A method for manufacturing a tire () equipped with a communication module () consists in successively, and in the order required by the architecture of said tire, laying rubber products, notably profiled elements () and reinforcing elements on a given support in order to yield a green tire (), then in vulcanizing the green tire to yield a tire (), wherein, prior to laying one of the rubber profiled elements () on the green tire, a slot () is created starting from a surface of the rubber profiled element () and the communication module () is introduced into the slot ().

The machine includes an extrusion head having flow ducts, the inlet orifices of which are connected to the outlets of at least two extruders for supplying extruded strips made of elastomeric compounds. The outlet orifices lead into a die which is adjacent to a roller and is designed to cooperate with the latter to shape the profiled element strip. The roller has a central axis surrounded by an external surface intended to receive the profiled element strip and a means for driving the roller in rotation about its central axis. The flow ducts are mutually parallel and are perpendicular to the circumferential direction of the roller, and the profiled element strip is joined to the receiving surface of the roller along an equivalent length of at least 700 mm.

A radially expandable building drum, in which is intended for manufacturing an adapter for mounting a tire on a wheel rim, includes a central shaft, a first set of segments, and a second set of segments. All of the segments are arranged circumferentially around the shaft to form a generally cylindrically shaped external face of the drum. The segments of the first set and the segments of the second set face one another axially. The drum is structured to allow a different radial expansion of the segments of the first set in relation to the segments of the second set, between two working positions.

A crown reinforcement of a tyre includes at least one crown triangulation belt having a given width value (R). The belt essentially includes elementary widths each having a given width value (B). Each of the elementary widths has a flattened cross section and forms an angle (&#x3b1;) with a circumferential direction of the tyre, the angle (&#x3b1;) being between 10&#xb0; and 80&#xb0;. Adjacent elementary widths, which are positioned directly next to each other, are separated by a groove of a given width value (j) and are connected to each other by one or more weak bridges.

Tyre and method of manufacturing a tyre triangulation belt

A tire comprising a crown reinforcing belt formed of a plurality of reinforcing plies () superposed on one another, each reinforcing ply comprising mutually parallel threads coated in a weakly electrically conducting rubber compound and making a given angle with the said circumferential direction, characterized in that one strand of electrically conducting thread () passes right through the belt at a given point, and in that a first free end () of the said strand runs along the radially external face of the said belt and that the second free end of the said strand () runs along the radially internal face of the said reinforcing belt.

A process for manufacturing a continuous strip of self-sealing product having very low hardness, being very elastic and highly tacky, the strip being intended for feeding a converting machine, during which a thermoplastic protective film is deposited on the surface of the strip. The process includes a step during which a strip of self-sealing product P is extruded to a first cross section (S) at the outlet of the extrusion die (). The strip is surrounded over its entire perimeter using a thermoplastic film () by welding the film to itself, after having deposited the film () around the strip. The strip is calendered in order to bring it down to a second cross section (S), smaller in area than the first cross section.

Device for embedding a thread in a rubber profiled element comprising: a continuous thread feeder arranged on a structure, a moving support able to run along the structure between a raised and a lowered position. A hollow needle, comprising a canal in which the thread runs is fixed by one of its ends to the base of the moving support in the duct, and a tip at its other end capable of penetrating the rubber profiled element, a cutter arranged on the structure, comprising a rotary blade able to cut off the thread at a given distance from the tip of the needle upon each cycle of reciprocating movement of the needle. The cutter comprises a paddle arranged behind the cutting wire of the blade and intended to fold the tail around the tip of the needle just after the thread has been cut by the blade.

A device is provided for depositing a treatment substance on the surface of a moving thread. The device comprises a tank configured to contain a liquid solution of the substance that is used to deposit the substance on the surface of the thread. The device also includes at least one nozzle having a nozzle inlet configured to receive said solution. The at least one nozzle is directed to spray the received solution towards the thread with a spray velocity in a form of jets, and the jets converge on the thread to adjust a thickness of the solution remaining on the thread by removing excess liquid entrained by the thread. The device further includes a pump that is coupled to the nozzle inlet and a treatment apparatus. The pump is configured to regulate the spray velocity according to a run speed of the thread.

High-speed wire coating device and method

A device for adjusting the delivery rate of a linear element. The device forms a delivery path for the linear element between an inlet to the device at a delivery rate that is substantially constant and an outlet from the device at a delivery rate that is variable and substantially periodic and varies the length of the path of the linear element in application of a predetermined periodic relationship. The device includes a plurality of pulleys movable in rectilinear translation periodically in sinusoidal manner.
