摘要： Method for regulating an extrusion device for the manufacture of a continuous strip of profiled product (P) made of an elastomeric compound, comprising a screw rotationally driven in a fixed barrel the outlet of which comprises an extrusion die and at least one rotationally driven cylindrical roller, the rotational speed of the screw (Ωscrew) being directly connected to the rotational speed of the roller (Ωroller) by a proportionality coefficient, including: for a given elastomeric compound and a given profiled product (P), determining a setpoint value Ks of the proportionality coefficient, measuring the thickness (e) of the profiled product (P) leaving the extrusion die at each instant and correcting the value of the proportionality coefficient to Ks′, correcting the rotational speed of the screw taking account of the corrected value Ks′ of the proportionality coefficient, such that Ω′screw=Ks′*Ωroller The roller speed is adjusted as a function of the corrected value Ks′ of the proportionality coefficient.

摘要： The invention relates to improving the endurance of a bead of a radial tire for a heavy vehicle of construction plant type by reducing the compression to which the turn-up is subjected when the tire is driven on. According to the invention, for a tire for a heavy vehicle of construction plant type comprising two beads intended to come into contact with a rim having two rim flanges, a carcass reinforcement comprising at least one carcass reinforcement layer having a main part wrapped, within each bead, from the inside towards the outside of the tire, around a bead wire of substantially circular meridian section, to form a turn-up, a filling element extending the bead wire radially towards the outside and axially separating the main part and the turn-up, the distance (d) between a first segment of turn-up and the main part decreasing continuously, radially towards the outside, from the bead wire as far as a minimum distance (d1), the distance (d2) between a second segment of turn-up, extending the first segment of turn-up radially towards the outside, and the main part is substantially constant and equal to the minimum distance (d1) between the first segment of turn-up and the main part.

摘要： A tread and tire for a multipurpose agricultural machine, that improves field traction while ensuring a satisfactory compromise with wear under engine torque and vibratory comfort on the road having a tread having a plurality of lugs distributed in a first row extending axially from a first axial end of the tread and in a second row extending axially from a second axial end of the tread, the second row differing from the first row by a symmetry relative to the equatorial plane of the tire followed by a rotation about the rotation axis of the tire, each row having an alternation of long lugs and of short lugs. The axially inner end face of a first long lug of a row of lugs is separated from the trailing lateral face of the second long lug of the symmetrical row of lugs, closest to the axially inner end face of the first long lug, by an end groove with a width at least equal to 10% and at most equal to 100% of the lug height.

摘要： A snow tire tread having a plurality of blocks separated by grooves and provided with sipe incisions dividing into several parts from a certain depth onwards, (complex sipes each having, when viewed in cross section, a rectilinear first part extending radially from the tread surface of the tread, and a second part extending the first part and comprising at least two branches each having an end. The tread has cavities each extending between the branches of a complex sipe and having a bottom situated at the same level as the ends of the branches. The cavities and the grooves of the tread are configured so that this tread has a voids surface ratio at the end of wear greater than or equal to 35%.
