used to transport sugar cane, which comprises a sloping jib, a lifting mechanism consisting of a motor, a pulley mounted at one end of the jib, a first cable passing over the pulley and attached to a hook, and a hook positioning system consisting of a second cable attached to the hook and the jib, a cylinder for varying the tension of the second cable, a three-position selector having a first position causing the cylinder to move so that the hook is brought towards the jib, a second position causing the cylinder to move so that the hook is allowed to move in the opposite direction away from the jib and a third position causing the cylinder to be isolated; a power source; and a control unit the operation of which is dependent on the amount of power absorbed by the motor of the lifting mechanism and which connects the cylinder to the power source and ensures that it is supplied with reduced power from the source when the hook is loaded an
