摘要： Method of manufacturing a tire (1) by winding contiguous strips onto a rotary form at a pitch and in a number of turns that is suited to the desired profile. The method comprises steps that include laying a strip to form the sublayer (13) onto the plies (15) that form the crown reinforcement belt, the strip being made of a rubbery material that is a poor conductor of electricity, laying one or more strips to form the first part of the tread (11A), these being positioned axially on one side of the tire, the strip or strips being made of rubbery materials that are poor conductors of electricity, and laying a strip to form the insert (10) and that is laid in such a way that at least one radially interior turn (100) is in contact with the sublayer (10), the strip being made of a rubbery material that is a conductor of electricity. A localized pitch offset (130) is created when winding the strip that forms the sublayer (13), the pitch offset being positioned axially in line with the radially interior part of the insert (10), so as to make the turns non-contiguous.

摘要： A device that enables a rubber strip to be applied to a tire blank. The device comprises a rubber extruder provided with an extrusion orifice for shaping the rubber strip and delivering said strip from the extruder. The orifice is defined by a roller mounted to rotate on the extruder. The device further comprises thrust means for thrusting the roller against the blank so that the roller constitutes an applicator for applying the rubber strip against the blank. The extruder is mounted to pivot about an axis so as to form a lever on which the thrust means act to thrust the roller against the strip.
