Abstract
In manufacture of an automobile tire, a method and a device for making a bead apex/bead ring assembly. More particularly, a method and a device for automatically applying an extruded belt-like rubber material generally referred to as "bead apex" or "bead filler" onto a core material referred to as "bead ring" which is previously mounted on a circular holding device referred to as "former" to make a bead ring/bead apex assembly. In the proposed method and device, the "apex" is drawn out from an extruder or a roll and fed to the "bead ring" and, then it is wound around and bonded to the outer periphery of the "bead ring" with rotation of the "former", and at least the leading end of the apex is caught and restrained by a holding device during at least a period from the start to the end of the apex applying process.
