Device, an installation, and a method for applying a rubber strip against a tire blank

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.
