摘要： A torpedo for an extruder comprises: longitudinal member (9) which is provided at the periphery thereof with a plurality of thread portions (12) which protrude outwards and which are spaced apart in the circumferential direction; a plurality of sluice blades (19) which are mounted so as to be movable on the longitudinal member and which are partially engaged in apertures (18) of the longitudinal member, the longitudinal member (9) and the sluice blades (19) being provided with complementary radial guiding surfaces (13, 14, 18) which are in contact with each other; and adjustment means (28) for radially displacing the sluice blades relative to the longitudinal member. The sluice blades extend through the spaces between the thread portions, respectively. The thread portions (12) and the sluice blades (19) are provided with complementary radial guiding surfaces (13, 14, 18).

摘要： The manipulator device includes a pedestal and a carrying mechanism which carries a platform and which forms an articulated triangle comprising: a first arm borne by a first carriage with a first pivot link whose axis forms a first vertex of the triangle, a second arm borne by a second carriage with a second pivot link whose axis forms a second vertex of the triangle, a seat situated at the intersection of the first arm and of the second arm, which forms a third pivot link whose axis is parallel to the first pivot axis and the second pivot axis and forms a third vertex of the triangle. A module is provided for servocontrolling the translational movements of the first carriage and the second carriage with respect to the pedestal. A yaw orientation interface comprises a fourth pivot link, by which the platform is articulated on the seat, both relative to the first arm and relative to the second arm, about a fourth pivot axis which is coaxial to the third pivot axis.

摘要： The method for the coextrusion of a complex profiled element made up of the assembly of profiled elements formed from distinct rubber compounds. A coextrusion machine comprises upstream and downstream extruders which deliver into an extrusion cavity. A first profiled element, formed of the first rubber compound, is created. The first profiled element comprises at least a first profiled-element portion which is intended to form a longitudinal insert, a base of which is in continuity of material with the first profiled element. A complex profiled element formed of the first and second rubber compounds is created. The insert is circulated between walls of a channel extend in a longitudinal direction between the upstream profiling blade and the downstream profiling blade and together form a concave surface open towards the inside of the extrusion cavity in such a way that the bringing-together of the lateral walls of the insert with the second compound takes place only in the downstream gap.
