TAMBOUR DE CONFECTION D'UNE BANDE DE ROULEMENT MUNI DE SECTEURS RETRACTABLES |
摘要 |
A drum for building a green tire casing having: sectors that form a circumferential face of the drum, and at least one cam for controlling a radial movement of the sectors with respect to a rotation axis of the drum. The cam has two main faces and is designed such that a monotonous movement of the cam first of all causes the radial movement of some of the sectors by virtue of ramps situated on its first face without modifying a radial position of the other sectors, and then causes the radial movement of the other sectors by virtue of ramps situated on its second face, the movement of all of the sectors then being simultaneous. |
