A method for manufacturing a tire () comprises a step of positioning a reinforcing ply () in a rubber material having grooves () such that the reinforcing ply () extends through the grooves (), and of crosslinking the tire () based on uncured rubber material while hot moulding the latter, with the reinforcing ply () being pushed against the bottom of the grooves ().

Method for manufacturing a tire with reinforced tread blocks

A method for manufacturing a tread () based on uncured rubber material comprises the steps of forming a green form () of tread based on uncured rubber material having at least one tread pattern () block (), each tread pattern () block () having a central portion () and at least one lateral portion () extending along the central portion (), of mounting at least one reinforcing ply () on at least a part of the central portion (), and of covering the central part () with the aid of the lateral portion () in order that the tread pattern () block () envelops the reinforcing ply ().

Method for manufacturing a tire with obliquely reinforced tread blocks

The present invention relates to a process for electroplating an adhesive composition onto at least one conductive element, in which the conductive element is placed in contact with the adhesive composition comprising: a phosphate salt and a resin based on: a compound A1, compound A1 being chosen from a compound A11 comprising at least two functions, one of these functions being a hydroxymethyl function and the other being an aldehyde function or a hydroxymethyl function, or a compound A12 comprising at least one aldehyde function, or a mixture of a compound A11 and of a compound A12; and a phenol A21. A potential difference is applied between the conductive element and the adhesive composition to coat the conductive element with an adhesive layer.

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.

A torpedo for an extruder comprises: longitudinal member () which is provided at the periphery thereof with a plurality of thread portions () which protrude outwards and which are spaced apart in the circumferential direction; a plurality of sluice blades () which are mounted so as to be movable on the longitudinal member and which are partially engaged in apertures () of the longitudinal member, the longitudinal member () and the sluice blades () being provided with complementary radial guiding surfaces () which are in contact with each other; and adjustment means () 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 () and the sluice blades () are provided with complementary radial guiding surfaces ().

ABSTRACT This weaving machine () includes a structure () able to support a plurality of warp threads () extending in a first direction, a heddles mechanism () capable of selectively moving at least some of the plurality of warp threads () to form first and second sheets () of warp threads, and at least one weft-thread feed spool (). The weaving machine () also includes at least one support shuttle () for the feed spool and an actuating device () able to control a movement of the shuttle () between the first and second sheets () of warp threads in at least one second direction transverse to the first direction, in both senses relative to the second direction, to continuously lay the weft thread () coming from the feed spool () between the sheets () and in the second direction.

A head (), for the co-extrusion of a complex rubber profiled element, includes a lower wall () of cylindrical profile, a first extrusion unit (B) having a first extrusion duct () divided into various sub-ducts (----), a first profiling blade () defining a first shaping profile (P) that is discontinuous, a second extrusion unit (B) including a second extrusion duct () divided into various sub-ducts (----), a second profiling blade () including at least one tooth (---) situated in the continuation of a divider (---), and this second profiling blade (P) incorporating at least one third extrusion duct, each outlet of a third extrusion duct closely adjoining a tooth (---) of the second profiling blade (), and a third profiling blade () defining a final shaping profile (P).

Head for the co-extrusion of a complex rubber profiled element intended for the manufacture of a tire

A head is provided for the co-extrusion of a complex rubber profiled element for the manufacture of a tire. The head makes it possible to co-extrude a sublayer and a tread with inserts. To this end, the head includes, from upstream to downstream: a) a first extrusion duct divided into various sub-ducts, b) a discontinuous first profiling blade, c) a second extrusion duct divided into various sub-ducts, d) a discontinuous second profiling blade incorporating at least one third extrusion duct in the continuation of a divider, and e) a first profiling blade having a projecting tooth in front of and next to each outlet of a third duct in the transverse direction.
