The invention is directed to a posing assembly () that effects transfer and posing of a semifinished product () that is destined for inclusion in a tire. The invention is also directed to a tire production system () for transferring and posing a semi-finished product () that is destined for inclusion in a tire, which system includes the disclosed posing assembly. A method is provided for transferring and posing a semi-finished product () upon a rotating forming drum () having a circumferential forming surface () during a product posing cycle, which method includes a step of providing a tire production system as disclosed.

A method of manufacturing a strip of rubber having discontinuous reinforcer segments includes a conveying step in which a rubber strip is conveyed in a direction DC, and a cutting step in which reinforcers of the strip are cut. The cutting step includes localized heating of each reinforcer using a laser beam from a remote source. A cutting device useable to perform the cutting step includes a conveying device and a cutting head. The conveying device moves the strip in the conveying direction DC past the cutting head. The cutting head includes an emitter from which at least one laser beam is produced to cause localized heating of at least one reinforcer of the strip, in order to cut the at least one reinforcer into discontinuous reinforcer segments. The strip may be conveyed continuously or discontinuously, such that the strip may be moving or immobilized during the cutting step.

A self-contained device intended to be carried by a wheel-tire assembly in order to locate whether the assembly is positioned on the right side or on the left side of a vehicle is described. The device includes two magnetic sensors with axes of maximum sensitivity, the sensors providing two periodic signals that are phase shifted relative to one another. Each signal is representative of variations in the magnitude of the magnetic field detected by the sensor during a revolution of the wheel-tire assembly. The device also includes a processing unit programmed to determine, from the phase shift between the two periodic signals, a direction in which the wheel-tire assembly is rotating and to deduce, from this direction of rotation and from a direction of travel of the vehicle, whether the wheel-tire assembly is located on the right side or on the left side. The two magnetic sensors are intended to be positioned on the wheel-tire assembly at distinct azimuthal locations. A filtering element of the device is designed to eliminate components of the two periodic signals having frequencies that are below or equal to a given frequency.

In an electronic device for counting the number of rotations for a tire and wheel assembly, a storage means holds counting information (NbRot) intended to represent the number of rotations counted at each moment. The counting information (NbRot) represents the number of rotations counted from a predetermined time.
