发明名称 Method of Manufacturing a Tire Comprising an Electrically Conductive Insert by Winding of Strips
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.
