Abstract: A method for determining the operating parameters of a device for manufacturing a reinforcement from a thread (1) laid directly in its final position by projecting lengths of thread (10) onto a receiving surface (S).

Abstract: Device for manufacturing a reinforcement from a thread laid directly in its final position by spraying lengths of the thread onto a receiving surface. The thread lengths are delivered from a conduit to a guide as the conduit rotates about an axis. The guide includes deflectors forming therebetween a slot having a thread inlet orifice and a thread spray (discharge) orifice spaced apart along the guide's height. The separation between the deflectors narrows toward the spray orifice, wherein the deflectors form therebetween an angle in the range of 3° and 7° when measured at any point along the height of the slot.

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 device for laying reinforcement cords (41) of a tire. The device is formed of a first frame (1) comprising a motor-driven shaft (10) with an axis XX?, the motor-driven shaft (10) supporting a reference form on which the blank (4) of the tire rests. The first frame (1) itself is mounted rotatably about an axis ZZ? on a second frame (2) in such a manner that the axis ZZ? has a point of intersection with the axis of rotation XX? and belongs to the equatorial plane (E) of the blank (4) or of the reference form on which the blank rests. A third frame (3) is rigidly connected to the second frame (2), the third frame (3) supporting an apparatus (13) for laying the lengths of cords (41) by projection of the lengths of cords directly into their final position on the receiving surface formed by the tire blank (4).

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.
