Rigid core in two parts, for manufacturing tires

The core consists of a number of adjoining circumferential sections with their transverse faces in contact with one another, and with the transverse faces of at least one section converging radially outwards. Each of the sections is fitted to a coupling member for joining all the sections to a rim,...

Beschreibung
Zusammenfassung:The core consists of a number of adjoining circumferential sections with their transverse faces in contact with one another, and with the transverse faces of at least one section converging radially outwards. Each of the sections is fitted to a coupling member for joining all the sections to a rim, with the main part of each section made from a different material to the coupling member. The core consists of a number of adjoining circumferential sections with their transverse faces (10d1, 10i1) in contact with one another, and with the transverse faces of at least one section converging radially outwards. Each of the sections is fitted to a coupling member (12) for joining all the sections to a rim (14), with the main part (13) of each section made from a different material to the coupling member, especially from a molded material that is a good conductor of heat and containing at least one electrical resistance. The materials are designed so that there is no play between the main sections when the core is at moldings temperature, while clearances appear at lower temperatures.
